Drive Differences Between ABB ACS-xxx-01E/03E/01 And ACS-xxx-01U/03U/U1

What are the drive differences between an ABB ACSxxx-01E/03E/01 and ACSxxx-01U/03U/U1

Answer: The ABB ACSxxx-01E/03E/01 drive’s motor information parameters default to the following MOTOR NOM FREQ to “50Hz”, MOTOR NOM POWER is in “Kw”, REF1 MAX to “50Hz”, MAXIMUM SPEED to “1500RPM” and MAXIMUM FREQ to “50Hz”. The EMC metal screw is installed activating the EMC filter. 50 Hertz default output and power ratings in Kilowatt are standard for drives and other industrial electrical equipment in Western Europe, the United Kingdom and most countries located outside the United States of America. This is because electric motors are sized in Kilowatt ratings outside the USA; and, electric motors manufactured outside the USA run at full load speed when operating at 50 hertz.

The ACSxxx-01U/03U/U1 drive’s motor information parameters default to the following MOTOR NOM FREQ to “60Hz”, MOTOR NOM POWER is in “Hp”, REF1 MAX to “60Hz”, MAXIMUM SPEED to “1800RPM” and MAXIMUM FREQ to “60Hz”. The EMC plastic screw is installed deactivating the EMC filter, but the drive ships with the metal screw to activate the EMC filter. 60 Hertz default output and power ratings in Horsepower are standard for drives and other industrial electrical equipment in the United States of America. This is because electric motors are sized in horsepower ratings in the USA; and, electric motors manufactured in the USA run at full load speed when operating at 60 hertz.

ABB Multi-Motor Setup With ABB Micro Drives

There are several ways to build an ABB multi-motor setup with ABB micro drives. Master-slave control, parallel control of motors and combinations of these two ways. The most typical ABB multi-motor setup for compact drives is the parallel control, which means that several motors are powered by one inverter (parallel connection of motor windings). The benefits of such approach are that there is only one inverter to startup, and that less time and effort is needed for the installation work. Multi-motor setup is possible only with asynchronous motors.

1.) Motors (3 × 1.5 kW) 2.) Load 3.) Rollers

Correct selection of drive is critical with this kind of ABB multi-motor setup. This is due to the fact that increased amount of common mode current will reduce the loading current capability of the drive. Factors that affect drive load ability and the amount of common mode current:

  • Total length of motor cabling
  • Total amount of parallel motors (motor size)
  • Amount of parallel motor cables
  • Motor cable type (shielded cable has higher capacitance than un-shielded)
  • Common output choke for all motors (thermal current must be 1.2 times total sum of motor currents)

The drive is selected based on the sum of the connected motor powers. See the table below to indicate the drive type depending the total motor power. Typically, also the use of external output chokes is recommended and the maximum motor cable length is more limited than with a single motor connection. When one drive controls several motors, only scalar control should be used. Motor parameters (PN, I2N) are given as the sum of the nominal values of the motors. Nominal speed is given as an average of the motor rated speeds. It is recommended to limit the maximum current according to the actual need and it should not exceed 1.1 × I2N (parameter 2003 MAX CURRENT). Only 4 kHz switching frequency is allowed to be used. When multiple motors are connected, the sum of the output cable lengths must not exceed the maximum allowed cable length (see table below). Cables should be separated as close to the drive as possible. If motor contactors are used, switching the contactors during operation is not recommended.

Only trained technicians should perform an ABB multi-motor setup. To learn more about ABB multi-motor setup, visit the ABB Website. For ABB low voltage drive quotes, contact Precision Electric.

De-Rating ABB Drives For Single Phase Input With ACS310 and ACS355 Series

De-Rating ABB Drives for single phase input is possible with the ABB ACS310 and ACS355 Series drives. The ACS3XX-01U drives ratings are supplied in standard ratings for a single-phase supply voltage ranging from 200 to 240 V. They would then be used to operate a three-phase motor. It is also possible to supply 230 V single phase power to some three phase drive ratings but this would require a de-rating of the output current when choosing a drive. Table Showing Drive Rating and Available Output Current When Single Phase Input Power Is Applied:

De-Rating ABB Drives for single phase input should only be performed by electrical technicians. If you’re de-rating ABB drives for single phase input, contact someone with experience before purchasing or installing equipment. To learn more about ABB drives, visit the ABB Website.

ABB Variable Frequency Drive Repair

ABB variable frequency drive repair should begin with checking the electric motor connections and drive terminal connections. Motor and drive connections can be missed, installed loosely or wired to the incorrect terminals, so checking all connections is recommended before pulling the drive for a repair evaluation. Heat cycles and mechanical vibration can lead to sub-standard connections. Reusing torque screws is not a good idea, and further tightening an already tight connection can ruin the connection. Bad connections eventually lead to arcing. Arcing at the drive input terminal can result in over voltage faults, clearing of input fuses, or damage to protective components. Arcing at the drive input or output terminals may result in over-current faults or damage to the power components. Loose connections can cause erratic operation. For example, a loose START/STOP signal wire can cause uncontrollable starting and stopping of the motor. A loose speed reference wire can cause the drive speed to fluctuate, resulting in scrap, machine damage, and personnel injury.

 

Diode and IGBT Testing

Prior to applying power during ABB variable frequency drive repairs, the input and output power sections are tested. If there is a short on the input side or output side of the drive, further damage can be caused to the unit if power is applied to it. For this reason, special meters should be used to properly test the input and output power sections of the drive prior to applying power to the drive unit. If a short is found, the drive can be disassembled and the cause of the short can be diagnosed and quoted for repair. If the drive repairs are too costly, drive replacement should be considered.

 

Power Up

If the input and output power sections test healthy during the ABB variable frequency drive repairs process, power can be applied to the drive to perform amp reading and output frequency testing. Slowly increasing the power voltage during this step of the drive repairs process is suggested to gather accurate meter readings and to protect the motor. The power voltage is slowly increased on the drive until the rated input voltage of the drive is reached. Depending on whether or not the drive provides a display will determine what further action will be taken. If display is unavailable, disassemble and diagnosis of the internal power supply of the control section of the drive is necessary to further evaluate cause of failure and establish cost and lead time of the drive repairs.

 

Motor Testing

If the previous three tests have passed during the ABB variable frequency drive repairs process, a basic JOG / RUN function of the drive can be performed with a simple template program. When a drive comes into our facility, repair techs will backup all existing programs stored in the drive prior to installing a test template program for testing. Backing up the drive program ensures that we have a backup copy of the program to install after the repair is complete. The best method for backing up drive programs will depend on the series and model of drive that’s being repaired. After the drive programs have been backed up, the drive is reset to factory default through the keypad and then recommissioned to a basic START / STOP function of the drive connected to its motor. Closed loop testing will be necessary when an encoder or tachometer is involved. If the motor will not run, the output voltages and motor current ratings are tested to verify that the drive is functioning properly to rotate the motor.

 

Safety Precautions

Manufacturers are encouraged to ensure that their ABB variable frequency drive repairs are being performed at the actual site of whoever is offering the service. Drive repairs should be taken with extreme caution and only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert in the field when repairing all industrial electrical equipment. Many drive controllers have an internal DC bus that retains a charge after power has been cut to the drive, and as a result, electrical current is still present after power is shut down. Technicians performing VFD repairs must always take extra precautions to ensure proper safety measures are taken, or injury or even death may occur.

 

Precision Electric receives ABB variable frequency drive repairs everyday from companies who offer drive repair services; those third party repair companies will have Precision Electric perform the repair, and then they will mark up the repair cost to their customers. Going straight to Precision Electric for drive repairs will prevent these added costs and prevent extensive lead times. For ABB variable frequency drive repairs and replacements, contact Precision Electric.

AC Tech Drive Repair

Should I Repair Or Replace My Drive?

Cost and Production Loss 

AC Tech drive repair can be quicker and less expensive than drive replacement. AC Tech drive repair is most economical for: obsolete drives, out of stock drives, and, drives above 10 horsepower. When a failed AC Tech drive is obsolete or the availability exceeds repair time, AC Tech drive repair can be a better solution than replacement.

AC Tech drives below 10 horsepower typically fail in eight years from their initial installation date. AC Tech drives below 10 horsepower are more often replaced than repaired because the cost of repair will exceed the cost of replacement. AC Tech drives above 10 horsepower have a longer life span, and, are more often repaired than replaced, because the cost of repair is less expensive than the cost of replacement. Depending on the cause of failure, an AC Tech drive repair can cost anywhere from 40%-75% less than the replacement cost.

There are special circumstances that would allow a maintenance technician to choose AC Tech drive repair instead of replacement, regardless of the drive cost. For example: If a crucial production line is down due to AC Tech drive failure, a maintenance technician would look at their options: 1.) AC Tech drive replacement or 2.) AC Tech drive repair. If the AC Tech product needed is not in stock and the lead time is several weeks, the quicker solution would be AC Tech drive repair. The cost of the repair in these situations would first depend on the cost of downtime. If the downtime in production loss exceeds the drive repair time, the maintenance tech would go with the drive repair.

PM Programs

AC Tech drive repair PM programs for larger (above 10hp) AC Tech drives, can prevent severe damage to AC Tech drives. Severely damaged drive repair can cost more than drive replacement, depending on the extent of board and component damage. Preventative maintenance consists of cleanup or replacement of circuit boards and all other electrical components – Followed by 100% component test and final test run with motor; PM programs are typically scheduled out once or twice a year – onsite, when necessary.

AC Tech Drive Repair – Where Should I Send My Drive?

AC Tech drive repair is an asset to manufacturers, but choosing the right source is crucial. If the manufacturer chooses the wrong repair vendor, the mfg. could end up 1.) paying too much, 2.) waiting too long, or, 3.) paying a repair vendor that’s outsourcing the repair to a third party, and marking up the cost. Precision Electric performs AC Tech drive repair every day for electrical ‘repair shops’ who offer repair services. Precision Electric suggests to all manufacturers: make sure your repair vendor is performing the repair and not outsourcing the repair.

All AC Tech drive repair services are performed in house at Precision Electric. Precision Electric replaces bad components and failed parts with the best available components and parts in the electrical industry. All AC Tech drive repair performed by Precision Electric includes a one year ‘in service’ warranty. The ‘in service’ warranty ensures that all repaired equipment will receive an entire year of warranty – the warranty begins the day your equipment is put into service. The in service warranty is especially attractive for spare drives.

AC Tech Drive Repair – Safety

AC Tech drive repair should be taken with extreme caution and only be performed by trained technicians. Most AC Tech drives have an internal DC bus that retains a charge after power has been cut to the drive. An untrained drive user can be injured if they’re unaware that power is still active on the drive. A technician working with variable frequency drives must follow certain steps and take extra precautions during a drive repair – This is to prevent injury or death during the repair.
