PowerFlex 750-Series AC Drives
Motor Considerations
Due to the operational characteristics of AC variable frequency drives, motors with inverter grade insulation systems
designed to meet or exceed NEMA MG1 Part 31.40.4.2 standards for resistance to spikes of 1600 volts are recommended.
Guidelines must be followed when using non-inverter grade motors to avoid premature motor failures. Refer to Wiring and
Grounding Guidelines for Pulse Width Modulated (PWM) AC Drives, publication DRIVES-IN001 for
recommendations.
Allen-Bradley Permanent Magnet Servo Motors
When using a PowerFlex 755 to control a permanent magnet motor, the motor feedback device must have a resolution such
that the number of pulses per revolution (PPR) is an exponent of 2 (for example: 512, 1024, 2048, 4096, 8192 and so on).
The following table contains a list of specifications for Allen-Bradley servo motors compatible with PowerFlex 750-Series
drives. This list primarily includes 460V rated MP-Series and 1326AB/1326AS servo motors. This information is provided
to help configure a PowerFlex 750-Series drive with the appropriate servo motor data. For information regarding
compatibility and configuration of Allen-Bradley servo motors (including Bulletin RDB or RDD-Series Direct Drive
Motors) and third party PM motors not listed here, contact Allen-Bradley Drives Technical Support.
