How do I startup & troubleshoot a PMAC motor on the 890?

The 890 series only supports closed loop PMAC control. Sensorless PMAC control is not supported. For sensorless PMAC control, the AC30 may be considered.

In North America, we initially recommend using products from Parkermotion.com for traditional servo motion control; including camming & positioning applications. Your local Parker ATC can provide support for these applications. 

The 890 drive with firmware v3.x however may also be paired with a permanent magnet AC motor (PMAC) for velocity or torque control. European PMAC motors (such as Parker's NX motor line no longer supported for new applications in North America) were often used with the 890. Today, large PMAC motors such as Parker’s MGV high speed motors, GVM Global Vehicle Motors, and TMW torque motors can certainly be utilized for 890 PMAC applications.

  1. Walks through the motor wizard configurator
     1. Selecting a pre-configured Parker motor, or necessary information to implement your own

• Troubleshoot the PMAC startup: How to troubleshoot the start-up of a PMAC motor 
  1. The troubleshooting uses the 6901 keypad as the small keypad does not have access to these options.
     1. With 8 yellow buttons, 1 green RUN button, and 1 red STOP button.
     2. The PROG button on the 6901 Keypad is also useful for switching back and forth between your location in the menus and running the motor in local mode
  2. Walks through tests involving:
     1. Inverting the feedback signal with one parameter
     2. Rotation direction verification
     3. Adjusting the electrical position offset
  3. IMPORTANT NOTE: The inverting of the Resolver / Encoder feedback counts outlined in an early step can affect operation throughout troubleshooting. If your motor does not run properly during one of the tests, make sure to invert parameter again before continuing with remaining tests (try the subsequent tests with, and without, inverting the counts).
