AMA: Parameter out of range

What does 55 mean?

The Automatic Motor Adaptation (AMA) cannot run because one or more parameter values related to the motor are outside of the acceptable range for the AMA algorithm. This indicates an invalid motor configuration that prevents the drive from accurately modeling the motor.

• One or more motor parameters (P1-20 to P1-25) are outside the acceptable numerical limits for the drive's AMA function.
• Inputting values that are inconsistent with each other, creating a mathematically impossible motor model.
• Drive firmware limitation or internal validation checks flagging an invalid configuration.
• Typographical error in a parameter value, pushing it beyond the permissible range.
• Attempting AMA with an unsupported motor type or configuration.

Click steps to track your progress.

1. 1

   1. Verify all motor parameters (P1-20 to P1-25) precisely match the motor nameplate data, checking for miskeyed digits.

2. 2

   2. Consult the drive's manual for specific parameter ranges for P1-20 to P1-25 and ensure values are within these limits.

3. 3

   3. Set all motor-related parameters (P1-20 to P1-25) to factory default (if applicable) and carefully re-enter them.

4. 4

   4. Ensure consistency between P1-20 (Motor Voltage), P1-22 (Motor Power), and P1-24 (Motor Current) based on expected motor efficiency.

5. 5

   5. Perform a full drive factory reset (e.g., P14-20 = 2) and reconfigure essential parameters before attempting AMA again.
