Cause : IR Volts Range- “Calculate” is the autotune default and the value that is determined by the autotune procedure for IR Drop Volts is not in the range of acceptable values.
- The value for P73 [IR Voltage Drop], which is calculated from the motor nameplate data, is not within the range of acceptable values, as determined by the Calculated Autotune procedure.
- Check the motor nameplate data against parameters P25 [Motor NP Volts] through P30 [Motor NP Power].
- Re-enter motor nameplate data.
