Can Altivar Process Variable speed drives ATV600, ATV900 Measure Current in Each Motor Phase?

No. Altivar Process drives do not provide individual current measurements for each motor phase.

The only motor current value available from the drive is the LCR (Motor Current) parameter.

Altivar Process ATV630 and Altivar Process ATV930 variable speed drives are designed to operate with three-phase motors only. Under normal operating conditions, the motor current is balanced across all three phases. Therefore, the current in each motor phase is considered equal to the value reported by the LCR parameter.
