Measuring the motor voltage and the motor current by means of a drive controller

Question:

Can the motor voltage and the motor current be measured correctly by means of a drive controller?

Answer:

a) Motor voltage:
Yes, the effective value of the motor voltage can be measured by means of a drive controller (code C0052).

As an external instrument for measuring the motor voltage at the inverter's output we recommend a moving iron instrument.

b) Motor current:
Yes, the effective value of the motor current can be measured by means of a drive controller (code C0054).

As an external instrument for measuring the motor current we recommend a moving iron instrument or a digital multimeter (True-RMS).
