The
DC input current
of the inverter is basically determined by the
used motor. The data can be taken from the motor name plate.
The
DC input peak current
is determined by the operating range:
• if you accelerate on the hardware current limit, the short-time limit
current of the inverter must be used in the formula above (instead of
the rated motor current).
• if the motor in normal operation is never stressed with rated torque, it
can be calculated with the real motor current.
• a good practice value corresponds approx. to 1,5-times of the rated
motor current (from 90kW 1,25-times)
