DC supply

The DC input current of the inverter is basically determined by the used motor. The data can be taken from the
motor name plate.

DC
The DC input peak current is determined by the operating range.
• if you accelerate on the hardware current limit, the short-time current limit of the inverter must be used in the
formula above (instead of the motor rated current)
• if the motor in normal operation is never stressed with rated torque, it can be calculated with the real motor
current.
