3.3.2 Load and logic voltage
Load voltage The power electronics and thereby the motor are supplied
with DC voltage via the power supply connection.
• Use the power supply cable KPWR-MC-1-SUB-9HC-...
(max length of 10 m).
• For the load voltage supply, use a stabilised power supply
unit with high reserve capacity and external fuses.

Tab. 3/3: Connecting the power supply to the motor unit
Regulated DC motors consume many times their nominal
operating current when switched on or when producing the
startup torque. These consumers represent an overload or
short-circuit to the power supply at these times.
Power supplies with a U/I output characteristic curve still
provide the full output current (at a lower output voltage)
under heavy loads or short-circuits.
Power supplies with additional power reserves (Power Boost)
provide a constant output voltage, even under overload
conditions. Power supplies with a U/I output characteristic
curve and additional power reserves are therefore optimally
suited for universal industrial use.
