Motor holding brake: Installation instructions
Make sure the power supply is sufficient for the motor holding brake at the
motor. Take into account that voltage drops on the supply line. Use connection
lines with the largest possible cross section of single strands.
Use an external contact element in accordance with the required safety cate-
gory if you wish to supply motor holding brakes with higher currents than
the current load allowed at the connection point. Make sure to comply with
the required minimum current consumption of 100 mA when using an external
contact element. Otherwise the brake current monitor will signal an error.
