Motor holding brake: Notes on in‐
stallation
Make sure there is enough power supply to the motor for the motor holding
brake. Note 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 want to supply motor holding brakes with higher currents than the
current load allowed at XG3. Make sure to comply with the required minimum
current consumption of 100 mA when using an external contact element. Oth‐
erwise the brake current monitor will signal an error.
