Motor holding brake: Notes on in‐
stallation
Make sure the power supply is sufficient for the motor holding brake at the
motor. Observe 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
category if you wish 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. Otherwise, the brake current monitor will signal an error.
