5.4 Options

5.4.1 Mechanical Holding Brake

The optional mechanical holding brake is designed as a
single-disc brake. The emergency stop function can be
initiated at most once every 3 minutes and up to 2000
times in total, depending on the load.
The effective holding torque is:
•
Size 1: 2.5 Nm
•
Size 2: 5.3 Nm
The brake operates as a holding brake according to the
fail-safe principle closed when no current. It is powered
from the 24–48 V DC auxiliary supply. This enables low-
backlash load holding when no current is present.
Power consumption:
•
Size 1: 2.0 W
•
Size 2: 2.5 W
NOTICE
Do not misuse the holding brake as a working brake
because this causes increased wear, resulting in
premature failure.

5.4.2 Feedback
