Rexroth IndraDrive C HCS03.1
Controlling the Motor Holding
DOK-INDRV*-HCS03.1****-PR02-EN-P
DANGER
For the current consumption of the motor holding brake see the project
planning documentation for the AC motors.
The motor holding brake of the AC motors has not been designed as a
service brake. After approximately 20,000 motor revolutions against the
closed brake armature disc it will be worn.
The drive controller can assume the control of the motor holding brake.
Brake
Note: If the drive controller controls the brake, external supply with
+24V is required.
Note: For operating Rexroth motors with motor brake, external
supply of 24 V +/-10 % is required (please also take the data
sheet of the motors into account).
Note: In the condition as supplied, control is not activated.
Dangerous movements! Danger to personnel
from falling or dropping axes!
⇒ The standard motor holding brake provided or an
external motor holding brake controlled directly by
the drive controller are not sufficient on their own to
guarantee the safety of personnel!
⇒ Personnel safety must be achieved using higher-
ranking, fail-safe procedures:
Dangerous areas should be blocked off with
protective fences or grids.
Additionally secure vertical axes against falling or
sinking after switching off the motor power by, for
example:
- mechanically locking the vertical axis
- providing external
mechanisms
- adequately counterbalancing the axis.
