CAUTION
DANGER
Maximum allowed braking current:
• HCS02.1N-W0012…-W0070: 2.0 A eff
• HCS03.1N-W0070…-W0210: 2.0 A eff
Where braking currents are higher, the motor holding
brake must be activated by means of an external contact
element.
The contact elements used in the drive controller are
subject to wear. Guaranteed number of switching
actions at max. time constant of load < 50 ms
(LBrake/(24V/IBrake)): 250.000.
Maximum switching frequency: 0.5 Hz
Dangerous movements! Danger to personnel
from falling or slipping 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 higherranking,
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 braking/catching/clamping
mechanisms
- adequately counterbalancing the axis.
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.
