● A limited number of Emergency Stop operations is permissible.
Unpredictable movements of the machine or system because of inadequate braking
performance
If you use the holding brake incorrectly, e.g. as an operating brake or you ignore the
permissible operating energy of the brake, then the brake will be subject to excessive
and impermissible wear. As a consequence, there may be no braking effect at all.
Unintentional movements of the machine or system can result in death or serious injury.
• Observe the permissible operating energy and EMERGENCY STOP properties.
• Operate the motor only in conjunction with an intact brake.
• Avoid repeated brief acceleration of the motor against a holding brake that is still
closed.
● Do not exceed the maximum operating energy per emergency braking.
Premature wear of the motor holding brake when operated outside its permissible
voltage range
Operating the motor holding brake outside its permissible voltage range at the motor
connection will damage the brake.
• Ensure that the motor holding brake is only operated within its permissible voltage
range.
● The rated voltage of the holding brake is 24 V DC +/- 10%. Voltages outside this
tolerance range can cause disturbances.
Note
Subsequent conversion of motors with or without a holding brake is not possible.
