1.4.4 Holding brake
All motors are optionally available with a holding brake. A spring applied brake (24V DC) is integrated
into the motors. When this brake is de-energized it blocks the rotor.
WARNING
If there is a suspended load (vertical axes), the motor's holding brake is released,
and, at the same time, the servo drive does not produce any output, the load may
fall down! Risk of injury exists for the personnel operating the machine. The user
should consider required local safety standards in the case of hanging loads (vertical
axes) and the need to insure personnel safety by using additional safety measures
for hazard avoidance.
The holding brakes are designed as standstill brakes and are not suited for repeated
operational braking. In the case of frequent, operational braking, premature wear
and failure of the holding brake is to be expected.
The motor length increases when a holding brake is mounted.
The holding brake can be controlled directly by the servo amplifier (no personal safety !), the winding is
suppressed in the servo amplifier — additional circuitry is not required (see instruction manual of the
servo amplifier). If the holding brake is not controlled directly by the servo drive, additional wiring (e.g.
varistor) is required. Consult our support department.
