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 out-
put, the load may fall down! Risk of injury for the personnel operating the
machine. Functional safety in case of hanging loads (vertical axes) can
be ensured only by using an additional, external, mechanical brake.
The holding brakes are designed as standstill brakes and are not suited for repeated oper-
ational 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 instruc-
tion manual of the servo amplifier). If the holding brake is not controlled directly by the servo
drive, an additional wiring (e.g. varistor) is required. Consult our support department.
Brake data are listed in chapter "Technical Data Brakes" from (➜ # 229) .
