11.3.7 Holding brake option
All motors with DSL feedback option are optionally available with a holding brake. Retro-
fitting a brake is not possible. A spring applied brake (24V DC) is integrated into the
motors. When this brake is de-energized it blocks the rotor.
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 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 ope-
rational 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 drive (no functional safety !), the win-
ding is suppressed in the drive — additional circuitry is not required (see instructions
manual of the used drive). If the holding brake is not controlled directly by the drive, an
additional wiring (e.g. varistor) is required. Consult our support department.
11.3.8 Connection options
The hybrid cable combines power and feedback signals and is connected inside the
motor. The cable includes a tube for pressure compensation:
Codes K and T
Cable prepared for AKD-B/P/T/M. Feedback connector is assembled, Power
lines and shield is prepared for connecting the X9 connector of the drive (see
drive installation manual).
Codes N and M
(in process) Cable prepared for AKD-N. Hybrid connector is assembled for plug to the drive
(see drive installation manual).
Codes L and F Cable with flying leads for both power and feedback.
Depending on the application requirements you can select either standard (washdown)
cabling or hygienic (food) cabling.
Non food applications can be connected with washdown hybrid cable (K, L, N).
Food applications require a special solution with a tube covered hybrid cable (T, F, M).
Compatibility of the cable to cleaning solutions used in the application should be evalua-
ted before subjecting the cable to long-term exposure to chemicals. Long-term exposure
of the motor cable to chemicals not compatible with the motor cable could result in conta-
mination of product, motor failure, and electrocution hazard due to the exposure of high
voltage wiring inside the motor cable.
