Technical description
6.3.8 Connection technology
The motors are fitted with rotatable, angular connectors for the power supply and the feedback signals (only
resolver).
The mating connectors are not included in the scope of supply. We can supply preassembled feedback (only
resolver) and power cables.
6.3.9 Feedback­System
Feedback­System Impulse per rotation System accuracy Comment
Resolver 16384 ± 600 Angle sec. approx.0.17° Standard
OCT 128 SinCos
(Multiturn) 33554432 ± 120 Angle sec. approx. 0.03° Option
Notice
Feedback exchange
The feedback system installed can only be replaced with an identical system. Retrofitting a
different system is not possible.
6.3.10 Holding brake
WARNING
Serious risk of injury!
The holding brake is not personal safety. If the brake is released then the rotor can be
moved without a remanent torque!
The motors are optionally available with an in­built holding brake free from backlash. The permanent magnet
brake blocks the rotor in de­energised state. The holding brakes are designed as standstill Brakes and
are not suited for repeated operational braking.
The holding brakes can be controlled directly by the servo terminal (no personal safety!). The brake voltage
is then switched off in the servo terminal — no additional wiring is required.
If the holding brake is not controlled directly by the servo terminal, additional circuitry (e.g. varistor) is
required. Consult our applications department beforehand.
The maximum number of brake cycles is 10 million.
Notice
Motor length
The motor length depends on the built­in holding brake, among other factors. It is not possi­
ble to fit one at a later date.
