Motor and holding brake connection (X9)

Together with the motor supply cable and motor winding, the power output of the servo
amplifier forms an oscillating circuit. Characteristics such as cable capacity, cable length,
motor inductance, frequency and voltage rise speed (see Technical Data, p. 28) deter-
mine the maximum voltage in the system.
The dynamic voltage rise can lead to a reduction in the motor's operating life and, on
unsuitable motors, to flash overs in the motor winding.
— Only install motors with insulation class F (acc. to IEC 60085) or above
— Only install cables that meet the requirements on p.31 and p.61.
CAUTION
The brake function does not ensure functional safety! Danger by falling
load (in case of suspended load, vertical axes). An additional mechanical
brake is required for functional safety, which must be safely operated,
e.g. via the Safety Card S1-2 (see p. 155).
Wiring with cable length £ 25m
Wiring with cable length >25m
With long motor cables leakage currents endanger the output stage of the servo amplifier.
For cable lengths above 25m up to max. 50m, the motor choke 3YL or 3YLN (see acces-
sories manual) must be wired into the motor cable, close to the amplifier.
