8.10 Motor connection with brake (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. 25) 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 flashovers in the motor winding.
— Only install motors with insulation class F (acc. to IEC60085) or above
— Only install cables that meet the requirements on p.28 and p.53.
CAUTION
No functional safety! Serious injury could result when a suspended load
is not properly blocked.
l
An additional mechanical brake is required for functional safety, which
must be safely operated, e.g. via the Safety Card S1-2 (see p. ).
Cable length £ 25 meters
Cable length >25 meters
With long motor cables leakage currents endanger the output stage of the S300. For
cable lengths above 25m up to max. 50m, a motor choke 3YLor 3YLN (see accessories
manual) must be wired into the motor cable, close to the amplifier.
