General
1.8.7
Vibration class
The motors are made to vibration class N according to DIN EN 60034-14.
1.8.8
Connection method
The motors are equipped with angular connectors (AKM1: straight connectors at cable ends) for
power supply and feedback signals .
The mating connectors are not part of the delivery package. We can supply preassembled resolver
and power cables. On page 16 you will find notes on the cable materials.

The motor length depends on the mounted feedback unit. Retrofitting is not possible.

Holding brake
The AKM2-AKM7 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. The holding brakes are designed as standstill brakes and are not suited for
repeated operational braking. If the brake is released then the rotor can be moved without a rema-
nent torque. The motor length increases when a holding brake is mounted.
The holding brake can be controlled directly by SERVOSTAR-servo amplifier (no personal safety !),
the winding is suppressed in the servo amplifier — additional circuitry is not required.
If the holding brake is not controlled directly by the servo amplifier, an additional wiring (e.g. varis-
tor) is required. Consult our applications department beforehand.
A personal safe operation of the holding brake requires an additional contact (normally opened) in
the braking circuit and an anti-surge-device (e.g. Varistor) for the brake.
