BECKHOFF AM2000 - Manual (Page 10)

I.5.6 Insulation material class
The motors come up to insulation material class F according to DIN 57530.
I.5.7 Vibration class
The motors are made to vibration class N according to DIN ISO 2373.
I.5.8 Connection method
The motors are fitted with rectangular connectors for power supply and resolver signals.
The mating connectors are not part of the delivery package. We can supply preassem-
bled resolver and power leads (Þ II.2.1).
I.5.9 Feedback unit
The motors are equipped with two-pole hollow-shaft resolvers as standard. As an option,
the motors are available with built in single- (ECNxx13) or multiturn (EQNxx25)
EnDat-encoders.
Type designation singleturn: AM2xxx-xxxx-S3-1313 (AM227 with S3-1113)
Type designation multiturn: AM2xxx-xxxx-S3-1325 (AM227 with S3-1125)
The motor length changes when an encoder is mounted. Retrofitting is not possible.
I.5.10 Holding brake
The motors are optionally available with a holding brake.
Type designation: AM2xxx-0001
A permanent magnet brake (24V DC) is integrated into the G-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 remanent torque, the operation is free from backlash! The motor
length increases when a holding brake is mounted.
The holding brake can be controlled directly by AX2000-servoamplifier (no personal
safety !), the winding is suppressed in the servoamplifier — additional circuitry is not
required.
If the holding brake is not controlled directly by the servoamplifier, an additional wiring
(e.g. varistor) 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.
