Check whether the phase number/voltage grade
of the AC power supply are consistent with those
identification on the nameplate of the drive.
z
Non-fuse breaker or leakage switch.
z
Be sure to fit a noise filter.
z
Do not use this electromagnetic contactor to
start/stop the servo drive.
z
Please fit an AC reactor.
z
Do not disconnect the short circuit wire between B2
and B3 unless an external regenerative braking
resistor is used.
z
When an external regenerative braking resistor is
used, disconnect the short circuit wire between B2
and B3, and connect it according to the dashed in
the figure.
z
Be sure to ground the servo drive with proper
techniques to avoid the accident of electrical
shock.
z
Please set a circuit which can activate the
electromagnetic brake not only through the servo
drive but also through the external emergency stop
device. Please refer to section 4.6.
z
The electromagnetic brake has no polarity.
z
The electromagnetic brake uses 24V power supply
which should be provided by the user. Do not share
it

The distance between the servo motor and the servo drive should not exceed 20m. Keep a
distance of at least 30cm between the encoder wire, motor cable and power cable.

Correctly connect to output U, V, and W of the drive
according to the phase sequence of the motor cable
of the servo motor. Wrong phase sequence will
cause drive fault.
