INVT SV-DB100 Series, Operation Manual

Page: 26 / 171

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.
The electromagnetic brake uses 24V power supply which
should be provided by the user. Do not share it with the
control signal power supply. pow
Do not disconnect the short circuit wire between B2 and
B3 unless an external regenerative braking resistor is
used.
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.
Be sure to ground the servo drive with proper techniques
to avoid the accident of electrical shock.
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.
Check whether the phase number/voltage grade of the AC
power supply are consistent with those identification on the
nameplate of the drive.
Do not use this electromagnetic contactor to start/stop the
servo drive.
Non-fuse breaker or leakage switch.
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.
