For wiring details, see the smartris Servo Drive Unit Maintenance Manual (No. DM1802E).
DANGER
- Do not handle the unit when cables are energized. Be sure to turn off the power when working
on the unit; otherwise, electric shock may result.
- Follow instructions in the Maintenance Manual when connecting power cables; otherwise, elec-
tric shock or fire may result.
- Do not forcibly bend, pull, or clamp the power cable and lead wires; otherwise, electric shock or
fire may result.
- Correctly ground the grounding bolt; otherwise, electric shock may result.
CAUTION
- When wiring, follow the facility's regulations and electrical codes, in order to prevent burning,
electric shock, injury, and fire.
- The motor is not equipped with a protection device. However, it is compulsory to install an over-
load protector according to facility electrical codes. It is recommended to install other protective
devices (earth leakage breaker, etc.), in addition to an overload protector to prevent burning,
electric shock, injury, and fire.
- Do not touch the terminals when measuring insulation resistance; otherwise, electric shock may
result.
- Changing the phase sequence of the U, V, W wiring will prevent this product from operating and
may cause malfunctions. Always perform wiring in the designated phase sequence.
- For motor, do not energize the brake coil when the motor is stopped. Otherwise coil burnout fire
may result. Also, mistaken wiring could damage the rectifier.
- Long cables cause large voltage drops. Select cables with appropriate diameter so that the volt-
age drop will not be greater than 2%.
