DANGER
1. Wiring work must be done by a qualified technician.
2. Wait at least 15 minutes after turning the power OFF and check the voltage
with a tester, etc., before starting wiring. Failure to observe this could lead to
electric shocks.
3. Securely ground the drive units and spindle motor.
4. Wire the drive units and spindle motor after installation. Failure to observe this
could lead to electric shocks.
5. Do not damage, apply forcible stress, place heavy items on the cables or get
them caught. Failure to observe this could lead to electric shocks.
6. Always insulate the power terminal connection section. Failure to observe
this could lead to electric shocks.
CAUTION
1. Correctly and securely perform the wiring. Failure to do so could result in
runaway of the spindle motor or injury.
2. Do not mistake the terminal connections.
Failure to observe this item could lead to ruptures or damage, etc.
3. Do not mistake the polarity ( + ,
- ). Failure to observe this item could lead to
ruptures or damage, etc.
4. Do not mistake the direction of the diodes for the surge absorption installed
on the DC relay for the general-purpose output and contactor (magnetic
contactor) control. The signal might not be output when a failure occurs.

5. Electronic devices used near the drive units may receive magnetic
obstruction. Reduce the effect of magnetic obstacles by installing a noise
filter, etc.
6. Do not install a phase advancing capacitor, surge absorber or radio noise
filter on the power line (U, V, W) of the spindle motor.
7. Do not modify this unit.
8. The half-pitch connector (CN10, etc.) on the front of the drive units have the
same shape. If the connectors are connected incorrectly, faults could occur.
Make sure that the connection is correct.
9. When grounding the motor, connect to the protective grounding terminal on
the drive units, and ground from the other protective grounding terminal.
(Use one-point grounding) Do not separately ground the connected motor
and drive unit as noise could be generated.
