Noise propagation path Measures
[1] [2] [3]
When devices such as instrument, receiver or sensor, which handle minute signals and are easily
affected by noise, or the signal wire of these devices, are stored in the same panel as the drive
units and the wiring is close, the device could malfunction due to airborne propagation of the noise.
In this case, take the following measures.
(a) Install devices easily affected as far away from the drive units as possible.
(b) Lay devices easily affected as far away from the signal wire of the drive unit as possible.
(c) Avoid laying the signal wire and power line in a parallel or bundled state.
(d) Insert a line noise filter on the input/output wire or a radio filter on the input to suppress the
noise radiated from the wires.
(e) Use a shield wire for the signal wire and power line, or place in separate metal ducts.
[4] [5] [6]
If the signal w ire is laid in parallel to the pow er line, or if it is bundled with the pow er line, the noise
could be propagated to the signal wire and cause malfunction because of the magnetic induction
noise or static induction noise. In this case, take the following measures.
(a) Install devices easily affected as far away from the drive unit as possible.
(b) Lay devices easily affected as far away from the signal wire of the drive unit as possible.
(c) Avoid laying the signal wire and power line in a parallel or bundled state.
(d) Use a shield wire for the signal wire and power line, or place in separate metal ducts.
[7]
If the power supply for the peripheral devices is connected to the power supply in the same system
as the drive units, the noise generated from the power supply unit could back flow over the power
line and cause the devices to malfunction. In this case, take the following measures.
(a) Install a radio filter on the power supply unit's power line.
(b) Install a power filter on the power supply unit's power line.
[8]
If a closed loop is created by the peripheral device and drive unit's grounding wire, a leakage
current could flow and cause the device to malfunction.
In this case, change the device grounding methods and the grounding place.

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 servo/spindle motor.
4. Wire the drive units and servo/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 servo/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 motor brake 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 servo/spindle motor.
7. Do not modify this unit.
8. The half-pitch connector (CN1A, 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.
