CAUTION
(2) Wiring
Correctly and securely perform the wiring. Failure to do so could lead to runaway of the
servomotor.
Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of
the servo drive unit.
Correctly connect the output side (terminals U, V, W). Failure to do so could lead to abnormal
operation of the servomotor.
Do not directly connect a commercial
power supply to the servomotor. Failure
to observe this could result in a fault.
When using an inductive load such as a
relay, always connect a diode as a noise
measure parallel to the load.

When using a capacitance load such as a lamp, always connect a protective resistor as a
noise measure serial to the load.
Do not reverse the direction of a diode which connect to a DC relay for the control output
signals to suppress a surge. Connecting it backwards could cause the drive unit to malfunction
so that signals are not output, and emergency stop and other safety circuits are inoperable.
Do not connect/disconnect the cables connected between the units while the power is ON.
Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could
cause the cable to fall off while the power is ON.
When using a shielded cable instructed in the connection manual, always ground the cable with
a cable clamp, etc.
Always separate the signals wires from the drive wire and power line.
Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to
the system.
