Wiring
Caution

Wiring connections must be secure.
Bodily injury could otherwise result.

Wiring should be completed based on the Wiring Diagram or the User Manual.
Electric shock or fire could otherwise result.

Wiring should follow electric equipment technical standards and indoor wiring
regulations.
An electrical short or fire could otherwise result.

Do not connect a commercial power supply to the U, V or W terminals of the servo
motor.
Fire or damage to the device could otherwise result.

Install a safety device such as a breaker to prevent external wiring short-circuits.
Fire could otherwise result.

Do not bind or band the power cable, input/output signal cable and/or encoder cable
together or pass through the same duct or conduit.
This action will cause faulty operation.

Must add the surge absorbing diode if inductive load as relay connect to the control
signal output of the amplifier. Please take care of polarity of the diode that will be
cause of failure.

Do not connect DC90V or AC power to the DC24V Brake of the servo motor. Also, do
not connect AC400V to the AC200V Fan of the servo motor.
An electrical short or fire could otherwise result.

Please design a sequence that included braking delay time because the
surge-absorbing component for the relay of holding brake of the servo motor gives
braking delay time.
Injury or load falling could otherwise result.
Mandatory

Install an external emergency stop circuit that can stop the device and cut off the power
instantaneously. Install an external protective circuit to the amplifier to cut off the power
from the main circuit in the case of an alarm.
Motor runaway, bodily injury, burnout, fire and secondary damages could otherwise
result.
