Correctly and securely wire the wires. Reconfirm the connections for mistakes and the terminal
screws for tightness after wiring. Failing to do so may lead to run away of the servomotor.
After wiring, install the protective covers such as the terminal covers to the original positions.
Do not install a phase advancing capacitor, surge absorber or radio noise filter (option FR-BIF)
on the output side of the servo amplifier.
Correctly connect the output side (terminal U, V, W) and ground. Incorrect connections will lead
the servomotor to operate abnormally.
Do not connect a commercial power supply to the servomotor, as this may lead to trouble.
Do not mistake the direction of the surge absorbing diode
installed on the DC relay for the control signal output of brake
signals, etc. Incorrect installation may lead to signals not being
output when trouble occurs or the protective functions not
Do not connect or disconnect the connection cables between
each unit, the encoder cable or PLC expansion cable while the
power is ON.
Securely tighten the cable connector fixing screws and fixing mechanisms. Insufficient fixing may
lead to the cables combing off during operation.
Do not bundle the power line or cables.
(5) Trial operation and adjustment
Confirm and adjust the program and each parameter before operation. Unpredictable
movements may occur depending on the machine.
Extreme adjustments and changes may lead to unstable operation, so never make them.
When using the absolute position system function, on starting up, and when the Motion
controller or absolute value motor has been replaced, always perform a home position return.
