(6) Trial operation and adjustment
CAUTION
 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
servo motor.
 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 servo motor to operate abnormally.
 Do not connect a commercial power supply to the servo motor, 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 functioning.
 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 coming off during operation.
 Do not bundle the power line or cables.
CAUTION
 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.
 Before starting test operation, set the parameter speed limit value to the slowest value,
and make sure that operation can be stopped immediately by the forced stop, etc. if a
hazardous state occurs.
