CAUTION
When coupling with the synchronization encoder or servomotor shaft end, do not apply
impact such as by hitting with a hammer. Doing so may lead to detector damage.
Do not apply a load larger than the tolerable load onto the servomotor shaft. Doing so may
lead to shaft breakage.
When not using the unit for a long time, disconnect the power line from the control unit or
servo amplifier.
Place the control unit and servo amplifier in static electricity preventing vinyl bags and store.
When storing for a long time, please consult our sales representative.
(4) Wiring
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
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 (terminals U, V, W). 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 functioning.
Do not connect or disconnect the connection cables
between each unit, the encoder cable or sequence ex-
pansion 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
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 controller or
absolute value motor has been replaced, always perform a home position return.
