NOTES ON USE
WARNING
The SS5 motor is a synchronous motor equipped with a built-in, high performance magnet as a rotor.
The SS5 motor terminals continue to produce high voltage whenever the motor is rotating even if
inverter power is OFF. Observe the following when hadling the inverter.
SMake sure the motor is stopped when carrying out maintenance, inspection or wiring.
SConnect a low-voltage manual starter to the inverter output side when the motor is rotated
by the load even if the inverter power is OFF.
CAUTION
SIf using a motor with a PG, be sure to confirm the safety and adjust the PG zero-pulse be-
fore starting any operation.
Failure to observe this caution may cause the torque to be insufficient, which may result in the
following motor malfunctions:
•The motor is pulled in the direction of the load.
•The motor rotates in reverse.
•The motor does not rotate.
•The motor suddenly accelerates.
SBefore starting operation, be sure to set the motor constants according to the motor name-
plate values.
Failure to observe this caution may cause torque insufficiency, which result in motor malfunc-
tions:
•The motor is pulled in the direction of the load.
•The motor rotates in reverse direction.
•The motor does not rotate.
•The motor is suddenly accelerated.

OPERATION
WARNING
(Ref. page)
SOnly turn ON the input power supply after replacing the front cover. Do not
remove the cover while current is flowing.
Failure to observe this warning can result in an electric shock. 38................
SWhen the retry function (L5-02) is selected, do not approach the inverter
or the load, since it may restart suddenly after being stopped.
(Construct machine system, so as to assure safety for personnel, even if the
inverter should restart.)
Failure to observe this warning can result in personal injury. 38.................
SSince the stop button can be disabled by a function setting, install a sepa-
rate emergency stop switch.
Failure to observe this warning can result in personal injury. 38.................
SIf an alarm is reset with the operation signal ON, the inverter restarts auto-
matically. Only reset the alarm after verifying that the operation signal is
OFF.
