NOTES ON USE
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.
S Make sure the motor is stopped when carrying out maintenance, inspection or wiring.
S Connect 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.
S If 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.
S Before 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.
RECEIVING
S Do not install or operate any inverter which is damaged or has missing
parts.
Failure to observe this caution may result in personal injury or equipment damage.
