z 4. During the operation of the servo driver, keep items from falling into
the equipment. Otherwise, it may damage the equipment!
z 5. Do not start and stop the servo driver by connecting and disconnecting
the contactor. Otherwise, it may damage the equipment!
1.1.7 During Repair
Danger
z Do not repair and maintain the equipment with power connection.
Otherwise there will be danger of electric shock!
z be sure to conduct repair and maintenance after the charge LED indictor
of the servo driver is OFF. Otherwise, the residual charge on the
capacitor may cause personal injury!
z The servo driver shall be repaired and maintained only by the qualified
person who has received professional training. Otherwise, it may cause
personal injury or equipment damage!
1.2 Precautions
1.2.1 Motor Insulation Inspection
When the motor is used for the first time, or when the motor is reused after
being kept, or when periodical inspection is performed, it shall conduct motor
insulation inspection so as to avoid damaging the driver because of the
insulation failure of the motor windings. The motor wires must be
disconnected from the driver during the insulation inspection. It is
recommended to use the 500V megameter, and the insulating resistance
measured shall be at least 5MΩ.
1.2.2 Thermal Protection of the Motor
If the rated capacity of the servo motor does not match those of the driver,
especially when the rated power of the driver is higher than the rated power of
the motor, the relevant motor protection parameters in the driver shall be
adjusted, or thermal relay shall be mounted to protect the motor.
1.2.3 Motor Heating and Noise
Since the output voltage of servo driver is PWM wave and contains certain
