•
Do not get close to the mechanical equipment when the restart function is
enabled. Failure to comply may result in personal injury.
•
Do not touch the fan or the discharging resistor to check the temperature.
Otherwise, you may get burnt.
•
Signal detection must be performed only by qualied personnel during operation.
Failure to comply may result in personal injury or equipment damage.
•
Prevent dropping objects into the equipment during the drive running. Failure to
comply may result in damage to the equipment.
•
Do not start or stop the servo drive by turning on or off the contactor. Failure to
comply may result in equipment damage.
During
maintenance
•
Do not repair or maintain the servo drive at power-on. Failure to comply will result
in electric shock.
•
Repair or maintain the servo drive only after the CHARGE indicator on the servo
drive goes off. This allows for the residual voltage in the capacitor to discharge to
a safe value. Failure to comply will result in personal injury.
•
Repair or maintenance of the servo drive can be performed only by qualied
personnel. Failure to comply will result in personal injury or damage to the servo
drive.
1.2 General Precautions
1. Motor insulation test
Arrange for a qualied technician to perform an insulation test on the motor under the following conditions:
•
Before the motor is used for the rst time
•
When the motor is reused after being stored for a long time
•
During regular maintenance checks
This precaution detects poor insulation of the motor windings so that early actions can be taken to prevent
damage to the servo drive. The motor must be disconnected from the servo drive during the insulation test. A
500 V volt insulation tester is recommended for this test, and the insulation resistance must not be less than 5
MΩ.
