Precautions
During
running
•
All peripheral devices must be connected properly according
to the circuit wiring instructions provided in this manual.
Failure to comply will result in accidents
•
Cover the controller properly before power-on to prevent
electric shock.
•
Do not open the controller’s cover after power-on. Failure to
comply may result in electric shock.
•
Do not touch the controller and peripheral circuits with wet
hand. Failure to comply may result in electric shock.
•
Do not touch any I/O terminal of the controller. Failure to
comply may result in electric shock.
•
The controller performs safety detection on external strong
power circuits automatically at the beginning of power-on.
Do not touch the U, V, W terminals of the controller or the
motor terminals at the moment. Failure to comply may result
in electric shock.
•
Do not touch the fan or the discharging resistor to check the
temperature. Failure to comply will result in personal burnt.
•
Signal detection must be performed only by qualied
personnel during operation. Failure to comply will result in
personal injury or damage to the controller.
•
Do not touch the rotating part of the motor during the motor
auto-tuning or running. Failure to comply will result in
accidents.
•
Check that the following requirements are met:
•
The voltage class of the power supply is consistent with the
rated voltage class of the controller.
•
The input terminals (R, S, T) and output terminals (U, V, W)
are properly connected.
•
No short-circuit exists in the peripheral circuit.
•
The wiring is secured.
Failure to comply will result in damage to the controller.
•
For synchronous motor, ensure that motor auto-tuning is
performed successfully. Perform trial running before resuming
the steel rope so as to make the motor run properly.
•
Avoid objects falling into the controller when it is running.
Failure to comply will result in damage to the controller.
•
Do not perform the voltage resistance test on any part of the
controller because such test has been done in the factory.
Failure to comply may result in accidents.
•
Do not change the default settings of the controller. Failure
to comply will result in damage to the controller.
•
Do not start/stop the controller by turning on or off the
contactor. Failure to comply will result in damage to the
controller.
