During
DANGER
running
• Wiring must be performed only by qualified personnel under
instructions described in this manual. Failure to comply may
result in unexpected accidents.
• A circuit breaker must be used to isolate the power supply and
the controller. Failure to comply may result in a fire.
• Ensure that the power supply is cut off before wiring. Failure to
comply may result in electric shock.
• Tie the controller to ground properly according to the standard.
Failure to comply may result in electric shock.
• Never connect the power cables to the output terminals (U, V,
W) of the controller. Pay attention to the marks of the wiring
terminals and ensure correct wiring. Failure to comply will result
in damage to the controller.
• Ensure that the cabling satisfies the EMC requirements and
the local codes. Use wire sizes recommended in the manual.
Failure to comply may result in accidents.
• Never connect the regen. resistor between the DC bus
terminals (+) and (-). Failure to comply may result in a fire.
• Use the shielded cable for the encoder, and ensure that the
shield is reliably grounded at one end.
• Use a twisted cable with twisted distance of 20−30 mm as the
communication cable, and ensure that the shield is reliably
grounded.
• 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 qualified personnel
during operation. Failure to comply will result in personal injury
or damage to the controller.
