66 Item to be confirmed Confirmation content Power wiring confirmation Check whether the input power voltage is consistent with the voltage of the inverter. Confirm that the circuit breaker has been connected to the power supply circuit, and the power cables are correctly connected to the input terminals (R, S, T) of the inverter. Make sure that the inverter and motor are properly grounded. Motor wiring confirmation Confirm that the motor is correctly connected to the output terminals (U, V, W) of the inverter, and the motor wiring is secured.
Confirmation of braking unit and braking resistor Make sure that the braking resistor and braking unit are properly connected (use the dynamic braking resistor if necessary during operation). Control terminal wiring confirmation Check whether the control terminals of the inverter are correctly and reliably connected to other controls. Control terminal status confirmation Make sure that the control terminal circuit of the inverter is disconnected to prevent operation upon powering on.
Check wiring of the PG card and the encoder When closed-loop control is required, it is required to check wiring of the PG card and the encoder for correctness and reliability Mechanical load confirmation Confirm that the machinery is in the no-load state and free of danger in operation. State Display Description During normal operation The output frequency is 0 and the given frequency is 0 The digital setting 0Hz is displayed by default Protection Protection code in character or Exx format The protection code is displayed in the protection status. See the protection measures in Chapter 6.
