A90 series Inverter User Guide Status combination of run command input is in terminal control mode: Change it to keypad control mode. Setting reference input frequency= 0: Increase reference input frequency. Power supply is abnormal or control circuit fails. When control terminals RUN and F/R are ON, motor does not run. Command channel is not terminal control: Check function setting code F00.02 Command channel setting. Free stop terminal and COM closed: Disconnect the free stop terminal from COM. control switch failure: check the control switch and the relevant wiring is correct, whether there is a broken line exists Reference input frequency is set to 0:
Increase the reference input frequency. The digital input terminal is selected for the inverter to enable the terminal to be inactive: Closed to enable the terminal. The motor can only rotate in one direction Reverse rotation is disabled: When the reverse inhibit code parameter F00.21 is set to 1, the motor is not allowed to reverse. The motor rotates in the opposite direction Inverter output phase sequence and the motor input is not consistent: 10 minutes in the power off, and the motor stationary state, any exchange of two motor connections can change the direction of rotation of the motor. 6.2.3 Motor acceleration time is too long Set the acceleration time too long:
Please confirm the acceleration time code parameter 。 Too heavy load: Make sure the load is jammed, or if the motor does not match the load. Before running the motor is rotating: Please use the start DC brake, or the speed tracking start. 6.2.4 The motor deceleration time is too long When the energy consumption brake is active Brake resistor resistance is too large, energy consumption Brake power is too small to extend the deceleration time: Please press the guide to select the appropriate brake resistor. Set the deceleration time too long: Please confirm the deceleration time code parameter. Built-in brake unit of the inverter, not activated Power consumption Brake function:
Check whether F15.30 is a 1 energy brake effective. When stall protection is active Overvoltage stall protection operation, the DC bus voltage exceeds the overvoltage stall voltage (F07.07),The output frequency remains unchanged,When the DC bus voltage is lower than F07.07, The output frequency continues to decline,This extends the deceleration time. The set deceleration time is too long. Please confirm the deceleration time code parameter.
6.2.5 Electromagnetic interference and radio frequency interference When the inverter is running, because the inverter work in the high-frequency switching state, the control equipment will produce Electromagnetic interference and RF interference, the following measures can be taken: 36
