How to fix Mitsubishi Electric FR-A800 speed when it does not accelerate to the command speed?
If the speed of your Mitsubishi Electric Inverter does not accelerate to the command speed, it may be due to a torque shortage. Try raising the torque limit. Also, increasing the capacity may help. If only P (proportional) control is performed, and the load is heavy, select PI control to prevent speed deviation.
What to do if Mitsubishi Electric Inverter motor does not rotate in vector control?
If your Mitsubishi Electric Inverter motor does not rotate in vector control, check the motor wiring. Set V/F control (set Pr. 80 "Motor capacity" or Pr. 81 "Number of motor poles" to "9999") and check the motor rotation direction. For SF-V5RU (1500 r/min series), set Pr. 19 "Base frequency voltage" to "170 V (340 V)" when the value is 3.7 kW or lower, and set it to "160 V (320 V)" when the value is higher, and set Pr. 3 "Base frequency" to "50 Hz". When a forward signal is input, rotation in the counterclockwise direction as viewed from the motor shaft direction is correct. Also, check the encoder specifications and the encoder type selection switch of differential/ complementary (Vector control compatible option). Check the wiring of encoder, and set Pr. 359 (Pr.852) "Encoder rotation di...
