    What to do if SAJ VM1000B Controller shows overcurrent during acceleration?
    • K
      Kevin RogersAug 14, 2025
      If the SAJ Controller experiences overcurrent during acceleration, it might be due to several reasons. The output circuit of the AC Drive could be grounded or short-circuited, requiring you to eliminate external faults. Alternatively, the acceleration time may be too short, so try increasing it. If the startup operation is performed on a rotating motor, select rotational speed tracking restart or start the motor after it stops. Finally, the AC Drive model might be of too small power, in which case you should select an AC Drive with higher power.

    What to do if SAJ VM1000B Controller indicates overvoltage during deceleration?
    • O
      oneillstephenAug 17, 2025
      If the SAJ Controller shows overvoltage during deceleration, it could be due to several reasons. The input voltage might be abnormal, so turn the input power to the normal range. Also, an external force might be driving the motor during deceleration, so cancel the external force. The deceleration time may be too short, so increase the deceleration time. The braking unit and braking resistor might not be installed, so install them.

    What causes overcurrent at constant speed in SAJ Controller?
    • M
      Morgan DavisAug 21, 2025
      If the SAJ Controller experiences overcurrent at constant speed, it could be because the output circuit of the AC Drive is grounded or short-circuited, requiring you to eliminate external faults. Also, the AC Drive model might be of too small power, so select an AC Drive of higher power.

    Why does SAJ VM1000B Controller show overvoltage at constant speed?
    • H
      harmonjeremyAug 28, 2025
      If the SAJ Controller experiences overvoltage at constant speed, it could be due to the input voltage being abnormal; in this case, turn the input power to the normal range. Another possibility is that an external force drives the motor during deceleration, so cancel the external force.

    What to do if SAJ VM1000B displays undervoltage?
    • M
      Michael JeffersonSep 5, 2025
      If the SAJ Controller shows undervoltage, it might be due to an instantaneous power failure on the input supply, so reset the fault. Also, the input voltage might not be within the normal range, so adjust the input voltage to the normal range.

    Why SAJ VM1000B Controller shows buffer resistance overload?
    • B
      Brandon MillerSep 8, 2025
      If the SAJ Controller experiences buffer resistance overload, it is because the input voltage is not within the allowable range. Adjust the input voltage to the allowable range.
