How to fix overcurrent during acceleration in SAJ VM600?
- C
  Crystal GarciaAug 20, 2025
  If your SAJ DC Drive experiences overcurrent during acceleration, there are several potential causes. First, the output circuit might be grounded or short-circuited; in this case, eliminate any external faults. Second, the acceleration time might be too short, so try increasing it. Third, starting the motor while it's rotating can cause this issue; select rotational speed tracking restart or wait until the motor stops before starting. Finally, the AC Drive model might be too small for the power demands; consider selecting an AC Drive with higher power.

What to do if my SAJ VM600 DC Drives show an overload?
- M
  Mr. Levi Butler Jr.Aug 22, 2025
  If your SAJ DC Drive shows an overload, it might be due to a load that is too heavy or a locked rotor on the motor. Try reducing the load and checking the motor. Also, the AC Drive model may be too small for the power demands; consider selecting an AC Drive with higher power.

Why am I getting overvoltage during deceleration on my SAJ DC Drives?
- S
  Stacey NelsonAug 25, 2025
  If you're experiencing overvoltage during deceleration with your SAJ DC Drives, several factors could be at play. First, check if the input voltage is abnormal and ensure it's within the normal range. Second, an external force might be driving the motor during deceleration; cancel any such external force. Third, the deceleration time might be too short, so increase it. Lastly, the braking unit and braking resistor might not be installed; install them if they are missing.

How do I resolve overcurrent during deceleration in SAJ DC Drives?
- S
  Sara ButlerAug 26, 2025
  If your SAJ DC Drive is experiencing overcurrent during deceleration, there are a couple of potential reasons. First, the output circuit of the AC Drive could be grounded or short-circuited; eliminate any external faults. Second, the deceleration time might be too short; increase the deceleration time.

Why is the motor noise too loud on my SAJ VM600?
- F
  Frank CarrAug 27, 2025
  If the motor connected to your SAJ DC Drive is making excessive noise, it could be due to motor damage or mechanical failure; in this case, replace the motor or clear the mechanical fault. Alternatively, the carrier frequency setting might be too small; increase the carrier frequency appropriately.

How to reduce interference in SAJ VM600 DC Drives?
- C
  courtney25Aug 29, 2025
  If your SAJ DC Drive is experiencing interference, it could be due to several reasons. The carrier frequency setting might not be suitable, so try reducing it. Ensure the AC Drive and the motor are effectively grounded and separated from the ground of any peripheral devices. If the wire between the AC Drive and the motor is too long, install an output reactor or reduce the wire distance.

What causes overvoltage during acceleration in SAJ VM600 DC Drives?
- L
  Lisa LopezAug 31, 2025
  If your SAJ DC Drive shows overvoltage during acceleration, first, ensure the input voltage is normal. Second, if an external force drives the motor during acceleration, cancel it. Third, if the acceleration time is too short, increase it. Fourth, if the braking unit and braking resistor are not installed, install them.

Why does my SAJ VM600 DC Drives switch trip?
- B
  Brenda CoffeySep 2, 2025
  If your SAJ DC Drive experiences a switch trip, it could be due to a few reasons. First, you might have installed a leakage switch or an air switch that's overloaded; replay the leakage switch or replay the larger capacity air switch. Second, the input power of the AC Drive might be abnormal; eliminate whether the input power is shorted.

What causes overcurrent at constant speed in SAJ VM600?
- P
  Patricia RodriguezSep 4, 2025
  If your SAJ DC Drive reports overcurrent at a constant speed, the output circuit of the AC Drive might be grounded or short-circuited; eliminate any external faults. Also, the AC Drive model might be too small for the power demands; select an AC Drive with higher power.

What to do if SAJ DC Drives show undervoltage?
- C
  Christopher MasonSep 6, 2025
  If your SAJ DC Drive shows undervoltage, it could be due to a few reasons. An instantaneous power failure might be occurring on the input supply; reset the fault. The input voltage might not be within the normal range; adjust the input voltage to the normal range.
