Why is my SAJ VM600 module overheating?
If your SAJ DC Drive is overheating, it could be due to a high ambient temperature; lower the ambient temperature. Another reason may be that the air filter needs cleaning; clean the air filter.
What causes overvoltage at constant speed on SAJ DC Drives?
If you're experiencing overvoltage at a constant speed with your SAJ DC Drives, there are a couple of potential causes. First, the input voltage might be abnormal; turn the input power to the normal range. Second, an external force might be driving the motor during deceleration; cancel the external force.
What to do if the motor does not rotate after the SAJ DC Drives runs?
If the motor connected to your SAJ DC Drive isn't rotating after the AC Drive runs, the motor might be damaged; replace the motor. The motor cables might be abnormal; ensure the cable between the AC Drive and the motor is normal. The cable between the drive board and control board might be in poor contact; check this cable.
Why are the DI terminals disabled on my SAJ DC Drives?
If the DI terminals on your SAJ DC Drive are disabled, the parameters might be set incorrectly; check and reset the parameters in group F5. Alternatively, the external signal might be incorrect; reconnect the external signal cables.
What causes motor overload when using SAJ VM600 DC Drives?
If your motor is overloaded when using SAJ DC Drives, the parameter setting of F2.03 might not match the motor; set this parameter correctly. Also, the AC Drive model might be too small for the power demands; reduce the load and check the motor.
What to do if there is no display at power-on state on SAJ VM600 DC Drives?
If there's no display when you power on your SAJ DC Drive, the input power might be abnormal; check the input power. The control board might have a bad contact with the cable connected to the keypad; reconnect the cable.
