If your CHINSC ELECTRIC DC Drive trips the MCCB after power-on, it could be due to earth or shorted inputs of the supply; troubleshoot the issue. It may also be due to rectifier breakdown, or a wrong connection between the power line and motor line; in this case, seek service.
Why CHINSC ELECTRIC SVF-MN DC Drives shows over-current during Deceleration?
If your CHINSC ELECTRIC DC Drive displays an over-current error during deceleration, it might be due to a too short deceleration time. Try prolonging the deceleration time. Alternatively, the AC supply voltage may be low, so consider using a suitable dynamic braking kit. If the drive power is too small, select a high-power drive.
What to do if CHINSC ELECTRIC SVF-MN shows over-current in constant speed operation?
If your CHINSC ELECTRIC DC Drive shows an over-current error during constant speed operation, it may be due to a sudden change of load or an abnormal load. Check the load or reduce the sudden change of load. It could also be caused by a low AC supply voltage, so check the AC input power supply. If the drive power is too small, select a high power drive.
Why CHINSC ELECTRIC SVF-MN DC Drives shows over-voltage during Deceleration?
If your CHINSC ELECTRIC DC Drive displays an over-voltage error during deceleration, it could be due to a too short deceleration time; prolong the deceleration time. It may also be caused by too big load inertia; use a big dynamic braking kit. Finally, check the AC supply voltage because the abnormal input voltage can cause this error.
What causes over-voltage during Acceleration in CHINSC ELECTRIC SVF-MN?
If your CHINSC ELECTRIC DC Drive displays an over-voltage error during acceleration, check the input power supply, as the problem may be due to abnormal input voltage.
How to fix IGBT module’s shorted error in CHINSC ELECTRIC SVF-MN?
If your CHINSC ELECTRIC DC Drive displays an IGBT module shorted error, it could be due to several reasons. The acceleration time may be too short, so prolong the Acc time. Internal damage to the IGBT is another possibility, so seek service. Interference may also cause the malfunction; check peripheral equipment for strong interference. Poor grounding can also be a factor, so seek service.
What causes EEPROM R/W fault in CHINSC ELECTRIC SVF-MN DC Drives?
If your CHINSC ELECTRIC DC Drive displays an EEPROM R/W fault, it could be due to a R/W fault of control parameters; press STOP/RST to reset and seek service. It may also be due to damaged EEPROM, in this case, seek service.
What to do if CHINSC ELECTRIC SVF-MN shows temperature sensor fault?
If your CHINSC ELECTRIC DC Drive displays a temperature sensor fault, it indicates that the temperature sensor is off line or has a fault. Power off, and check the frequency inverter temperature wire for looseness, then seek service.
What to do if CHINSC ELECTRIC DC Drives doesn’t display after power-on?
If your CHINSC ELECTRIC DC Drive doesn’t display after power-on, the drive's input supply may be inconsistent with the rated voltage. Check with a multi-meter and troubleshoot the issue. It could also be a sign of a blasted 3-phase rectifier bridge, or that the drive cannot charge, in which case you should seek service.
What to do if CHINSC ELECTRIC SVF-MN shows DC Bus under-voltage?
If your CHINSC ELECTRIC DC Drive displays a DC Bus under-voltage error, check the AC supply voltage, as the problem may be due to low AC supply voltage.
