Why is my LSIS DC Drives showing Over Current2?
An overcurrent error in LSIS DC Drives may be due to a short circuit in the output wiring; check the output wiring. Alternatively, there might be a fault with the electronic semiconductor (IGBT). If this is the case, do not operate the inverter and contact the retailer or the LSIS customer service center.
What to do if the CPU indicator is flashing in 1 second intervals, and the ERROR indicator is flashing in 2 second intervals on my LSIS Inverter?
First, check the communication link where the LAN cable is connected and ensure that the LINK indicator is turned on. Next, check the LAN cable and ensure that it is properly connected to the link port. Also, check to ensure that the communication module’s device name and [COM-22] Telegram Mode parameter settings match the network configuration at the PLC. Finally, ensure that the IP address assigned to the communication module is not already used by other devices on the same network.
What to do if ERROR and CPU indicators are both turned off on my LSIS SV-iS7 Inverter?
This could indicate that power is not being supplied to the communication module. Correctly install the communication module to the inverter. Also, check the connector pins on the communication module for bends or other defects.
What to do if ERROR indicator and CPU indicator are flashing synchronously in 1 second intervals on my LSIS Inverter?
Check the connector pins on the communication module for bends or other defects. If the problem persists after taking the measures listed above, it may indicate that the hardware is malfunctioning.
What to do if the LSIS DC Drives show a constant red light?
If the LSIS DC Drive shows a constant red light, it could be due to communication issues. Ensure the communication and power supply cables are separated. Also, verify the status of the connected nodes.
Why is the red light on my LSIS DC Drives?
If the LSIS DC Drive shows a constant red light, it indicates that communication is not established. Check if the communication cable and power supply cable are separated. Power cycle the inverter (turn it off and then on again).
How can I resolve an Over Heat error on my LSIS DC Drives?
An 'Over Heat' error on LSIS DC Drives can stem from several causes: a problem with the cooling system (check for obstructions in the air inlet, outlet, or vent), an inverter cooling fan that has been operating for an extended period (replace the cooling fan), or an ambient temperature that is too high (ensure it's below 50 ?).
What to do if LSIS DC Drives display Low Voltage?
If your LSIS DC Drives show a low voltage error, first determine if the input voltage is below the specified value. It could also be that a load greater than the power capacity is connected to the system; in this case, increase the power capacity. Finally, a faulty magnetic contactor connected to the power source can cause this; replace the magnetic contactor.
How to troubleshoot E-Thermal errors in LSIS DC Drives?
An E-Thermal error in LSIS DC Drives indicates overheating. This can occur if the motor has overheated, so reduce the load or operation frequency. The inverter load might be greater than the rated capacity, necessitating a replacement with a higher-capacity model. Also, the set value for electronic thermal protection may be too low, so set an appropriate electronic thermal level. Finally, if the inverter has been operated at low speed for a long time, replace the motor with one that supplies extra power to the cooling fan.
Why is my LSIS DC Drives showing Over Current1?
The LSIS DC Drives might display an overcurrent error if the acceleration/deceleration time is too short relative to the load inertia. Try increasing the acceleration/deceleration time. It could also be that the inverter load is greater than its rated capacity, requiring you to replace the inverter with a model of increased capacity. Also, check if the inverter supplied an output while the motor was idling and operate the inverter after the motor has stopped or use the speed search function (CON-70). Finally, the mechanical brake of the motor might be operating too fast; in that case, check the mechanical brake.
