What to do if my LSIS DC Drives show Over Load?
If your LSIS DC Drives indicate an overload, it could be due to the load exceeding the motor's rated capacity. Ensure the motor and inverter have appropriate capacity ratings. Alternatively, the overload trip level (PRT-21) might be set too low; in that case, increase its value.
How to troubleshoot an LSIS DC Drives that is not turning on?
If your LSIS DC Drive is off, first ensure the power supply is energized. Check if the communication board is installed on the inverter and verify that the inverter is turned on.
What to do if LSIS DC Drives are flickering with 200ms?
If your LSIS DC Drive is flickering with a 200ms interval, it suggests an abnormal interface communication issue between the communication board and the inverter. Make sure the communication cable and power supply cable are separated. Turn off the inverter, and then turn it back on.
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).
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.
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 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 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.
