How to fix IP54 FAN Trip on LSIS DC Drives?
To resolve an IP54 FAN Trip error on LSIS DC Drives, check the following: - Ensure the internal fan connector is connected. - Verify the internal fan PCB board’s power connector is connected.
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.
What does In Phase Open mean on LSIS DC Drives?
An In Phase Open error on LSIS DC Drives can occur if the magnetic contactor on the input side has a connection fault; check the magnetic contactor on the input side. It may also be caused by faulty input wiring, so check the input wiring. Finally, the DC link capacitor may need replacement; contact the retailer or the LSIS customer service center.
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 does Out Phase Open mean on my LSIS DC Drives?
An Out Phase Open error on LSIS DC Drives suggests a connection fault with the magnetic contactor on the output side; check the magnetic contactor on the output side. It could also indicate faulty output wiring, which also needs to be checked.
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.
