How to troubleshoot continuous overcurrent in Lenze Inverter?
If the Lenze Inverter shows a continuous overcurrent inside the device, you should: * Check the motor and wiring for any short circuits. * Inspect the brake resistor and its wiring. * Verify the motor circuit's connection (delta or star). * Ensure the motor data settings are correct.
What to do if Lenze Inverter shows device utilization (Ixt) too high?
If your Lenze Inverter displays an error indicating the device utilization (Ixt) is too high, consider the following: * Verify the drive sizing is appropriate for the application. * Reduce the maximum overload current of the inverter (parameter 0x6073). * For applications with high mass inertias, reduce the maximum overload current of the inverter (0x6073) to 150%.
What to do if Lenze I55BE230F10V1000LS has short circuit or earth leakage on motor side?
If your Lenze Inverter reports a short circuit or earth leakage on the motor side, take these steps: * Inspect the motor cable for damage. * Consider the length of the motor cable. * Use a shorter or lower-capacitance motor cable.
How to fix Lenze Inverter power section overtemperature?
If your Lenze Inverter is experiencing a power section overtemperature issue, try the following: * Check the mains voltage. * Ensure the device has sufficient cooling by checking the heatsink temperature (0x2D84:001). * Clean the fan and ventilation slots, and replace the fan if needed. * Reduce the switching frequency (0x2939).
What to do if Lenze I55BE230F10V1000LS shows i²*t overload (thermal state)?
If the Lenze Inverter indicates an i²*t overload (thermal state), you can try the following: * Verify the drive sizing is adequate. * Inspect the machine/driven mechanics for excessive load. * Check the motor data settings. * Reduce the values for slip compensation (0x2B09:001, 0x2B09:002) and oscillation damping (0x2B0A:001, 0x2B0A:002).
How to resolve DC bus overvoltage on Lenze Inverter?
If the Lenze Inverter displays a DC bus overvoltage error, you can: * Reduce the dynamic performance of the load profile. * Check the mains voltage. * Check the settings for the brake energy management.
How to troubleshoot DC-bus undervoltage on Lenze Inverter?
If the Lenze Inverter shows a DC-bus undervoltage, you should: * Check the mains voltage. * Check the fuses. * Check the DC-bus voltage (0x2D87). * Check the mains settings.
