How to fix DC bus overvoltage on Lenze Inverter?
To address DC bus overvoltage, consider the following: * Reduce dynamic performance of the load profile. * Check the mains voltage. * Review the settings for braking energy management. * Connect a brake resistor to the power unit and activate the integrated brake chopper by setting P706.01 = 0 (brake resistance).
What to do if my Lenze I55BE F shows a continuous overcurrent?
If your Lenze Inverter indicates a continuous overcurrent, take these steps: * Inspect the motor and wiring for any short circuits. * Examine the brake resistor and its wiring. * Verify the motor circuit configuration (delta or star connection). * Confirm that the motor data settings are correct.
What causes Lenze Inverter motor overtemperature and how to resolve it?
If the motor is overheating: * Check the drive sizing. * Inspect the motor temperature sensor and wiring (X109/T1 and X109/T2).
How to troubleshoot a short circuit or earth leakage on the motor side of a Lenze Inverter?
To troubleshoot a short circuit or earth leakage on the motor side: * Check the motor cable. * Consider the length of the motor cable. * Use a shorter or lower-capacitance motor cable.
How do I resolve an overtemperature fault on my Lenze I55BE F Inverter?
To resolve an overtemperature fault: 1. Check the mains voltage. 2. Ensure sufficient cooling for the device (check the heatsink temperature in P117.01). 3. Clean the fan and ventilation slots; replace the fan if necessary. 4. Reduce the switching frequency (P305.00).
What to do if Lenze I55BE F Inverter shows 'i²*t overload (thermal state)'?
If the Lenze Inverter displays an 'i²*t overload (thermal state)' message, take the following actions: * Check the drive sizing. * Inspect the machine/driven mechanics for excessive load. * Verify the motor data settings. * Reduce the values for slip compensation (P315.01, P315.02) and oscillation damping (P318.01, P318.02).
How to troubleshoot a mains phase fault on Lenze Inverter?
To address a mains phase fault, check the wiring of the mains connection and inspect the fuses.
What should I do if my Lenze I55BE F Inverter displays 'DC-bus voltage too low for switch-on'?
If the Lenze Inverter displays a message indicating that the DC-bus voltage is too low for switch-on, you should: * Check the mains voltage. * Check the fuses. * Check the mains settings.
What should I do if the heatsink fan on my Lenze I55BE F Inverter is having issues?
If there are issues with the heatsink fan: * Clean the fan and ventilation slots. * If required, replace the fan. Note that the fans can be unlocked via locking hooks before removal.
What causes a 24 V supply fault on a Lenze Inverter?
If there's a 24 V supply fault: * Check the optional external 24V voltage supply (terminal X3/24E), if connected. * Check the mains voltage.
