What to do if there is DC bus overvoltage in Lenze I55AE137 Inverter?
If you're experiencing DC bus overvoltage in your Lenze Inverter, take these steps: * Reduce the dynamic performance of the load profile. * Check the mains voltage. * Verify the settings for the brake energy management. * Connect a brake resistor to the power unit and activate the integrated brake chopper by setting P706.01 to 0.
Why does Lenze I55AE137 Inverter show a mains phase fault?
A mains phase fault in your Lenze Inverter can be caused by issues with the power supply. Check the mains connection wiring and inspect the fuses to ensure they are working correctly.
How to troubleshoot overtemperature fault in Lenze I55AE137 Inverter?
To troubleshoot an overtemperature fault in your Lenze Inverter: * Check the mains voltage. * Ensure sufficient cooling by monitoring the heatsink temperature (P117.01). * Clean the fan and ventilation slots or replace the fan if needed. * Reduce the switching frequency (P305.00).
What causes high device utilization on Lenze I55AE137?
High device utilization (Ixt) on your Lenze Inverter can occur due to several reasons. Check the drive dimensions. Reduce the maximum overload current of the inverter (P324.00). If you have high mass inertias, reduce the maximum overload current of the inverter (P324.00) to 150 %.
How to fix short circuit on motor side of Lenze Inverter?
To address a short circuit or earth leakage on the motor side of your Lenze Inverter: * Inspect the motor cable. * Consider the length of the motor cable. * Use a shorter or lower-capacitance motor cable.
What to do if Lenze Inverter shows i²*t overload?
If your Lenze Inverter is showing an i²*t overload (thermal state), consider the following: * Verify the drive dimensions. * Check the machine/driven mechanics for excessive load. * Confirm the correct setting of the motor data. * Reduce values for slip compensation (P315.01, P315.02) and oscillation damping (P318.01, P318.02).
Why is my Lenze I55AE137 motor overheating?
If your Lenze Inverter motor is overheating: * Check the drive dimensions. * Check the motor thermal sensor and wiring (terminals X109/T1 and X109/T2).
How to resolve DC bus undervoltage in Lenze Inverter?
To resolve DC bus undervoltage in your Lenze Inverter: * Check the mains voltage. * Check the fuses. * Check the DC bus voltage (P105.00). * Check the mains settings.
What does '24 V supply critical' mean on Lenze I55AE137 Inverter?
If your Lenze Inverter displays '24 V supply critical': * Check the optional external 24 V voltage supply (terminal X3/24E), if connected. * Check the mains voltage.
