What to do if my Lenze i550 shows motor overtemperature?
If your Lenze Inverter indicates motor overtemperature, you should: * Check drive sizing. * Check motor thermal sensor and wiring (X109/T1 and X109/T2).
What to do if my Lenze i550 displays 'Device utilization (Ixt) too high'?
If your Lenze Inverter displays a message indicating that device utilization (Ixt) is too high, you should: * Check drive sizing. * Reduce maximum overload current of the inverter (P324.00). * In case of high mass inertias, reduce maximum overload current of the inverter (P324.00) to 150 %.
What to do if my Lenze i550 warns about high device utilization (Ixt)?
If your Lenze Inverter warns about high device utilization (Ixt), check drive sizing.
What to do if my Lenze i550 Inverter shows DC bus undervoltage?
If your Lenze Inverter shows a DC bus undervoltage error, you should: * Check mains voltage. * Check fuses. * Check DC bus voltage (P105.00). * Check mains settings.
What to do if my Lenze i550 displays a warning for DC bus undervoltage?
If your Lenze Inverter displays a warning for DC bus undervoltage, you should: * Check mains voltage. * Check fuses. * Check DC bus voltage. * Check mains settings.
What to do if my Lenze i550 Inverter shows continuous overcurrent?
If your Lenze Inverter displays a continuous overcurrent error, you should: * Check motor and wiring for short circuit. * Check brake resistor and wiring. * Check motor circuit (delta connection, star connection). * Check setting of the motor data.
What to do if my Lenze Inverter shows 'DC bus voltage too low for switch-on'?
If your Lenze Inverter displays a message indicating that the DC bus voltage is too low for switch-on, you should: * Check mains voltage. * Check fuses. * Check mains settings.
Why does my Lenze i550 Inverter show a mains phase fault and how to fix it?
If your Lenze Inverter is showing a mains phase fault, you should: * Check wiring of the mains connection. * Check fuses.
What causes short circuit or earth leakage on the motor side of my Lenze i550 Inverter and how to resolve it?
If you are experiencing a short circuit or earth leakage on the motor side of your Lenze Inverter, you should: * Check motor cable. * Check the length of the motor cable. * Use shorter or lower-capacitance motor cable.
Why Lenze DC Drives show communic.error?
If your Lenze DC Drives display a communication error, this indicates a PROFINET communication stack initialization error, potentially caused by an incorrect station name or IP address during initialization.
