What to do if my Lenze i550 shows brake resistor overload?
If your Lenze Inverter displays a brake resistor overload, you should: * Check drive sizing. * Check settings for the braking energy management. Note! The error will be reset if the thermal load falls below the error threshold (P707.09) of - 20 %.
What should I do if my Lenze i550 keypad is removed?
If the keypad is removed from your Lenze Inverter, plug the keypad back in or activate another control source.
What to do if my Lenze i550 indicates 'Trigger/functions connected incorrectly'?
If your Lenze Inverter indicates that triggers or functions are connected incorrectly, you should: * Check and correct the assignment of the triggers to the functions. * With keypad or network control, the two functions “Inverter enable” (P400.01) and “Run” (P400.02) can also be set to “Constant TRUE [1]” to start the motor.
What to do if my Lenze i550 shows a 24-V supply overload?
If your Lenze Inverter is showing a 24-V supply overload, you should check the 24-V output and digital outputs for earth fault or overload.
What to do if my Lenze Inverter shows a 24-V supply fault?
If your Lenze Inverter shows a 24-V supply fault, you should: * Check optional external 24-V voltage supply (terminal X3/24E), if connected. * Check mains voltage.
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.
What to do if my Lenze i550 is overheating?
If your Lenze Inverter is showing an overtemperature fault, you should: * Check mains voltage. * Provide for a sufficient cooling of the device (display of the heatsink temperature in P117.01). * Clean fan and ventilation slots. If required, replace fan. * Reduce switching frequency (P305.00).
What causes motor overcurrent in Lenze i550 Inverter and how can I fix it?
If your Lenze Inverter is experiencing motor overcurrent, you should: * Check motor load. * Check drive sizing. * Adapt the set error threshold (P353.01).
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 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.
