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 to do if my Lenze i550 Inverter displays a heatsink fan warning?
If your Lenze Inverter displays a heatsink fan warning, you should: * Clean fan and ventilation slots. If required, replace fan. The fans can be unlocked via locking hooks and can then be removed.
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.
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 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 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 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 to do if my Lenze Inverter experiences motor overspeed?
If your Lenze Inverter experiences motor overspeed, adapt the maximum motor speed (P322.00) and the error threshold (P350.01).
What to do if my Lenze i550 Inverter displays 'Automatic start disabled'?
If your Lenze Inverter displays 'Automatic start disabled', deactivate the start command and reset the error.
What does 'Keypad full control active' mean on my Lenze i550 Inverter and how do I exit?
If your Lenze Inverter indicates that 'Keypad full control' is active, press the keypad key to exit the control mode.
