What does Inv cycl data mean on Lenze DC Drives?
- MMaria BlairSep 22, 2025
If your Lenze DC Drives display 'Inv cycl data', it means PROFINET invalid cyclic data (IO data marked bad).
What does Inv cycl data mean on Lenze DC Drives?
If your Lenze DC Drives display 'Inv cycl data', it means PROFINET invalid cyclic data (IO data marked bad).
What to do if Lenze i550 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 i550 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 i550?
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 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.
How to troubleshoot 24-V supply overload in Lenze Inverter?
To troubleshoot a 24-V supply overload in your Lenze Inverter, check the 24 V output and digital outputs for earth fault or overload.
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 to do if my Lenze i550 Inverter shows DC bus overvoltage?
If your Lenze Inverter shows a DC bus overvoltage error, you should: * Reduce dynamic performance of the load profile. * Check mains voltage. * Check settings for braking energy management. * Connect brake resistor to the power unit and activate the integrated brake chopper. (P706.01 = 0: Brake resistance).
What to do if my Lenze i550 Inverter displays a warning for DC bus overvoltage?
If your Lenze Inverter shows a warning for DC bus overvoltage, you should: * Reduce dynamic performance of the load profile. * Check mains voltage. * Check settings for braking energy management. * Connect brake resistor to the power unit and activate the integrated brake chopper. (P706.01 = 0: Brake resistance).
