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.
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 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 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 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 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 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 causes i²*t overload (thermal state) in Lenze Inverter and how to fix it?
If your Lenze Inverter is showing an i²*t overload (thermal state) error, you should: * Check drive sizing. * Check machine/driven mechanics for excessive load. * Check setting of the motor data. * Reduce values for slip compensation (P315.01, P315.02) and oscillation damping (P318.01, P318.02).
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).
