What to do if my Lenze i550 Inverter shows a continuous overcurrent?
If your Lenze Inverter indicates a continuous overcurrent, take these steps: * Inspect the motor and wiring for any short circuits. * Examine the brake resistor and its wiring. * Verify the motor circuit configuration (delta or star connection). * Confirm that the motor data settings are correct.
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).
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 causes Lenze i550 motor overtemperature and how to resolve it?
If the motor is overheating: * Check the drive sizing. * Inspect the motor temperature sensor and wiring (X109/T1 and X109/T2).
What to do if Lenze i550 shows 'i²*t overload (thermal state)'?
If the Lenze Inverter displays an 'i²*t overload (thermal state)' message, take the following actions: * Check the drive sizing. * Inspect the machine/driven mechanics for excessive load. * Verify the motor data settings. * Reduce the values for slip compensation (P315.01, P315.02) and oscillation damping (P318.01, P318.02).
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.
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 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.
