How to fix motor overload (I2 x t overload) on Lenze Starttec E71MM402 Controller?
If the Lenze Controller shows a motor overload (I2 x t overload), especially if C0123 = -1-, this can be due to frequent or excessive acceleration processes. To resolve this, check the setting of C0120.
What to do if Lenze Controller shows a short circuit error?
If the Lenze Controller indicates a short circuit, the cause may be a short circuit or overcurrent (8 Ir). To resolve this, find the reason for the short circuit and inspect the motor cable. Also, check the brake.
Why is my Lenze Starttec E71MM402 Controller showing a mains failure?
A mains failure in your Lenze Controller can occur due to no mains voltage or blown fuses. Verify the mains voltage and check the fuses.
What causes an error in mains phase on Lenze Starttec E71MM402 Controller?
An error in the mains phase of your Lenze Controller, when C0122 = -0-, can be caused by a mixed-up mains phase connection to the terminals (wrong direction of rotation) or the failure of one or several mains phases. Correct the phase connection and check the mains cables.
What to do if Lenze Controller shows PTC monitoring TRIP error?
If your Lenze Controller displays a PTC monitoring (TRIP) error, especially if CC00111199 = 11, it may be because the motor is too hot due to impermissibly high currents or frequent, excessively long acceleration processes, or because no PTC is connected. Check the drive selection, connect the PTC, or switch off monitoring.
Why is the housing temperature of my Lenze Starttec E71MM402 too high?
The housing temperature of your Lenze Controller may be too high due to several reasons: the ambient temperature being above +60 °C, a very dirty heatsink, impermissibly high current and frequent and excessively long acceleration processes, or a defective load/bearings. Let the device cool down and ensure improved ventilation, clean the heatsink, check the drive selection, and inspect the load and replace defective bearings if necessary.
What does PTC monitoring WARN mean on Lenze Starttec E71MM402 Controller?
If your Lenze Controller displays a PTC monitoring (WARN) message when CC00111199 == 22, it indicates that the motor is too hot due to impermissibly high currents or frequent excessively long acceleration processes, or because no PTC is connected. Check the drive selection.
