What causes motor overload in Lenze Inverter?
If the Lenze Inverter displays a motor overload (I2t overload) because the motor is thermally overloaded due to impermissible continuous current or frequent/long acceleration processes, check the controller selection and the setting of c20.
What causes single phase fault in Lenze SMD Inverter?
If the Lenze Inverter experiences a single phase fault because a mains phase has been lost, check the mains voltage.
How to deactivate DC-injection brake on Lenze SMD Inverter?
If the Lenze Inverter's DC-injection brake is active because it was activated via digital input or automatically, deactivate the DC-injection brake by setting the digital input to LOW or wait for it to deactivate automatically after the holding time c06 has expired.
What to do if Lenze SMD shows short circuit due to defective motor cable?
If the Lenze Inverter experiences a short-circuit or overload due to a defective motor cable, check the wiring.
What if Lenze SMD Inverter shows short circuit due to internal fault in motor?
If the Lenze Inverter experiences a short-circuit or overload due to an internal fault in the motor, check the motor.
What if Lenze Inverter shows short circuit due to frequent and long overload?
If the Lenze Inverter experiences a short-circuit or overload due to frequent and long overload, check the controller selection.
What to do if Lenze SMD Inverter controller is overtemperature?
If the Lenze Inverter controller is overtemperature because it is too hot inside, reduce the controller load and improve cooling.
How to resolve overvoltage on DC bus due to short deceleration time on Lenze SMD Inverter?
If the Lenze Inverter experiences an overvoltage on the DC bus due to an excessively short deceleration time or the motor being in generator mode, increase the deceleration time or use the dynamic braking option.
What to do if overvoltage is caused by earth leakage in Lenze SMD Inverter?
If the Lenze Inverter experiences overvoltage on the DC bus due to earth leakage on the motor side, check the motor/motor cable, separating the motor from the controller.
