What does external error mean on Lenze Inverter?
If the Lenze Inverter displays 'External error', it means the digital input “TRIP set” is active. To resolve this, remove the external error.
Why Lenze DC Drives show earth fault?
An earth fault in Lenze DC Drives can occur if a motor phase is grounded, so you should check the motor and motor cable. It can also be due to excessive capacitive charging current of the motor cable, in this case use shorter motor cables with lower charging current.
What to do if Lenze DC Drives have controller overtemperature?
If the controller has an overtemperature, it means the controller is too hot inside. To resolve this, reduce the controller load and improve cooling.
What causes automatic start to be inhibited in Lenze DC Drives?
If automatic start is inhibited in Lenze DC Drives, it is because c42 = 0. You should apply a LOW-HIGH signal change at terminal 28.
How to troubleshoot Remote keypad fault on Lenze ESMD302L4TXA?
If the Lenze Inverter shows 'Remote keypad fault', it means the remote keypad is disconnected. To resolve this, check the remote keypad connections.
What to do if Lenze DC Drives show data on EPM not valid?
If Lenze DC Drives indicate that the data on the EPM is not valid, it means the data is not valid for the controller. Use an EPM providing valid data or load the Lenze setting.
What to do for Controller overtemperature on Lenze ESMD302L4TXA Inverter?
If the Lenze Inverter displays 'Controller overtemperature', it means the controller is too hot inside. To resolve this, reduce the controller load and improve cooling.
What does current limit reached mean on Lenze ESMD302L4TXA?
If the Lenze Inverter shows 'Current limit reached', it indicates a controllable overload. This is managed automatically, as described in C22.
What to do if Lenze DC Drives show EPM error?
If Lenze DC Drives display an EPM error, the EPM might be missing or defective. Power down the system and replace the EPM.
What causes motor overload on Lenze ESMD302L4TXA?
If the Lenze Inverter displays a motor overload (I2t overload), it means the motor is thermally overloaded. This can be due to: * Impermissible continuous current. * Frequent or excessively long acceleration processes. To resolve this: * Check the controller selection. * Check the setting of c20.
