How to troubleshoot Remote keypad fault on Lenze Inverter?
If the Lenze Inverter shows 'Remote keypad fault', it means the remote keypad is disconnected. To resolve this, check the remote keypad connections.
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 to do if Lenze DC Drives show undervoltage on DC bus?
If Lenze DC Drives show undervoltage on the DC bus, it could be because the mains voltage is too low. Check the mains voltage.
What does DC-injection brake active mean on Lenze ESMD113L4TXA Inverter?
If the Lenze Inverter is showing 'DC-injection brake active', it means the DC-injection brake has been activated either via digital input or automatically. To deactivate it, ensure the digital input is LOW or wait for the holding time c06 to expire if it was activated automatically.
What causes overvoltage on DC bus in Lenze DC Drives and how to fix it?
Overvoltage on the DC bus in Lenze DC Drives can be caused by several factors. It may be due to mains voltage being too high, so you should check the mains voltage. Another cause can be an excessively short deceleration time or the motor operating in generator mode; in this case, increase the deceleration time or use a dynamic braking option. Finally, earth leakage on the motor side can also cause this issue, so check the motor and motor cable, separating the motor from the controller.
What to do for Controller overtemperature on Lenze ESMD113L4TXA 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 Inverter?
If the Lenze Inverter shows 'Current limit reached', it indicates a controllable overload. This is managed automatically, as described in C22.
How to fix communication error on Lenze ESMD113L4TXA?
If the Lenze Inverter reports a communication error, it could be due to the serial timer timing out. In this case, check the serial link connections.
What causes motor overload on Lenze ESMD113L4TXA Inverter?
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.
