How to fix Loss of 4-20 mA reference on Lenze ESMD751L4TXA?
If the Lenze Inverter indicates 'Loss of 4-20 mA reference', it means the 4-20 mA signal is below 2 mA (C34 = 4). To resolve this, check the signal and signal wire.
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.
How to resolve dynamic braking fault in Lenze DC Drives?
A dynamic braking fault in Lenze DC Drives typically means that the dynamic braking resistors are overheating. To resolve this, increase the deceleration time.
How to fix No access to code on Lenze Inverter?
If the Lenze Inverter displays 'No access to code', it means that changes can only be made when the controller is in OFF or 1nh. To proceed, set terminal 28 to LOW or inhibit by serial link.
What to do for Controller overtemperature on Lenze ESMD751L4TXA 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 ESMD751L4TXA?
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 ESMD751L4TXA Inverter?
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 ESMD751L4TXA?
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.
