What does current limit reached mean on Lenze ESMD153L4TXA?
- GgcookSep 6, 2025
If the Lenze Inverter shows 'Current limit reached', it indicates a controllable overload. This is managed automatically, as described in C22.
What does current limit reached mean on Lenze ESMD153L4TXA?
If the Lenze Inverter shows 'Current limit reached', it indicates a controllable overload. This is managed automatically, as described in C22.
What to do for Controller overtemperature on Lenze 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.
Why are Lenze ESMD153L4TXA buttons not working?
If the Lenze Inverter indicates that the remote keypad is active, the buttons on the front of the controller are disabled. This is normal operation when the remote keypad is in use.
Why is Lenze ESMD153L4TXA Inverter output frequency 0 Hz?
If the Lenze Inverter's output frequency is 0 Hz and the outputs U, V, W are inhibited, it could be due to: * Setpoint = 0 Hz (C31 = 0): In this case, you need to perform a setpoint selection. * Quick stop activated through digital input or serial link: Deactivate the Quick stop.
What to do if Lenze DC Drives show a short-circuit or overload?
If the Lenze DC Drives indicate a short-circuit or overload, the cause may be a short-circuit. You should find the reason for the short-circuit and check the motor cable. It can also be caused by excessive capacitive charging current of the motor cable, in this case use shorter motor cables with lower charging current. If the acceleration time is too short, increase the acceleration time and check the controller selection. Also, check wiring if the motor cable is defective and check the motor for internal faults. If there is frequent and long overload, check the controller selection.
How to resolve Lenze ESMD153L4TXA stop with inhibited outputs?
If the Lenze Inverter stops and the outputs U, V, W are inhibited, it is because there is a LOW signal at terminal 28. To solve this, set terminal 28 to HIGH.
What causes undervoltage on DC bus in Lenze ESMD153L4TXA?
If the Lenze Inverter shows 'Undervoltage on DC bus', the mains voltage might be too low. Check the mains voltage to ensure it is within the required range.
How to fix communication error on Lenze ESMD153L4TXA 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 does earth fault mean on Lenze ESMD153L4TXA Inverter?
If the Lenze Inverter indicates an earth fault, it could be due to: * A grounded motor phase: Inspect the motor and motor cable. * Excessive capacitive charging current of the motor cable: Use shorter motor cables with a lower charging current.
What causes motor overload on Lenze 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.
