How to troubleshoot Dynamic braking fault on Lenze Inverter?
If the Lenze Inverter is showing a Dynamic braking fault, it indicates that the dynamic braking resistors are overheating. To resolve this, increase the deceleration time.
How to resolve Lenze ESMD751L4TXA Inverter 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 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 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 does earth fault mean on Lenze 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 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.
Why is my Lenze ESMD751L4TXA showing overvoltage on DC bus?
If your Lenze Inverter is experiencing an overvoltage on the DC bus, it could be due to several reasons: * The mains voltage might be too high: Verify the mains voltage. * The deceleration time might be excessively short, or the motor might be in generator mode: Increase the deceleration time or consider using a dynamic braking option. * Earth leakage on the motor side: Check the motor and motor cable, separating the motor from the controller to diagnose.
What to do if Lenze ESMD751L4TXA Inverter shows short-circuit or overload?
If the Lenze Inverter experiences a short-circuit or overload, there are several potential causes: * A short-circuit itself: Investigate the cause and inspect the motor cable. * Excessive capacitive charging current: Use shorter motor cables. * Acceleration time is too short: Increase the acceleration time and check the controller selection. * Defective motor cable: Check the wiring. * Internal fault in the motor: Check the motor. * Frequent and long overload: Check controller selection.
What to do if Lenze DC Drives have a communication error?
If Lenze DC Drives have a communication error, it may be because the serial timer has timed out. Check the serial link connections.
What to do if Lenze DC Drives have a single phase fault?
If Lenze DC Drives have a single phase fault, it means a mains phase has been lost. Check the mains voltage.
