What causes overload inverter during acceleration or short circuit in Lenze EVF8215-EV020?
An overload during acceleration or a short circuit can occur if the acceleration time (C012) is too short. In this case, increase the acceleration time and check the drive selection. A defective motor cable can also cause this, so check the wiring. Finally, an interturn fault in the motor itself could be the issue, so check the motor.
What causes overload controller during deceleration in Lenze DC Drives?
An overload of the controller during deceleration is often due to a deceleration time (C013) that is too short. Increase the deceleration time and check the selection of the brake resistor or connect the brake chopper.
What does I x t overload mean in Lenze EVF8215-EV020 DC Drives?
I x t overload can be caused by frequent and too long acceleration processes with overcurrent. In this case, check drive dimensioning.
What causes overload motor in Lenze EVF8215-EV020?
The motor can be overloaded if it's thermally overloaded, perhaps due to an impermissible continuous current. Check the drive selection. Frequent or overly long acceleration processes can also cause this; check the setting under C120.
What causes PTC monitoring issues in Lenze DC Drives?
PTC monitoring issues can arise if the motor is too hot due to excessive current or frequent and overly long acceleration. Check drive dimensioning. Also, the PTC might not be connected; connect the PTC or switch off monitoring (C0585=3).
What does overtemperature unit mean for Lenze DC Drives?
An overtemperature unit indicates that the inside of the unit is too hot. Reduce the controller load, improve cooling, and check the fan in the controller.
Why is my Lenze DC Drives motor not rotating?
The motor might not be rotating due to several reasons: * The DC-bus voltage could be too low, indicated by a red LED blinking every 0.4 seconds and the message LU being displayed. * The controller might be inhibited, shown by a blinking green LED and the display showing OFF, STOP, or AS_LC. * Other potential causes include a setpoint of 0, active DC braking, an active quick-stop function, a JOG setpoint activated with JOG frequency set to 0, a fault message being displayed, or the mechanical motor brake not being released.
What to do if my Lenze EVF8215-EV020 unit overheats?
If the heat sink temperature is higher than the value set in the controller, it could be due to several factors. The ambient temperature (Tu) might be exceeding +40°C or +50°C. Allow the controller to cool and ensure proper ventilation, and check the ambient temperature in the control cabinet. The heat sink might also be dirty, so cleaning it could help. Finally, an incorrect mounting position could be the cause, so try changing it.
What causes undervoltage in Lenze DC Drives?
Undervoltage can be caused by a DC-bus voltage that is too low. Check the mains voltage and the supply module.
What causes short circuit in Lenze EVF8215-EV020 DC Drives?
A short circuit can be caused by a short circuit itself. Find out the cause of the short circuit and check the cable. Also, excessive capacitive charging current of the motor cable can lead to a short circuit; use a motor cable which is shorter or of lower capacitance.
