Klockner Moeller fault codes 2
Hello,
If your Klockner Moeller driver is not actuating the motor;
The Motor Will Not Start
The
motor is not starting, and there is no voltage at outputs U, V, and W.
You can resolve the problem by following the control steps mentioned
below.
Control and Solution Suggestions
+ Is voltage applied to terminals L, N, and/or L1, L2, and L3? If yes, is the ON lamp lit?
Check terminals L1, L2, L3, and U, V, W.
Switch on the supply voltage.
+ Is the LED display on the keypad indicating a fault message (E ……)?
Analyze the cause of the fault message (Section “Messages”, USER MANUAL).
Acknowledge the fault message with the reset command (e.g., by pressing the STOP key).
+ Has a start signal been issued?
Issue the start signal with the START key or through the FWD/REV input.
+ Has a setpoint frequency been entered under PNU F01?
Enter a setpoint frequency under PNU F01.
+ Are the setpoint definitions correctly wired to terminals H, O, and L?
Check that the potentiometer is connected correctly.
+ Are inputs O and OI connected correctly for external setpoint input?
Check that the setpoint signal is correctly connected.
+ Are the digital inputs configured as RST or FRS still active?
Deactivate RST and/or FRS.
Check the signal on digital input 5 (default setting: RST).
+ Has the correct source for the setpoint frequency (PNU A01) been set? Has the correct source for the start signal (PNU A02) been set?
Correct PNU A01 accordingly.
Correct PNU A02 accordingly.
The Motor Turns in the Wrong Direction
+ Are output terminals U, V, and W correctly connected?
Connect the output terminals correctly to the motor according to the desired direction of rotation.
+ Are the control signal terminals correctly wired?
Use the control signal terminal FWD for clockwise operation and REV for anticlockwise operation.
+ Has PNU F04 been correctly configured?
Set the desired direction of rotation under PNU F04.
Other Control and Solution Suggestions
+ Is the motor load too high?
Reduce the motor load.
+ Is a fixed frequency accessed?
Fixed frequencies always have priority over inputs O and OI.
+ Is no setpoint value applied to terminal O or OI?
Check the potentiometer or the external setpoint generator and replace if necessary.
E15: Main Voltage Overly High
- If the supply voltage is higher than permitted, the output voltage is shut down 100 seconds after voltage supply is turned on.
This error code indicates that the supply voltage is excessively high, and as a safety precaution, the output voltage is automatically turned off. This shut-down process occurs approximately 100 seconds after the voltage supply is turned on. Over-voltage could damage electrical components and adversely affect system performance, requiring professional review and intervention in such cases.
E16: Intermittent Mains Failure
Triggered when an intermittent mains failure occurs for at least 15 ms.
A main current fault has occurred lasting at least 15 ms. This message appears when the duration of the main current fault is longer than the time entered under PNU b002 (user manual page 134).
This error code indicates a short interruption in the main power supply. If this interruption lasts longer than the time period specified in the system parameters (PNU b002), this error code is displayed. Interruptions lasting 15 ms or more can cause problems during sensitive operations or critical operations. Hence, when this error code is displayed, it is important to assess the situation and intervene if necessary.
E21: Overtemperature
Indicates that the internal temperature sensor has detected temperatures above the limit, causing the output voltage to be switched off.
If the temperature sensor mounted on the power section records an operating temperature above the allowed limit, the output voltage is turned off.
This error code indicates that the temperature sensor located in the power section of the Drive (Speed control device) has exceeded the permissible temperature limit. In such cases, the output voltage is automatically turned off. Excessive temperature can damage electronic components and compromise the overall safety of the system. Therefore, it is important to identify the source of the problem and call for professional service when this error code appears.
E23: Gate Array Fault
Indicates an internal communication error between the CPU and the gate array.
This error code signifies a communication error between the central processing unit (CPU) and the gate array of the Drive (Speed control device). The gate array is a hardware component consisting of numerous logic gates controlled by the CPU. If a communication error occurs between these two components, it is typically a serious problem, requiring investigation and repair by professional service.
E24: Mains Phase Failure
Indicates that one of the three mains phases has failed.
This error code denotes a fault in one of the three main phases. Most industrial systems and motor drives operate on three-phase power sources. If one of these phases fails, the system might operate imbalanced or not operate at all. Such a fault should be examined and promptly repaired by professional service.
E30: IGBT Fault
Triggered when an excessive current is applied to an IGBT, causing the output voltage to shut off.
If excessive current is applied to an IGBT (transistor) in the power output stage, the output voltage is turned off to protect the transistor.
This error code indicates that excessive current has been applied to an Insulated Gate Bipolar Transistor (IGBT) in the power output stage. IGBTs are used to control high power levels in devices like Variable Frequency Drives (VFD). If excessive current is applied to these components, the system automatically turns off the output voltage. Such a fault usually poses risks to other components of the system and should be examined and repaired by professional service.
E35: Thermistor Fault Signal
If the resistance of an externally connected PTC thermistor is too high, the output voltage is turned off.
This error code signifies that the resistance of an externally connected Positive Temperature Coefficient (PTC) thermistor is above the allowed limit. If the resistance of this thermistor is too high, it typically indicates excessive temperature or a similar issue. In this case, the VFD automatically turns off the output voltage. Such a fault should be investigated by professional service to prevent further damage and to identify the source of the problem.
Low Voltage - The frequency inverter tries to restart due to very low input voltage. If the restart fails, a low-voltage fault is recorded by triggering an error message, and the frequency inverter turns off.
In this scenario, the frequency inverter detects extremely low input voltage and attempts an automatic restart. If this restarting process fails, an error message is generated to record the low-voltage fault, and the device turns off. Low input voltage can pose a serious problem, potentially damaging the inverter or connected systems. Hence, immediate assessment and, if necessary, professional service call are essential when this error message appears.
E60 to E69, E70 to E79: Expansion Module Faults
These indicate faults in the expansion modules 1 or 2, and their connections.
A fault has occurred in Expansion Modules 1 or 2 and their connections. For more information, refer to the manuals of the affected expansion module.
These error codes indicate problems with the connected expansion modules. Expansion modules are additional hardware used to enhance the functionality of a Drive (Speed control device). If there are faults in these modules or their connections, the system may not operate correctly. For detailed diagnosis and solutions, refer to the user manual or technical documentation of the affected expansion module. Such a fault should be examined and repaired by professional service.
