Additional Trip Codes and Detailed Explanations

    th - Over Temperature (Motor Thermistor) (Trip Code: 24)
+ Condition: Excessive temperature detected by the motor thermistor.
- Possible Causes:
>> This indicates the motor is overheating, which can be due to inadequate cooling, excessive load, or prolonged operation at high currents. The issue may require checking the motor cooling system, load conditions, or ambient temperature to ensure it is within the motor's specifications.

    O.Ld1 - +24V or Digital Output Overload (Trip Code: 26)
+ Condition: Overload or short circuit detected on the +24V output or digital output.
- Possible Causes:
>> An excessive load or short circuit condition on the +24V supply output, often due to faulty wiring, excessive loads connected to the output, or a short circuit condition. This trip is not resettable via the Enable/Reset terminal; use the Stop/Reset key instead.

    cL - Current Loop Loss on Terminal 5 (Trip Code: 28)
+ Condition: Loss of current loop input on terminal 5.
- Possible Causes:
>> The input current falls below 3mA when operating in 4-20mA or 20-4mA mode, possibly due to a break in the current loop, incorrect wiring, or failure in the current source. Ensuring proper current loop integrity and configuration is critical.

    SCL - User Serial Communications Watchdog Failure (Trip Code: 30)
+ Condition: Serial communications failure between Drive and master controller.
- Possible Causes:
>> Loss of communication, often due to issues like cable disconnection, interference, or incorrect communication settings. This might require checking all serial connections, ensuring proper grounding, and verifying parameter settings for communication.

    EEF - Internal EEPROM Failure (Trip Code: 31)
+ Condition: Failure of internal EEPROM memory.
- Possible Causes:
>> Possible corruption or loss of parameter values due to severe electrical noise or a hardware fault. To address this, set default parameters (refer to parameter 29) and ensure the installation environment is free from electrical noise.

    PH - Phase Loss (Trip Code: 32)
+ Condition: Loss of one of the input phases.
- Possible Causes:
>> One of the three input phases is disconnected, which applies to 200V/400V three-phase units only. This can occur due to a blown fuse, a broken wire, or an issue with the supply voltage. Immediate inspection of the input power supply is recommended.

    rS - Stator Resistance Measurement Failure (Trip Code: 33)
+ Condition: Failure in measuring the stator resistance.
- Possible Causes:
>> Motor cable disconnection during measurement, or the motor is too small for the Drive's capability. Ensure that the motor connections are intact and retry the measurement process. Refer to parameter 38 for further details.

    trxx - User Trips (Trip Code Range: 40-99)
+ Condition: User-defined trips.
- Possible Causes:
>> Custom trips configured by the user, where 'xx' represents the specific user trip number. These trips are typically set up for specific application requirements or safety protocols.

    F.bus - Field Bus Disconnection (Trip Code: 180)
+ Condition: Disconnection of field bus while in use.
- Possible Causes:
>> Indicates a loss of communication between the Drive and the field bus network. Check for network integrity, proper cable connections, and configuration settings.

    C.Err - Quickey Memory Corrupt (Trip Code: 182)
+ Condition: Memory corruption detected in Quickey.
- Possible Causes:
>> This might occur due to a bad connection or actual memory corruption in the Quickey device. Inspect and secure all connections or replace the Quickey if necessary.

    C.dat - Quickey with No Data (Trip Code: 183)
+ Condition: Quickey being read is new or empty.
- Possible Causes:
>> A newly inserted or uninitialized Quickey device, indicating no data is stored. Initialize or configure the Quickey as needed.

    C.Acc - Quickey Write Fail (Trip Code: 185)
+ Condition: Failure to write data to Quickey.
- Possible Causes:
>> A bad connection or a faulty Quickey device. Secure all connections and, if the issue persists, replace the Quickey.

    C.rtg - Quickey Voltage Rating Change (Trip Code: 186)
+ Condition: Quickey with a different voltage rating is read by the Drive.
- Possible Causes:
>> A previously programmed Quickey is incompatible with the current Drive’s voltage rating. Ensure Quickey compatibility before use.

    O.Ld2 - +28V Serial Communications Power Supply Overload (Trip Code: 188)
+ Condition: Overload or short circuit on the +28V serial communications power supply.
- Possible Causes:
>> An overload exceeding 110mA or a short circuit on the +28V power supply for serial communications, potentially caused by excessive devices drawing power or wiring faults.

    O.cL - Current Loop Input Overload (Trip Code: 189)
+ Condition: Excessive input current in the current loop.
- Possible Causes:
>> Input current exceeds 25mA, indicating a fault in the loop configuration or an inappropriate current source. Check all loop parameters and connections.

    Motor Runs Unstable
+ Condition: The motor or motor connections have changed.
- Possible Causes:
>> Changes in motor wiring or replacement of the motor can cause instability. Check all motor connections and perform a Drive re-autotune (see parameter 38) to align with the new motor characteristics.

Note on Resetting and Overvoltage Trip Levels:

    O.Ld1 Trip Reset: This trip cannot be reset using the Enable/Reset terminal; use the Stop/Reset key.
    Reset Delay: Certain trips (like overcurrent trips) have a mandatory 10-second delay before they can be reset.
    Overvoltage Trip Levels:
        200V units trip at 420VDC.
        400V units trip at 830VDC.

Diagnostic Recommendations:

If any of these trips occur frequently or cannot be resolved through basic troubleshooting, it is advisable to consult a Drive Centre for further diagnostics and support. Ensuring proper installation practices, routine maintenance, and parameter optimization can greatly enhance the operational reliability of the Drive and mitigate the recurrence of these trips.
