CE03 Modbus: Illegal Data Value fault in delta drive

CE03 Modbus: Illegal Data Value fault in delta drive troubleshooting

Description

CE03 means the Address was correct, but the Data Value you tried to write to it is out of range or invalid for that specific parameter.

Causes

1. Out of Range: Trying to write "650Hz" to the Frequency Command when Max Frequency is set to "60Hz".
2. Running Write: Trying to change a parameter (like Motor Poles) that can only be changed when the drive is Stopped.
3. Bit Error: Writing a value of "3" to a parameter that only accepts "0" or "1".

Solution

Validate data:
1. Stop Drive: If writing configuration parameters, stop the motor first.
2. Check Limits: Read the Max/Min limits of the target parameter.
3. Scaling: Remember decimal points. To write "60.00Hz", you usually need to send "6000" (Hex 1770), not "60". Sending "60" might be interpreted as 0.60Hz, or if sending "600000", it triggers CE03.
