Follower fault

What does 74 mean?

This fault code is generated when the drive is configured in a Master Follower function and one or more of the connected follower drives experience a fault condition. This drive reports the fault state of another drive in the system. The root cause lies within the specific follower drive that tripped to fault.

• Loss of communication with the master drive in a Master Follower configuration.
• Follower drive not receiving encoder feedback from the master.
• Incorrect configuration of Master Follower parameters (e.g., P2-30, P2-31).
• Encoder signal integrity issues from the master drive.
• Drive operating outside the specified speed or position range for follower mode.

Click steps to track your progress.

1. 1

   Verify communication link between master and follower drives.

2. 2

   Check encoder output signal (e.g., A/B pulses) from the master drive's encoder terminal.

3. 3

   Confirm parameter P2-30 (Master/Follower Mode) is set correctly on the follower drive.

4. 4

   Verify parameter P2-31 (Follower Type) matches the master drive's configuration.

5. 5

   Ensure the master drive is operational and its encoder is functioning correctly.
