No interpolation for axis in tracking mode.

Description

The path axis is moving or is to be moved although the axis is in tracking mode (command position = actual position).

There are different reasons why an axis is in tracking mode:

  1. The user commands axis tracking mode via the High Level Interface by setting the HLI signal of the control unit lr_mc_control.follow_up.command to TRUE. (For detailed information on CNC real-time control signals, see
    [HLI// Control commands of an axis].
  2. The axis reverts automatically to tracking mode (internal tracking mode). Possible reasons for this include:
    • This status indicates that the drive is not ready for operation (not yet initialized).
    • There is no valid process data received from the drive.
    • The drive is in error state.
    • The axis is parked (Profidrive drive).
