Sign error: trend monitoring actuated.

Description

Trend monitoring detected a sign error.

It is used for monitoring the sign of the control and encoder signals and can be activated for each axis via the axis parameters (see P-AXIS-00189).

 

Possible error causes:

  • The positive or negative motion directions of the command and actual values do not match.
  • The manipulated variable has the wrong sign. The axis moves in the wrong direction when the NC commands G0/G1 are used.

 

Possible solutions:

  • If the motion directions of the command and actual variables do not match, change the sign in the measurement system or in the drive amplifier. Alternatively, it is possible to specify a sign reversal of the actual position in the axis parameters (see P-AXIS-00230)
  • If the manipulated variable has the wrong sign, change it either in the drive or in the axis parameters (see P-AXIS-00231).
