Sign error: Description

Description

Trend monitoring has 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 movement direction of the set and current 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 directions of movement of the nominal and actual variables do not coincide, the sign in the measuring system or in the drive amplifier must be changed. Alternatively, it is possible to specify a sign reversal of the current position in the axis parameters (see P-AXIS-00230)
• If the manipulated variable has the wrong sign, it must be changed either in the drive or in the axis parameters (see P-AXIS-00231).
