allowed Effect:
NC program execution is inhibited.
A190 The NC block which was read in contains the
"inprocess measurement" or "set actual value
Digital input not on-the-fly" function, although a digital input
programmed has not been programmed for this function
(machine data 45).
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
A191 Although the "external block change" function
was programmed, the digital input was not
Digital input not actuated in order to trigger the external block
actuated change.
Effect:
The NC program is interrupted, the axis is
brought to a standstill via the deceleration
ramp.

- The programmed position is less than the
negative software limit switch.
- "Reference point - coordinate" (machine data

switch.
- Incorrect encoder actual value
Effect:
The axis movement is stopped via the
deceleration ramp.

- Incorrect encoder actual value
Effect:

Counter-measure
For the block search function, it is only allowed
to specify a remaining loop count between 0
and the programmed loop count-1.
Program the digital input for the desired
function.
- Correct the program.
- Check the actuation of the digital input.
- Check the machine data and the NC
program.
- Check the encoder actual value.
- Check the machine data and the NC
programs.
- Check the encoder actual value.
The axis number and the positional value must
be specified in every NC block for the roll feed
version.
