A188
Rem. loop count bl.
search fwd lev1/2 not
allowed
The remaining loop count transferred with
block search for subprogram level 1 or 2 is
greater than the programmed loop count.
Effect:
NC program execution is inhibited.
For the block search function, it is only allowed
to specify a remaining loop count between 0
and the programmed loop count-1.
A190
Digital input not
programmed
The NC block which was read in contains the
"inprocess measurement" or "set actual value
on-the-fly" function, although a digital input
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.
Program the digital input for the desired
function.
A191
Digital input not
actuated
Although the "external block change" function
was programmed, the digital input was not
actuated in order to trigger the external block
change.
Effect:
The NC program is interrupted, the axis is
brought to a standstill via the deceleration
ramp.
- Correct the program.
- Check the actuation of the digital input.
A195
Negative overtravel
reached
- Negative software limit switch position
approached
- "Software limit switches - negative" (machine
data 12) entered incorrectly
- The programmed position is less than the
negative software limit switch.
- "Reference point - coordinate" (machine data
3) is less than the negative software limit
switch.
- Incorrect encoder actual value
Effect:
The axis movement is stopped via the
deceleration ramp.
- Check the machine data and the NC
program.
- Check the encoder actual value.
A196
Positive overtravel
reached
- Positive software limit switch position
approached
- "Software limit switches - positive" (machine
data 13) entered incorrectly¨
- The programmed position is greater than the
positive software limit switch
- "Reference point - coordinate" (machine data
3) is greater than the positive software limit
switch
- Incorrect encoder actual value
Effect:
The axis movement is stopped via the
deceleration ramp.
- Check the machine data and the NC
programs.
- Check the encoder actual value.
A200
No position has been
programmed in
Automatic mode
No position has been programmed in the NC
block for the roll feed version, although the
axis number of the roll feed is specified.
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
The axis number and the positional value must
be specified in every NC block for the roll feed
version.
