Type Axis parameter
Syntax FS_LIMIT
FSLIMIT
Description The FS_LIMIT axis parameter contains the absolute position of the for-
ward software limit in user units.
A software limit for forward movement can be set from the program to
control the working range of the machine. When the limit is reached, the
CJ1W-MCH72 will ramp down the speed of an axis to 0, and then can-
cel the move. Bit 9 of the
AXISSTATUS axis parameter will be turned on
while the axis position is greater than FS_LIMIT .
FS_LIMIT is disabled when it has a value greater than REP_DIST .
Arguments N/A
Example No example.

Type Axis parameter
Syntax FWD_IN
Description The FWD_IN axis parameter contains the input number to be used as a
forward limit input. The valid input range is 0 to 31. Values 0 to 15 repre-
sent physically present inputs of CJ1W-MCH72 I/O connector and are
common for all axes.
Values 16 to 31 are mapped directly to driver inputs that are present on
the CN1 connector. They are unique for each axis. It depends on the
type of Servo Driver which Servo Driver inputs are mapped into inputs
16 to 31. For more information on Servo Driver I/O mapping into the
Trajexia I/O space, refer to section 5-1-4.
For more information on setting driver parameter Pn81E, see Servo
Driver manual. As default the parameter is set to -1, no inputs selected.
If an input number is set and the limit is reached, any forward motion on
that axis will be stopped. Bit 4 of the
AXISSTATUS will also be set.
Note: This input is active low.
Arguments N/A
Example No example.

Type Axis parameter
Syntax FWD_JOG
Description The FWD_JOG axis parameter contains the input number to be used as
a jog forward input. The input can be set from 0 to 31. As default the
parameter is set to -1, no input is selected.
Note: This input is active low.
