For more information on the CN1 I/O connector pins on the Servo Drivers,
refer to the specific Servo Driver manuals.
Servo Driver inputs that are mapped into the CJ1W-MCH72 I/O space like this
are accessed within the program per axis and cannot be accessed in the usual
way with the IN command. The only way you can use these inputs in the
program is to assign them to the axis parameters DATUM_IN, FHOLD_IN,
FWD_IN and REV_IN. The inputs of the axis Servo Driver are used,
depending on the axis of which the parameters are set.
Example: We have a Sigma-II and a Junma driver assigned to controller axes
0 and 3. For the Sigma-II driver, we want to use input signal EXT1 (mapped to
CN1-44 if Pn511.2 is set to 4) to serve as reverse limit input for axis 0. For the
Junma driver, we want to use input signal EXT1 (CN1-2) as reverse limit for
axis 3. We can do this with these commands:
REV_IN AXIS(0) = 22
REV_IN AXIS(3) = 22
Note that even though REV_IN parameters for both axes have the same
value, the real inputs used are not the same. For axis 0 the input on CN1-44 of
the Sigma-II driver (assigned to axis 0) is used, but for axis 3 the input on
CN1-41 of the Junma driver (assigned to axis 3) is used. Therefore we say
that those inputs are accessed per axis, they are not unique for the whole
controller. In general, these two inputs have a different status at the same
time. Also note that neither of these two inputs can be accessed using the
command IN. For example the command IN(22) returns the status of controller
software input 22 (unique for all axes), which has a different status than Servo
