For the Junma Servo Driver, all input signals are mapped to a fixed location on
the CN1 I/O connector. The table below shows the input signals and pin
numbers.

P_OT (active high)
N_OT (active high)
DEC (active low)
EXT1 (active low)
BRK (active low)
E-STP (active high)
For the G-Series Servo Driver, all input signals are mapped to a fixed location
on the CN1 I/O connector. The table below shows the input signals and pin
numbers.

P_OT (active high)
N_OT (active high)

For more information on the CN1 I/O connector pins on the Servo Drivers,
refer to the Sigma-II Servo Driver manual, the Sigma-V Servo Driver manual,
the Junma series Servo Driver manual and the G-Series series Servo Driver
manual.
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
