It is a signal to switch the parameters to indicate the speed or inching (incremental) distance
when in JOG operation and inching operation.
Refer to [Relation between Settings and Operations for JVEL/JISL] below for the relation
between settings and operations.

This signal changes over the jog operation and the inching (incremental) operation.
JISL = OFF : Jog operation
JISL = ON : Inching operation
When the JISL signal is turned ON (for inching operation) during the jog operation, the actuator
is decelerated and performs the inching operation.
When the JISL signal is turned OFF (jog) while the actuator is moving by inching, the actuator
will complete the movement and then switch to the jog function.
Refer to [Relation between Settings and Operations for JVEL/JISL] below for the relation
between settings and operations.
[Relation between Settings and Operations for JVEL/JISL]
The relation of ON and OFF of Jog-speed/inch-distance switching (JVEL) and Jog/inching
switching (JISL) is as shown in the table below.
JISL JISL = OFF (Jog operation) JISL = ON (Inching operation)
Operation When the JOG +/JOG – signal is ON. Upon detection of the leading (ON edge)
of the JOG +/JOG - signal.
