It is a signal to switch the parameters to indicate the speed or inching (incremental) distance
when in JOG operation and inching operation. Table below shows the relations.
JVEL signal Jog operation : JISL=OFF Inch operation : JISL=ON
OFF Parameter No.26, “Jog speed” Parameter No.26, “Jog speed”
Parameter No.48, “Inch distance”

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.
