(15) Jogging Speed/Inching Distance Switching (JVEL) PLC Output Signal
This signal switches between the parameter for specifying the jogging speed when jogging operation is selected and the
parameter for specifying the inching distance when inching operation is selected.
The relationships are summarized in the table below.
JVEL signal Jogging operation: JISL = “0” (OFF) Inching operation: JISL = “1” (ON)
“0” (OFF) Parameter No. 26 (Jogging speed)
Parameter No. 26 (Jogging speed)
Parameter No. 48 (Inching distance)
“1” (ON)
Parameter No. 47 (Jogging speed 2) Parameter No. 47 (Jogging speed 2)
Parameter No. 49 (Inching distance 2)
(16) Jogging/Inching Switching (JISL) PLC Output Signal
This signal is used to switch jogging operation and inching operation.
JISL = “0” (OFF): Jogging operation
JISL = “1” (ON): Inching operation
If the JISL signal switches to “1” (ON) during jogging operation, the actuator will decelerate to a stop and the inching
function will become effective. If the JISL signal switches to “0” (OFF) during inching operation, the actuator will
complete the inching operation and then the jogging function will become effective.
Jogging and inching operation commands are based on a combination of JISL, JVEL and JOG+/JOG- signals. The
relationships of these signals are summarized in the table below.
