Forward/Backward JOG and Inching ON/OFF
JOG Operation: If ‘Inching Movement’ was set as 0, then ‘JOG/Inching ON’ activates JOG operation
without instructions. ‘JOG Speed Upper Limit’ and ‘JOG Accelerate/Decelerate Time’ set in parameter
are used in JOG operation. JOG operation can be executed even when Original Point is not determined.
Inching Operation: If ‘Inching Movement’ was set as non-zero value, then ‘JOG/Inching ON’ activates
Inching operation. It outputs predefined number of pulses (“Inching Movement”) to the drive unit from
PLC-S when the signal is changed from OFF to ON. “Inching Speed” set in parameter is applied here.
