JOG OPERATION
JOG operation
In JOG operation, while the forward run JOG start signal (YC, YE, and Y10) or the reverse
run JOG start signal (YD, YF, and Y11) is ON, the QD72P3C3 outputs pulses to the drive
unit, and moves the workpiece in the specified direction.
The following describes an example of JOG operation.
Turning ON the JOG start signal (YC to Y11) starts acceleration in the direction specified in the JOG start signal (YC to Y11) and at
1)
the time set in " JOG ACC/DEC time". At this time, the BUSY signal (X8 to XA) turns from OFF to ON.

workpiece moves at constant speed from 2) to 3).)
Turning OFF the JOG start signal (YC to Y11) starts deceleration from the speed set in "
3)
" JOG ACC/DEC time".
