JOG Operation
Overview of the JOG operation
Use the hardware stroke limit function when performing the JOG operation at a position close to the upper or
lower limit. (
 Page 241 Hardware stroke limit function)
When the hardware stroke limit function is not used, the workpiece moves beyond the movement range,
resulting in an accident.
Operation
In the JOG operation, Forward run JOG start signal [Y8, YA, YC, YE] or Reverse run JOG start signal [Y9, YB, YD, YF] is
turned on. While one of these signals is on, pulses are output from RD75 to the drive unit to move the workpiece toward the
specified direction. The following shows an operation example of JOG operation.
No. Operation
(1) When a start signal is turned on, the acceleration starts at the acceleration time specified in [Pr.32] JOG operation acceleration time selection in
the direction specified by the start signal. BUSY signal turns on at this time.
(2) When the accelerating workpiece reaches the speed set in [Cd.17] JOG speed, the workpiece continues moving at that speed. (The workpiece
moves at the constant speed during (2) to (3).)
(3) When the start signal is turned off, the deceleration starts at the deceleration time specified in [Pr.33] JOG operation deceleration time selection
from the speed set in [Cd.17] JOG speed.
(4) When the speed reaches 0, the operation stops. BUSY signal turns off at this time.
