12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
[Pr.25] Acceleration time 1 to [Pr.27] Acceleration time 3
These parameters set the time for the speed to increase from zero to the "[Pr.8] Speed limit value" ("[Pr.31] JOG speed limit
value" at JOG operation control) during a positioning operation.
[Pr.28] Deceleration time 1 to [Pr.30] Deceleration time 3
These parameters set the time for the speed to decrease from the "[Pr.8] Speed limit value" ("[Pr.31] JOG speed limit value" at
JOG operation control) to zero during a positioning operation.
[Pr.31] JOG speed limit value
Set the maximum speed for JOG operation.
*1 The range of JOG speed limit value when "[Pr.83] Speed control 10  multiplier setting for degree axis" is valid: 0.01 to
20000000.00 (degree/min)
*2 The range of JOG speed limit value when "[Pr.83] Speed control 10  multiplier setting for degree axis" is valid: 1 to 2000000000 ( 10
-
2
degree/min)
Set the "JOG speed limit value" to a value less than "[Pr.8] Speed limit value". If the "speed limit value" is
exceeded, the error "JOG speed limit value error" (error code: 1AB7H) will occur.
