*1 Range of speed limit value when "[Pr.83] Speed control 10  multiplier setting for degree axis" is set to valid: 0.01 to 20000000.00
(degree/min)
*2 Range of speed limit value when "[Pr.83] Speed control 10  multiplier setting for degree axis" is set to valid: 1 to 2000000000 (  10

[Pr.9] Acceleration time 0, [Pr.10] Deceleration time 0
"[Pr.9] Acceleration time 0" specifies the time for the speed to increase from zero to "[Pr.8] Speed limit value" ("[Pr.31] JOG
speed limit value" at JOG operation control). "[Pr.10] Deceleration time 0" specifies the time for the speed to decrease from
"[Pr.8] Speed limit value" ("[Pr.31] JOG speed limit value" at JOG operation control) to zero.
Speed
[Pr.9] Acceleration time 0
• If the positioning speed is set lower than the parameter-defined speed limit value, the actual acceleration/deceleration time
will be relatively short. Thus, set the maximum positioning speed equal to or only a little lower than the parameter-defined
speed limit value.
• These settings are valid for home position return, positioning and JOG operations.
• When the positioning involves interpolation, the acceleration/deceleration time defined for the reference axis is valid.
