MR-J2S-_A_
No. Name and function
8 Internal speed command 1
This is used to set speed 1 of internal speed commands.
Internal speed limit 1
This is used to set speed 1 of internal speed limits.
9 Internal speed command 2
This is used to set speed 2 of internal speed commands.
Internal speed limit 2
This is used to set speed 2 of internal speed limits.
10 Internal speed command 3
This is used to set speed 3 of internal speed commands.
Internal speed limit 3
This is used to set speed 3 of internal speed limits.
11 Speed acceleration time constant
Used to set the acceleration time required to reach the
rated speed from 0 r/min in response to an analog speed
command and internal speed commands 1 to 7.

Setting value of
parameter No.11
For example, for a servo motor with a rated speed of
3000 r/min, set 3000 (3 s) to increase the speed from 0
to 1000 r/min in 1 s.
12 Speed deceleration time constant
Used to set the deceleration time required to reach 0
r/min from the rated speed in response to an analog
speed command and internal speed commands 1 to 7.

If the preset speed
command is lower than the
rated speed,
acceleration/deceleration
time will be shorter.
