3. SIGNALS AND WIRING
(b) Speed selection 1(SP1)/speed selection 2(SP2)/speed selection 3(SP3) and speed limit values
Choose any of the speed settings made by the internal speed limits 1 to 7 using speed selection
1(SP1), speed selection 2(SP2) and speed selection 3(SP3) or the speed setting made by the speed
limit command (VLA), as indicated below.
(Note) Input signals
Setting of parameter
No. 43 to 48 SP3 SP2 SP1
Speed limit value
0 0 Analog speed limit (VLA)
0 1 Internal speed limit 1 (parameter No. 8)
1 0 Internal speed limit 2 (parameter No. 9)
When speed selection
(SP3) is not used
(initial status)
1 1 Internal speed limit 3 (parameter No. 10)
0 0 0 Analog speed limit (VLA)
0 0 1 Internal speed limit 1 (parameter No. 8)
0 1 0 Internal speed limit 2 (parameter No. 9)
0 1 1 Internal speed limit 3 (parameter No. 10)
1 0 0 Internal speed limit 4 (parameter No. 72)
1 0 1 Internal speed limit 5 (parameter No. 73)
1 1 0 Internal speed limit 6 (parameter No. 74)
When speed selection
(SP3) is made valid
1 1 1 Internal speed limit 7 (parameter No. 75)
Note. 0: off
1: on
When the internal speed limits 1 to 7 are used to command the speed, the speed does not vary with
the ambient temperature.
(c) Limiting speed (VLC)
VLC turns on when the servo motor speed reaches the speed limited using any of the internal
speed limits 1 to 7 or the analog speed limit (VLA).
