3. SIGNALS AND WIRING
(b) Speed selection 1 (SP1), speed selection 2 (SP2) and speed command value
Choose any of the speed settings made by the internal speed commands 1 to 3 using speed selection
1 (SP1) and speed selection 2 (SP2) or the speed setting made by the analog speed command (VC).
(Note) External input signals
SP2 SP1
Speed command value
0 0 Analog speed command (VC)
0 1 Internal speed command 1 (parameter No. 8)
1 0 Internal speed command 2 (parameter No. 9)
1 1 Internal speed command 3 (parameter No. 10)
Note. 0: off

The speed may be changed during rotation. In this case, the values set in parameters No. 11 and
12 are used for acceleration/deceleration.
When the speed has been specified under any internal speed command, it does not vary due to the
ambient temperature.
(2) Speed reached (SA)
SA turns on when the servo motor speed has nearly reached the speed set to the internal speed
command or analog speed command.
