3. SIGNALS AND WIRING
(b) Speed selection 1 (SP1), speed selection 2 (SP2), speed selection 3 (SP3) and speed command value
By making speed selection 1 (SP1), speed selection 2 (SP2) and speed selection 3 (SP3) usable by
setting of parameter No. 43 to 47, you can choose the speed command values of internal speed
commands 1 to 7.
(Note) External input signals

Note.0 : SP1/SP2/SP3-SG off (open)
1 : SP1/SP2/SP3-SG on (short)
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-SG are connected when the servo motor speed nearly reaches the speed set to the internal speed
command.
