(3) Speed setting in speed control mode
(a) Speed command and speed
The servo motor is run at the speeds set in the parameters or at the speed set in the applied voltage
of VC (Analog speed command). The relation between an applied voltage of VC (Analog speed
command) and servo motor speed, and the rotation direction with turning on ST1/ST2 are the same
as section 3.6.2 (1) (a).
Normally, connect as follows.

Note. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.9.3.
(b) Speed command value selection
To select VC (Analog speed command) and a speed command value of internal speed commands 1
to 7, enable SP1 (Speed selection 1), SP2 (Speed selection 2), and SP3 (Speed selection 3) with
[Pr. PD03] to [Pr. PD20].

You can change the speed during rotation. Acceleration/deceleration is performed with the setting
values of [Pr. PC01] and [Pr. PC02].
When the internal speed commands 1 to 7 are used to command a speed, the speed does not vary
with the ambient temperature.
(c) SA (Speed reached)
As in section 3.6.2 (2)
