(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.
Japan resistor
RRS10 or equivalent
ST2
DICOM
P15R
VC
LG
SD
Servo amplifier

Note. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.9.3.
(b) Speed command value selection
Select any of the speed settings by the internal speed commands 1 to 3 and by VC (Analog speed
command) using SP1 (Speed selection 1) and SP2 (Speed selection 2) as follows.

To select VC (Analog speed command) and a speed command value of internal speed commands 1
to 7, enable SP3 (Speed selection 3) with [Pr. PD03] to [Pr. PD22].

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.
