Setting Parameters According to Host Controller

This section describes how to connect a Σ-Series Servo to a host controller and how to
set parameters.

2.2.1 Speed References

Input a speed reference by using the following input signal "speed reference input." Since this
signal can be used in different ways, set the optimum reference input for the system to be
created.
Speed reference input
(analog voltage input)
Torque reference input
(analog voltage input)
→ Input V-REF CN1-12
→ Input SG CN1-13
Speed/Torque
Use these signals when speed control is selected (bits
A and B of memory switch Cn-01).
For ordinary speed control, always wire the V-REF
and SG terminals.
Motor speed is controlled in proportion to the input
voltage between V-REF and SG.
Setting Example
Cn-03 = 500:
Examples:
+6 V input → 3000 min
+1 V input → 500 min
−3 V input → 1500 min
