3.2.1 Inputting Speed Reference
1) 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.

→ Input SG-V 1CN-4

For Speed/Torque
Control Only
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-V terminals.
Motor speed is controlled in proportion to the input
voltage between V-REF and SG-V.
