APPLICATIONS
2.2.1 Speed References cont.
Parameter Cn-03 can be used to change the voltage input range.
The adjacent diagram shows an example of an input
circuit.
For noise control, always use twisted-pair cable.
Recommended Variable Resistor for Speed Setting:
Type 25HP-10B manufactured by Sakae Tsushin Kogyo Co., Ltd.

When position control is performed by a host control-
ler such as a Programmable Controller, connect V-
REF and SG to speed reference output terminals on
the host controller. In this case, adjust Cn-03 accord-
ing to output voltage specifications.
Use the memory switch and input signal /P-CON to specify one of the four modes shown be-
low.
