• Standard Setting:

Cn-03 = 500: This setting means that 6 V is equivalent to rated speed (3,000 r/min)
Examples:
+6 V input → 3,000 r/min in forward direction
+1 V input → 500 r/min in forward direction
−3 V input → 1,500 r/min in reverse direction
User constant Cn-03 can be used to change the voltage input range.

• Example of Input Circuit

(See the figure on the right)
For noise control, always use twisted-pair
cables.
Recommended Variable Resistor for Speed Setting:
Type 25HP-10B manufactured by Sakae Tsushin Kogyo Co., Ltd.
When position control is performed by a host con-
troller such as a programmable controller.
Connect V-REF and SG-V to speed reference
output terminals on the host controller. In this
case, adjust Cn-03 according to output voltage
specifications.
2) Use the memory switch and input signal P-CON to specify one of the four modes shown
below.
Cn-01 Bit A Control Mode Selection
Cn-01 Bit B Control Mode Selection
The Servopack for speed/torque control (SGDA-jjjS) provides four different control
modes.
