3.2.7 Using Torque Controlcont.
92
User constant Cn-03 can be used to change the voltage input range. (This is also applica-
ble to speed restriction.)
Example of Input Circuit:
See the figure on the right.
• For noise control, always use twisted-
pair cables.
• Example of Variable Resistor for Speed Setting:
Type 25HP-10B manufactured by Sakae Tsushin Kogyo Co., Ltd.
When input signal P-CON
is used to switch between speed reference and torque refer-
ence for torque control II, set both bits A and B of memory switch Cn-01 to 1.
→ Input P-CON 1CN-15
Proportional Control, etc. For Speed/Torque
Control and
Position Control
The function of this input signal varies according
to the memory switch setting.

• Torque/Speed Changeover Control
This function is used to switch between torque control and speed control in torque con-
trol II mode.
