3.2 Setting Parameters According to Host Controller
91
Examples: +3 V input → Rated torque in forward direction
+9 V input → 300% of rated torque in forward direction
−0.3 V input → 10% of rated torque in reverse direction
Parameter Cn-13 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.
• Example of Variable Resistor for Speed Setting:
Type 25HP-10B manufactured by Sakae Tsushin Kogyo Co., Ltd.
→ Input V-REF 1CN-5 Speed Reference Input (or
Speed Limit Input)
For Speed/Torque
Control Only
→ Input SG 1CN-6 Signal Ground for Speed
Reference Input
For Speed/Torque
Control Only
These signals are used when speed control is se-
lected.
For normal speed control, always connect these
signal terminals.
Motor speed is controlled so that it is proportional
to the input voltage between V-REF and SG.
Standard Example
Cn-03 = 500: This setting means that 6 V is equivalent to 3000 min
−1 .
Examples: +6 V input → 3000 min −1 in forward direction
+1 V input → 500 min −1 in forward direction
−3 V input → 1500 min −1 in reverse direction
Parameter Cn-03 can be used to change the voltage input range. (This is also applicable
to speed restriction.)
