Contact Input Speed Control Operation
Contact input speed control performs the following operation.
The following input signals are used to start and stop the motor.
→ Input IN1 CN1-1
Speed Selection 1 For Speed/Torque
Control
→ Input IN2 CN1-2
Speed Selection 2 For Speed/Torque

Preset values (0 or 1) and input signal status in the portions indicated by horizontal
bars (−) are optional.
Set the rotation directions for Cn-1F, Cn-20, and Cn-21 in bits 3, 4, and 5 of Cn-02
respectively.
Note For the speed/torque control type, control by external reference (voltage refer-
ence) is possible when the contact input speed control function is used by setting
bits A and B of parameter Cn-01.
