3.2.6 Using Contact Input Speed Control
1) The contact input speed control function provides easy-to-use speed control. It allows
the user to initially set three different motor speeds in user constants, select one of the
speeds externally by contact input and run the motor.
This function can be used for both speed/torque control and position control.

User constants
No external speed setting
device or pulse generator is
required.
The motor is operated at the
speed set in the user constant.
