Using Contact Input Speed Control
To use the contact input speed control function, perform the following settings.
1) Set the following memory switch to 1.
Cn-02 Bit 2
Contact Input Speed Control
Selection
(1: Enable, 0: Disable)
Factory
Setting: 0
For Speed/Torque Control
The contact input speed control function will be enabled.
If the contact input speed control function is used,
the contents of the input signals shown below will
change.

Use these parameters to set motor speeds when
the contact input speed control function is used
(set bit 2 of memory switch Cn-02).
Speed selection input signals IN1 and IN2 enable
the motor to run at the preset speeds.
