For Speed Control only
Use these parameters to set motor speeds
when the contact input speed control function
is used.
If a value higher than the maximum speed is
set, the maximum speed value is used.
Speed selection input signals /P-CL (1CN-45)
and /N-CL (1CN-46), and rotation direction
selection signal /P-CON (1CN-41) enable the
motor to run at the preset speeds.
3. Set the soft start time.
