Use these user constants 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 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.
c) Set the soft start time (for speed/torque control only).
