2. Set three motor speeds in the following parameters.
Cn-1F
SPEED1
1st Speed (Contact
Input Speed Control)
Unit:
min −1
Setting
Range: 0 to
10000
Factory
Setting:
100
For Speed Control only
Cn-20
SPEED2
2nd Speed (Contact
Input Speed Control)
Unit:
min −1
Setting
Range: 0 to
10000
Factory
Setting:
200
For Speed Control only
Cn-21
SPEED3
3rd Speed (Contact
Input Speed Control)
Unit:
min −1
Setting
Range: 0 to
10000
Factory
Setting:
300
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.
