The Speed command selection is determined by SPD0 and SPD1. See the table below.

0: means the switch is open (off).
1: means the switch is closed (on).
The parameter setting range of the internal register is from -60000 to +60000. Speed setting =
setting value x 0.1 rpm. For example, P1.009 = +30000, speed setting = +30000 X 0.1 rpm =
+3000 rpm.
Command setting for the speed register:
Set P1.009 to +30000.
Set P1.010 to +1000.
Set P1.011 to -30000.
Motor’s running direction:
Input command Rotation direction
+ CCW (forward direction)
-
CW (reverse direction)
Step 3:
1.
Switch on DI1 and the drive is in the Servo On state.
2.
When both Speed commands of DI3 (SPD0) and DI4 (SPD1) are off, that means it
executes the S1 command. The motor rotates according to analog voltage command.
3.
When DI3 (SPD0) is on, that means it executes the S2 command. The rotation speed is
3000 rpm.
4.
When DI4 (SPD1) is on, that means it executes the S3 command. The rotation speed is
100 rpm.
5.
When both DI3 (SPD0) and DI4 (SPD1) are on, that means it executes the S4 command.
The rotation speed is -3000 rpm.
6.
You can repeatedly execute steps 3, 4, and 5.
7.
If you want to stop the motor, switch off DI1 (Servo Off).
