Trial Operation and Panel Display
The speed command selection is determined by SPD0 and SPD1. See the following table:
Speed
command No.
4
S1
S2
S3
S4
0: means the switch is open (off).
1: means the switch is closed (on).
The parameter setting range is from -60000 to 60000. Setting speed = Setting range x unit (0.1
rpm). For example: P1.009 = +30000; Setting speed = +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.

Step 3:
1. Switch on DI1 to put the drive in the Servo On state.
2. Both speed commands: DI3 (SPD0) and DI4 (SPD1) are off. This means that it executes
the S1 command. The motor rotates according to the analog voltage command.
3. When DI3 (SPD0) is on, that means it executes the S2 command (3000 rpm). The rotation
speed is 3000 rpm.
4. When DI4 (SPD1) is on, that means it executes the S3 command (100 rpm). The rotation
speed is 100 rpm.
5. When both DI3 (SPD0) and DI4 (SPD1) are on, that means it executes the S4 command
(-3000 rpm). 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).
