The speed command selection is determined by SPD0 and SPD1. See the table below. 
Speed 
Command 
No. 
DI signal of CN1 
Command Source  Content  Range 
SPD1  SPD0 
S1 0 0 External analog 
command 
Voltage deviation 
between V-REF and GND 
-10V ~ +10V 
S2 0 1 
Register 
parameter 
P1-09  -60000 ~ 60000 
S3  1  0  P1-10  -60000 ~ 60000 
S4  1  1  P1-11  -60000 ~ 60000 
0: means DI is OFF; 1: means DI is ON 
Register parameter 
The parameter setting range is from -60000 to 60000. Setting speed = Setting range x unit (0.1 
r/min). 
For example: P1-09 = +30000; Setting speed = +30000 x 0.1 r/min = +3000 r/min 
Command setting of speed register 
Set parameter P1-09 to 30000. 
Input command  Rotation direction 
Set parameter P1-10 to 1000.  +  CW 
Set parameter P1-11 to -30000.  -  CCW 
 
Step 3: 
(1)  Users switch ON DI1 and Servo ON. 
(2)  Both DI3 (SPD0) and DI4 (SPD1), the speed command, are OFF, which means it currently 
executes S1 command. The motor rotates according to analog voltage command. 
(3)  When DI3 (SPD0) is ON, it means it currently executes S2 command (3000 r/min). The 
rotation speed is 3000 r/min for rotary motor and 0.03 m/s for linear motor at the moment.  
(4)  When DI4 (SPD1) is ON, it means it currently executes S3 command (100 r/min). The 
rotation speed is 100 r/min. 
(5)  When both DI3 (SPD0) and DI4 (SPD1) are ON, it means S4 command (-3000 r/min) is 
executed at the moment. The rotation speed is -3000 r/min. 
(6)  Step (3), (4) and (5) can be repeatedly executed. 
(7)  If users desire to stop the motor, switch OFF DI1 (Servo OFF).
