Chapter 5 Trial operation and Tuning ASDA-A2
5-8 Revision February, 2017
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).
