Chapter 5 Trial operation and Tuning
The speed command selection is determined by SPD0 and SPD1. See the table below.
Speed DI signal of CN1
Command
SPD1
No.
S1 0
S2 0
S3 1
S4 1
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.
Set parameter P1-10 to 1000.
Set parameter P1-11 to -30000.
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.
(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 it currently executes S4 command
(-3000 r/min). The rotation speed is -3000 r/min.
(6) Steps (3), (4), and (5) can be repeatedly executed.
(7) If users desire to stop the motor, switch OFF DI1 (Servo OFF).
