Configuring the Velocity Control
Instructions:
1.) Set output configuration
■
SOR0 [enter]
➔
Sets Source for Command Velocity: RS-232
■
POR 8 [enter]
➔
Proportional Term = 8 (example)
■
I20 [enter]
➔
Integral Term = 20 (example)
■
V1000 [enter]
➔
Sets Velocity to 1/3 of Maximum Appli-
cation Speed (only an example value)
■
AC10000 [enter]
➔
Sets Acceleration to Maximum Appli-
cation Value (only an example value)
2.) Raise the Proportional Term
POR 13 [enter]
➔
Proportional Term = 13
(Step Width 5, smaller later)
3.) Velocity Jump
V2000 [enter]
➔
Velocity jumps from 1/3 to 2/3 the
Maximum Application Speed
(only an example value)
4.) Velocity Jump
V1000 [enter]
➔
Velocity jumps from 2/3 to 1/3 the
Maximum Application Speed
(only an example value)
5.) Repeat steps 2-4 until the controller becomes unstable. Then
reduce the Proportional Term until the stabilty is achieved.
6.) Repeat steps 2-5 with the Integral Term.
Fine Tuning the Digital Filter
The digital filter parameters can be adjusted to improve the
dynamic performance. These parameters should be carefully
chosen to fit the application because they have a great influence
on performance.
