Position Controller Gain Setting Switch(SW2)
16.6 In-Position Value Setting Switch(SW4)
The Position Controller Gain Switch allows for the correction of the
motor position deviation after stopping caused by load and friction.
Depending on the motor load, the user may have to select a
different gain position to stabilize and to correct positional error
quickly.
To tune the controller
1. Set the switch to“0”position.
2. Start to rotate the switch until system becomes stable.
3.
Rotate the switch 1~2 position to reach better performance.
To select the output condition of In-Position signal, In-Position
output signal is generated when the pulse number of positional
error is lower than selected In-Position value set by this switch
after positioning command is executed.
