182 Control Setting Blocks
Setting the Maximum Deceleration
You can use the Motion Settings block to set the 100% deceleration value
for all subsequent Move or Jog Axis blocks, for the selected physical or
imaginary axis. This does not change the power-up maximum
deceleration value for the axis set in the motion controllers servo setup
menu, but changes only the current working value.
Change Gain
The Change Gain block directly changes the working values of any
physical servo axis’:
Proportional gain
Integral gain
Velocity gain
Feedforward gain
Deadband compensation
The Change Gain block resides on the Advanced Motion Palette.
You can use the Change Gain block to change the working servo gains at
any time. This does not effect the power-up values, entered using the
motion controller’s servo setup menu and stored in non-volatile
application memory.
Gain Values
The measurement unit for each type of gain depends upon the motion
controller you are using. Refer to you motion controllers documentation
to confirm the measurement unit for each type of gain.
!
ATTENTION:
Changing gains can cause an axis to
become unstable. Refer to the Online Help for Gains for more
information.
