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 controller’s 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 controller’s 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.
