Function
When the following error exceeds the value entered here, the control
automatically reduces the axis feedrate by 50%. Axis feedrates remain
reduced by 50% until the following error drops below the value entered
here. At that time, the control increases the feedrate to the originally
programmed speed.
Important: The value entered here must be less than or equal to the value
entered for Excess Error, or a Warning: ”SERVO AMP FE LIMITS
CORRECTED”occurs.

Notes
Typically the value entered here is at least 10% less than the value entered
for Excess Error. If desired, the Feedrate Suppression Point can be
disabled by entering a value equal to the value entered for the Excess
Error.
This parameter must be set independently for each axis.
