7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL

1785 Parameter for determining the allowable acceleration in feedrate clamping
by acceleration
[Data type] Word axis
[Unit of data] 1 ms
[Valid data range] 0 to 32767
This parameter is used to set the time required to reach the maximum
cutting feedrate and determine the allowable acceleration when feedrate
clamping by acceleration is performed.
The allowable acceleration is determined from the maximum cutting
feedrate and the data set in this parameter. Parameter 1432 is used as the
maximum cutting feedrate.
