AND DECELERATION CONTROL

Set the time constant used for exponential acceleration/deceleration or
linear acceleration/deceleration after interpolation or bell--shaped
acceleration/deceleration after interpolation in cutting feed for each axis.
Except for special applications, the same time constant must be set for all
axes in this parameter. If the time constants set for the axes differ from
each other, proper straight lines and arcs cannot be obtained.

Set the lower limit (FL rate) of exponential acceleration/deceleration in
cutting feed for each axis. Except for special applications, this parameter
must be set to 0 for all axes. If a value other than 0 is specified, proper
straight lines and arcs cannot be obtained.

Time constant of exponential acceleration/deceleration, bell--shaped acceleration/
deceleration after interpolation or linear acceleration/deceleration
after interpolation, in jog feed for each axis.
[Data type] Word axis
[Unitofdata] ms
[Valid data range] 0 to 4000 (For exponential acceleration / deceleration)
0 to 512 (For linear acceleration / deceleration after interpolation or
bell--shaped acceleration/deceleration after interpolation)
Set the time constant used for exponential acceleration/deceleration,
bell--shaped acceleration/deceleration after interpolation or linear
acceleration/deceleration after interpolation in jog feed for each axis.
The type of acceleration/deceleration is determined depending on the
setting in parameter No. 1610.
