7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
266
1624
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
[Unit of data] ms
[Valid data range] 0 to 4000 (For exponential acceleration / deceleration)
0 to 8192 (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.
1625 FL rate of exponential acceleration/deceleration in jog feed for each axis
[Data type] Word axis
Valid data range
y
IS-A, IS-B IS-C
Millimeter machine 1 mm/min 6 – 15000 6 – 12000
Inch machine 0.1 inch/min 6 – 6000 6 – 4800
Rotaion axis 1 deg/min 6 – 15000 6 – 12000
Set the lower limit (FL rate) of exponential acceleration/deceleration in
jog feed for each axis.
1722 Rapid traverse feedrate reduction ratio for overlapping rapid traverse blocks
[Data type] Byte axis
[Unit of data] %
[Valid data range] 0 to 100
This parameter is used when rapid traverse blocks are arranged
successively, or when a rapid traverse block is followed by a block that
does not cause movement. When the feedrate for each axis of a block is
reduced to the ratio set in this parameter, the execution of the next block is
started.
NOTE
The parameter No. 1722 is effective when parameter No.
1601 #4 (RTO) is set to 1.
