4. PARAMETERS FOR POSITIONING CONTROL
4 − 22
4.4 Parameter Block
(1) The parameter blocks serve to make setting changes easy by allowing data
such as the acceleration/deceleration control to be set for each positioning
processing.
(2) A maximum of 16 blocks can be set as parameter blocks.
(3) Parameter blocks can be set at a peripheral device.
(4) The parameter block settings to be made are shown in Table 4.9.

compensation control.
• Can also be used as the
units for the command speed
and allowable error range for
circular interpolation set in
the servo program.

• Set the maximum speed for
positioning/zeroing.
• If the positioning speed or
zeroing speed setting
exceeds the speed limit
value, control is executed at
the speed limit value.

• Set the time taken to reach
the speed limit value from
the start of motion.

time
1 to 65535ms 1000 ms
• Set the time taken to stop
from the speed limit value.,

• Set the time taken to stop
from the speed limit value
when a rapid stop is
executed.
6 S-curve ratio 0 to 100% 0 %
• Set the S-curve ratio for S-
pattern processing.
• When the S-curve ratio is
0%, trapezoidal
acceleration/deceleration
processing is executed.

the locus of the arc and the
set end point coordinates.

POINTS
(1) Parameter blocks are designated in the zeroing data, JOG operation
data, or servo program.
(2) The various parameter block data can be changed in the servo program.
