4 PARAMETERS FOR POSITIONING CONTROL
4.3 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 64 blocks can be set as parameter blocks.
(3) Parameter blocks can be set using MT Developer2.
(4) Parameter block to be set are shown in Table 4.2.

• Set the units for
compensation control.
• It can be also 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/home position
return.
• If the positioning speed or
home position return speed
setting exceeds the speed
limit value, control is executed
at the speed limit value.

the speed limit value from
the positioning start.

• Set the time taken to stop
from the speed limit value.

1 to 65535[ms] 1000 ms
• Set the time taken to stop
from the speed limit value at
rapid stop.
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.
