(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.

value
• Set the units for
compensation control.
• It can be also used as the
3 — 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.
pulse
/ • If the positioning speed or
200000
s home position return speed
setting exceeds the speed
limit value, control is executed
at the speed limit value.
• Set the time taken to reach
1000 the speed limit value from
ms
the positioning start.
• Set the time taken to stop
1000 ms
from the speed limit value.
• Set the time taken to stop
1000 ms from the speed limit value at
rapid stop.
• Set the S-curve ratio for S-
pattern processing.
• When the S-curve ratio is
0 %
0[%], trapezoidal
acceleration/deceleration
processing is executed.
