(Note-2)
(Note-1): When the "speed control 10 multiplier setting for degree axis" is set to "valid", the setting range is 0.01 to 21474836.47[degree/min].
However, setting range of 0.001 to 2147483.647[degree/min] is displayed in the parameter block setting screen of programming software.
(Note-2): The setting value is invalid in Real mode.
(1) Parameter blocks allow for easy setting changes by allowing data such as
acceleration/deceleration control to be set once and then reused for multiple
positioning processes.
(2) A maximum of 64 parameter blocks can be created.
(3) Parameter blocks can be set using MT Developer2.
(4) Parameter block parameters available are shown in Table 8.2.
(5) Refer to "Q173DCPU/Q172DCPU Motion controller (SV13/SV22) Programming
Manual (REAL MODE)" for details.

return 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.
• Set the time taken to stop from the
1000

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

speed limit value when a rapid stop is
executed.
• Set the S-curve ratio for S-pattern
processing.
