Pr2.23 "Position command FIR filter"
Specifies the time required to reach Vc for a square wave command with a target velocity of Vc as shown in the figure
below.
*1 Actual average travel times contains absolute error of 0.2 ms maximum when the set value multiplied by 0.1 ms is less than
10 ms and relative error of 1.6% maximum when the set value multiplied by 0.1 ms is 10 ms or greater.
*2 Before changing Pr2.23 "Position command FIR filter," stop the command pulse, and wait until the time for filter switching
passes. The time for filter switching is as follows: the set value
0.1 ms + 0.25 ms in the range of 10 ms or smaller, and the
set value
0.1 ms
1.05 ms in the range of 10 ms or greater. When changing Pr2.23 "Position command FIR filter" during
inputting a command pulse, the change is not updated immediately. It is updated when no command pulse is present during
the time for filter switching.
*3 There is a delay until the change in Pr2.23 "Position command FIR filter" is applied to internal calculation. If the switching
timing described in *2 comes during the delay, the change may be suspended.
