Position control under vector control
222
PARAMETERS
5.5.4
Position control by the FR-A8AL pulse train
input
Position control by the command from the positioning module of the programmable controller is available using the FR-A8AL.

Zero of the most significant digit is not displayed.

Timing to clear the current position 2 monitor value differs depending on the setting value.

During position control under Vector control, if Pr.419 = "1" while the FR-A8AL is not installed (or is disabled), the protective function (E.OPT) is
activated.

During position control under Vector control, if Pr.419 = "1110" while the FR-A8APS is not installed (or is disabled), a protective function (E.OPT)
is activated.
