MHT258a (Engl.)11-15
(2) MICREX-SX
FB (function block) for acquiring a current position output (see 5.4.5).
RD_REQ : Request current position read [BOOL]
RD_ANS : Answer current position read [BOOL]
ANS_BIT1 : Amplifier data bit 1 [BOOL]
ANS_BIT2 : Amplifier data bit 2 [BOOL]
RD_COM : Read command to amplifier [BOOL]
RD_RUN : Reading [BOOL]
RD_OK : Normal end of read [BOOL]
RD_NG : Abnormal end of read [BOOL]
ABS_POS : Current position data [DINT]
Turning on “RD_REQ” executes a sequence of current position acquisition.
The current position is outputted in [DINT] form to “ABS_POS” terminal.
Connect each terminal to the amplifier.
RD_COM : Current position output command (control assign No. 56)
RD_ANS : OUT2
ANS_BIT1 : OUT3 of amplifier terminals
ANS_BIT2 : OUT4
