îš‹ Switching Operation Source to Communication Option Card
The source of frequency reference and RUN command can be switched between a Communication option
card and the sources selected in b1-01 and b1-02. Set one of the parameters H1-01 to H1-05 (digital input S3
to S7 function selection) to 2 or 36 to enable operation source switchover.
If a RUN command is active, the switchover will not be accepted.
îš„Related Parameters
Multi-function Digital Inputs (H1-01 to H1-05)
îš„Setting Precautions
To use the operation source switching function make the following settings:
• Set b1-01 (frequency reference source) to a value different from 3 (option card).
• Set b1-02 (RUN command source) to a value different from 3 (option card).
• Set one of the parameters H1-01 to H1-05 to 2 or 36.
îš‹ Switching Operation Source to MEMOBUS communication
The frequency reference and RUN command source can be switched between the MEMOBUS communica-
tion via RS-422/485 and the inverter settings in b1-01 and b1-02. Therefore set one of the parameters H1-01 to
H1-05 (digital inputs terminals S3 to S7 function selection) to 6B or 6C.
If a RUN command is active the switchover will not be accepted.
