Switching Operation Source To Communication Option Card; Switching Operation Source To Memobus Communication - YASKAWA Varispeed E7 Instruction Manual And Parameter Description

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 constants H1-01 to H1-05 (multi-function
contact inputs 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.
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 constants H1-01 to H1-05 to 2 or 36.
•
Setting for one of
H1-01 to H1-05

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 (multi-function digital inputs S3 to S7) to 6B or 6C.
If a RUN command is active the switchover will not be accepted.
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 constants H1-01 to H1-05 to 6B or 6C
