Auto/Hand Mode Switching By Digital Input - Omron VARISPEED E7 User Manual

Setting precautions
To use the operation source switching function make the following settings:
Set b1-01 (Frequency reference source) to a value different from 2 (Memobus)
•
Set b1-02 (RUN command source) to a value different from 2 (Memobus)
•
Set one of the parameters H1-01 to H1-05 to 6B or 6C

AUTO/HAND Mode Switching by Digital Input

If the HOA Digital Operator (optional available) is connected the Inverter can be switched to AUTO or
HAND mode with digital inputs.
If b1-13 (HAND/AUTO switching during run selection) is set to 1 this is also possible during run, otherwise
the Inverter has to be stopped to enable the switchover. Depending on the setting of b1-13 the functionality of
b1-12 (HAND frequency reference source selection) changes.

HAND/AUTO Switching Behaviour
Inverter has to be stopped for HAND/AUTO switchover.
If started in HAND mode d1-01 becomes the active frequency reference.
Inverter can be switched over during run.
When switched to HAND mode the last AUTO frequency reference is used in
HAND mode and copied into d1-01.
Inverter has to be stopped for HAND/AUTO switchover.
If started in HAND mode the AUTO frequency reference is used.
Inverter can be switched over during run.
When switched to HAND mode d1-01 becomes the active frequency reference.
