Main-
the alternation mode is enabled and VFD
will alternate auxiliary motors on the VFD output
by run time timer.
APP-67-
the alternation run time timer setting is in
hours. The VFD counts only run time and when it
exceeds
APP-67
and VFD output frequency is
lower than
APP-68
setting, VFD stops the motor,
deactivates its relay, then closes next motor relay
and starts again.

enables
external (2

control if it is set to Yes. External PID can be used
to process system value (pressure, temperature etc)
and provide output to VFD speed reference, analog
0-10VDC output or set-point of the main PID
control.
