Open
Loop
When fire mode is active, the motor runs with a
fixed speed based on a reference set. The unit is
the same as selected in
.

Closed
Loop
When fire mode is active, the built-in PID
controller controls the speed based on the
setpoint and a feedback signal selected in
parameter 24-07 Fire Mode Feedback Source
. Select
the unit in
parameter 24-02 Fire Mode Unit
. For
other PID controller settings use parameter group
20-** FC Closed Loop
as for normal operation. If the
motor also is controlled by the built-in PID
controller when in normal operation, the same
transmitter can be used for both cases by
selecting the same source.
