LAN Feedbacks
Several LAN feedback signals are averaged versions of internal drive signals. The
signals that fall in this category appear in dedicated floating point feedback channels.
The averaging is sequential (not rolling), and the averaging time is specified by
parameter LAN fbk avg time.
The following table specifies the LAN Signal Map feedback signals.
