TR200 detected communication loss to
unit controller known as Control Word
Timeout warning on TR200.
(Note: In case where the TR200 losses
communication with the unit controller, the
UC will not see this diagnositc via the
alarm word. This has been included even
though UC will most likely not see this
alarm.)

2, Bit: 12, Dec: 4096 The AFD Harmonic
Filter temperature has exceeded the
maximum allowed value. This diagnostic is
also non-latching on the AFD itself. The
drive calls alarm 60 because that is tied to
I/O pins 12 and 18, which function as a
safety interlock. Note that on the TR200
drive this diagnostic will populate as [A60]
External Hardware Interlock.
