Idle RPM Idle The normal idle RPM of the engine. 300 1000 500 RPM C
Maximum RPM Maxim The normal maximum RPM developed by the engine. 1300 6000 2500 RPM C
Idle trim IdlAd Adjusts the idle RPM demand for this engine above or
below the nominal idle. Can be used to match two
engines when other demand matching fails. Does not
adjust the maximum RPM.
-200 200 0 RPM C
Full trim FulAd Adjusts the maximum RPM demand for this engine
above or below the nominal idle. Can be used to match
two engines when other demand matching fails. Does
not adjust the idle RPM.

Voltage feedback
scale
VScal The number of millivolts per 1000 RPM for
voltage feedback. For example, a value of 4000
corresponds to 4 volts per 1000 RPM. A voltage
feedback of 6V would correspond to 1500 RPM.
500 6000 4000 mv/1000RPM C
Pulses per
revolution
PulPR The number of pulses per engine revolution when
using pulse feedback.

Gearbox type Gearb The type of demand to deliver to the gearbox:

1S - 1 solenoid

2S - 2 solenoid

3S - 3 solenoid

2I - 2 wire

Gearbox feedback
type
GbFbk The type of feedback from the gearbox:

No - None

1S - 1 signal

2S - 2 signal
C
Gearbox feedback
inversion
GbInv Set to invert the sense of the gearbox feedback. Setting
to 1 inverts the drive feedback, 2 inverts backflush, and
3 inverts both.

Swap drive and
backflush
GbSwp Set to reverse the sense of the gearbox drive. If set,
then the drive signal will be asserted when backflush is
demanded and vice-versa.
