Range
1.6.t (θ) Theta offset (°)
Offset value (°) around the horizontal axis of gyro
sphere (rotor axis) and the sensitive element.
0.00 -3.00 – 3.00
1.7.G X signal pickup gain (v/°)
Distance of the sensitive element share and the rotor
axis direction. Inclination angle around horizontal axis
is obtained equivalently by monitoring this signal. For
example, when north side of the rotor axis rises, the
sensitive element follows to rise its north side, then
gyro sphere suspended by the suspension wire moves to
south side. X signal represents this amount of
movement (v/°).
This parameter is only used for GC85.
2.32 0.00 – 5.00
1.8.c Ks/H
Suspension wire twist torque. Fixed value.
1.477 1.000 – 2.000
1.9.r Maximum rate of turn (°/sec)
Maximum rate of turn in the turn rates which the
b
earing servo system followed up to this moment
(°/sec).
NOTE:
The maximum is measured after 3 hours from
system start.
NOTE:
Reset this data certainly after completion of
installation!
0.00 -
1.A.F Maximum deviation of bearing servo (°)
Maximum deviation value in the bearing servo loop that
occurred up to this moment (°).
NOTE:
The maximum is measured after 3 hours from
system start.
NOTE:
Reset this data certainly after completion of
installation!
0.00 -
1.b.S Maximum deviation of horizontal servo (°)
Maximum deviation value in the horizontal servo loop
that occurred up to this moment (°).
NOTE:
The maximum is measured after 3 hours from
system start.
NOTE:
Reset this data certainly after completion of
installation!
