Tip Strip: H-Bridge channel 1 stiction compensation value
Units: V
Detail: Specifies Voltage added to or subtracted from the PID output when Primary Position is outside the vicinity of
LH Position.
US_ChX
is intended to compensate for valve stiction. This parameter assists throttle control during
small position errors to overcome stiction. Parameter
uFc_ChX
is updated to a positive or negative value according
to the sign of Position Setpoint - Primary Position error, and added to the PID output.
USLag_ChX
Tip Strip: H-Bridge channel 1 lag filter time for stiction compensaton
Units: s (seconds)
Detail:
Specifies lag filter time applied to the stiction compensation. A lag time prevents
uFc_ChX
from reversing
directions too fast.
LHPsn_ChX
Tip Strip: H-Bridge channel 1 limp home angle
Units: % or deg
Detail: Specifies the default throttle position which results from no power being applied to the motor. If this
parameter is not known, it can be set to any value and the Position Calibration process must be executed. The
calculated LH Position
LHPsn_Out_ChX
will be updated
in the Control Calibration Out column.
MotorResistance_ChX
Tip Strip: H-Bridge channel X motor resistance
Units: Ohms
Detail: Specifies the resistance of the motor winding. A digital multi-meter (DMM) can be used to measure this. This
value is used to determine safe output ranges.
