Parameter Descriptions
SEARCH VOLTS
PREF: 69.04 Default: 9.00 % Range: 0.00 to 100.00 %
The percentage level of the search volts applied to the motor during the speed search phase of the flycatching sequence.
Increasing this parameter improves the accuracy of the discovered motor speed but increases the braking influence of the speed
search on the rotating motor.
SEARCH BOOST
PREF: 69.05 Default: 40.00 % Range: 0.00 to 50.00 %
The level of search boost applied to the motor during the speed search phase of the flycatching sequence.
SEARCH TIME
PREF: 69.06 Default: 5.0 s Range: 0.1 to 60.0 s
The search rate during the speed search phase of the flycatching sequence. Performing the flycatching speed search too quickly
can cause the drive to inaccurately identify the motor speed. Refluxing at an inaccurate motor speed can cause the drive to trip
on overvoltage. If this occurs, increasing this parameter will reduce the risk of tripping.
MIN SEARCH SPEED
PREF: 69.07 Default: 5.0 Hz Range: 0.0 to 500.0 Hz
The lowest search speed before the speed search phase of the flycatching sequence is considered to have failed.
REFLUX TIME
PREF: 69.08 Default: 3.0 s Range: 0.1 to 20.0 s
The rate of rise of volts from the search level to the working level after a successful speed search. Refluxing the motor too
quickly can cause the Drive to trip on either overvoltage or overcurrent. In either case, increasing this parameter will reduce the
risk of tripping.
ACTIVE
PREF: 69.13 Default: FALSE Range: FALSE / TRUE
A diagnostic output indicating whether the flycatching sequence is active.
SETPOINT
PREF: 69.14 Default: —.xx % Range —.xx %
This diagnostic output is the setpoint caught at the end of a successful flycatching sequence.
