Flycatching
Parameters::Motor Control::Flycatching
This feature performs a directional speed search. It allows the Drive to seamlessly catch a spinning motor before controlling the motor to the
desired setpoint. This is especially useful for large inertia fan loads, where drafts in building air ducts can cause a fan to `windmill'.

Parameter Descriptions
0310
VHz Flying Start Enable
Enable flycatching in V/Hz control mode when TRUE
0311
VC Flying Start Enable
Enable flycatching in Vector control mode when TRUE
0312
Flying Start Mode
Mode of operation - V/Hz control
Enumerate Value: Flying Start Mode
0: Always
1: Trip or Power up
2: Trip
0313
Search Mode
The type of speed search carried out by the flycatching sequence.
Enumerated Value : Search Mode
0 : BIDIRECTIONAL
1 : UNIDIRECTIONAL
0314
Search Volts
Only under VHz control
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.
0315
Search Boost
Only under VHz control
The level of search boost applied to the motor during the speed search phase of the flycatching sequence.
0316
Search Time
Only under VHz Control
AC30V series Variable Speed Drive
D-41
