AC30 series Variable Speed Drive
Flycatching
Parameters::Motor Control::Flycatching
Only available if IM MOTOR selected in
Control Mode
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’.
