FLYCATCHING
SETUP::MOTOR CONTROL::FLYCATCHING
Designed for all Motor Control Modes.
This block 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'.
