AC30V series Variable Speed Drive
PMAC Flycatching
Parameters::Motor Control::PMAC Flycatching
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’.
