The flycatching function enables the drive to be restarted smoothly into a spinning motor. It
applies small search voltages to the motor whilst ramping the Inverter frequency from maximum
speed to zero. When the motor load goes from motoring to regenerating, the speed search has
succeeded and is terminated. If the search frequency falls below the minimum search speed, the
speed search has failed and the Inverter will ramp to the speed setpoint from zero.
The flycatching sequence can be triggered by different starting conditions:
ALWAYS:
All starts (after controlled or uncontrolled stop, or after a power-up)
TRIP or POWER-UP: After uncontrolled stop, i.e. trip or coast, or after a power-up
TRIP:
After uncontrolled stop, i.e. trip or coast
The type of speed sequence may be Bidirectional or Unidirectional:
%LGLUHFWLRQDO
Initially, the search is performed in the direction of the speed setpoint. If the drive fails
to identify the motor speed in this direction, a second speed search is performed in the
reverse direction.
8QLGLUHFWLRQDO
The search is performed only in the direction of the speed setpoint.
ACTIVE
Range: FALSE / TRUE
A diagnostic output indicating whether the flycatching sequence is active.
SETPOINT
Range xxx.xx %
This diagnostic output is the setpoint caught at the end of a successful flycatching sequence.
