Related Functions: FU2-22 ~ FU2-25 [Speed Search]

FU2-22: Speed Search Selection (Bit Set)

FU2-23: Current Limit Level During Speed Search

FU2-24: P Gain During Speed Search

FU2-25: I Gain During Speed Search

This function is used to permit automatic restarting after Power ON, Fault Reset, and Instant Power Failure without waiting for the motor to stop.

The speed search gain should be set after considering the inertia moment (GD2) and magnitude of torque of the load. FU2-37 [Load

Inertia] must be set at the correct value to make this function operate correctly.

FU2-23[Current Limit Level] is the current that the inverter limits its current rise during speed searching. (The set value is the percentage of FU2-33 [Rated Motor Current])

FU2-24[P Gain] is the proportional gain used for speed search. Set this value according to load inertia set in FU2-37.

FU2-25[I Gain] is the Integral gain used for speed search. Set this value according to load inertia set in FU2-37.
