Note:
•
To use Speed Estimation Speed Search with V/f Control, do Rotational Auto-Tuning before you set the Speed Search function. If the
wire length between the drive and motor changed since the last time you did Auto-Tuning, do Stationary Auto-Tuning for Line-to-Line
Resistance process again.
•
If
A1-02 = 5, 6 [PM OLVector, PM AOLVector]
and the wiring distance between the motor and drive is long or if the motor is coasting
at more than or equal to 120 Hz, do not use Speed Search to restart the motor. Use Short Circuit Braking.
■
Current Detection 2
Use this Speed Search function with induction motors. Set
b3-24 = 2 [SpSrch Method Selection = Current Det2]
.
Current Detection Speed Search injects current into the motor to detect the speed of an induction motor. Speed
Search increases the output voltage for the time set in
L2-04 [Powloss Ramp Time@recovery]
, starting from the
maximum output frequency or the frequency reference.
