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 Open Loop Vector, PM Advanced Open Loop Vector]
and the wiring distance between the motor and drive is long or if
the motor is coasting at more than or equal to 200 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 [Speed Search Method Selection = Current
Detection 2]
. 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 [Powerloss V/f Recovery Ramp Time]
, starting
from the maximum output frequency or the frequency reference.
