•Detecting Speed Difference between the Motor and Speed Reference (F1-04, F1-10
and F1-11)
Speed deviation is detected when the speed deviation (i.e., the difference between the speed reference and the
actual motor speed) is too large. Speed deviation (DEV) is detected only after a speed agreement (speed reference
and actual motor speed are within the setting range of L4-02) and if a speed deviation higher than the set
value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the Inverter
stops according to the setting in F1-04.
