Cause : Carrier Frequency Setting Error comes when the following simultaneous contradictory settings: C6-05 is greater than 6 and C6-04 is greater than C6-03 (carrier frequency lower limit is greater than the upper limit). If C6-05 is less than or equal to 6, the drive operates at C6-03.

1. Upper and lower limits between C6-02 and C6-05 contradict each other.
2. Correct the parameter settings.
