Carrier Frequency
Setting Error
1. Contradictory settings
· C6-03 (Carrier Frequency
Proportional Gain)>6
· C6-02 (Minimum Carrier
Frequency)> C6-01
(Maximum Carrier
Frequency)
Note: If C6-03 ≤ 6 , the drive
operates at C6-01
2. The upper and lower limit
set in C6-00 to C6-03 are
contradictory.
Correct the parameter setting.
Improper setting of
motor rated speed
1. The following is also set.
· C6-03 (carrier frequency
proportional gain) >6
· C6-02 > C6-01
(lower carrier frequency >
upper carrier frequency)
(Note) When C6-03 ≤ 6, press
the fixed value of C6-01
2. The upper and lower limits
of C6-00~-03 are set
incorrectly.
Correct the parameter setting.
