5.3 C: Tuning
Setting a Variable Carrier Frequency (V/f Control only)
In V/f Control, the carrier frequency can be set up to change linearly with the output frequency. In this case the upper and
lower limits for the carrier frequency and the carrier frequency proportional gain (C6-03, C6-04, C6-05) have to be set as
shown in Figure 5.31.
K is a coefficient determined by the value of C6-03:
• 10.0 kHz > C6-03 ≥ to 5.0 kHz: K = 2
• 5.0 kHz > C6-03: K = 1
• C6-03 ≥ 10.0 kHz: K = 3
Note: 1. A carrier frequency error (oPE11) will occur when the carrier frequency proportional gain is greater than 6 while C6-03 is less than
C6-04.
2. When C6-05 is set lower than 7, C6-04 is disabled and the carrier frequency will be fixed to the value set in C6-03.
n Rated Current Depending on Carrier Frequency
The tables below show the drive output current depending on the carrier frequency settings. The 2 kHz value is equal to
the Normal Duty rated current, the 8/10 kHz value is equal to the Heavy Duty rated current. The carrier frequency
determines the output current linearly. Use the data below to calculate output current values for carrier frequencies not
listed in the tables.
Note: In Heavy Duty mode the maximum rated output current is equal to the 8/10 kHz value, even if the carrier frequency is reduced.
