See Table 81 and Table 85
The default value and the max. value of carrier frequency (C001 and C002) depend on the drive size.
To check those values, see Table 81 and Table 85.
CAUTION
If the carrier frequency is changed via parameters C001 or C002, it is ad
visable to
adjust
the current control loop and the flux control loop of the VTC or FOC regulator
again (see “VTC” Control Algorithm and “FOC” Control Algorithm).
C001 Minimum Carrier Frequency
C001 Range
1600 ÷ 16000
Depending on the drive model
1600 ÷ 16000 Hz
Depending on the drive model – See Table 81
and Table 85
Default
See Table 81 and Table 85
Level
ENGINEERING
Address
1001
Function
This parameter represents the min. value of the modulation frequency being
used.
NOTE
The minimum value in C001 cannot exceed the maximum value in C002. If you want to
increase the minimum value and C001 and C002 are set the same value, it is necessary
to increase the maximum value in C002 before proceeding.
C002 Maximum Carrier Frequency
C002 Range
1600 ÷ 16000
Depending on the drive model
1600 ÷ 16000 Hz
Depending on the drive model – See Table 81
and Table 85.
Default
See Table 81 and Table 85.
Level
ENGINEERING
Address
1002
Function
This parameter represents the max. value of the modulation frequency being
used.
NOTE
The max. value set in C002 cannot be lower than the min. value set in C001. Decrease
the min. value in C001 if you need to decrease the max. value and if C001 equals C002.
NOTE
The max. value in C002 also determines the max. allowable speed value for the
selected motor, in order to ensure a minimum number of pulses per period of frequency
produced. This value is 16 for maximum carrier frequency (max. C002
value) greater
than 5kHz and 10 for lower maximum carrier frequency (see Table 81 and Table 85).
