Carrier Frequency Selection
Sets the carrier frequency for the transistors in the drive.
1 : 2.0 kHz
2 : 5.0 kHz
3 : 8.0 kHz
4 : 10.0 kHz
5 : 12.5 kHz
7 : Swing PWM1 (Audible Sound 1)
8 : Swing PWM2 (Audible Sound 2)
9 : Swing PWM3 (Audible Sound 3)
A : Swing PWM4 (Audible Sound 4)
B : Leakage Current Rejection PWM
F : User Defined (C6-03 to C6-05)
Note:
•
The carrier frequency for Swing PWM 1 to 4 is equivalent to 2.0 kHz. Swing PWM applies a
special PWM pattern to decrease the audible noise.
•
Setting
B
uses a PWM pattern that decreases the leakage current that the drive detects over long
wiring distances. This can help decrease alarm detection and decrease problems with the current
monitor from leakage current over long wiring distances.
