C6 Carrier Frequency - YASKAWA VS-616G5 Series Programming Manual

C5-08 ASR Integral Limit
Setting Range:
Factory Default:
.Parameter C5-08 adjusts the amount of Integral control of the automatic speed regulator in the Closed
Loop Flux Vector control mode. Setting parameter C5-08 to zero will make the ASR control propor-
tional. Setting C5-08 to 400% will make the ASR control proportional and integral.
C6 Carrier Frequency
This function sets the inverter output transistor switching frequency (carrier frequency). Increase the
carrier frequency to reduce motor noise and decrease it to reduce leakage current.
C6-01 Carrier Frequency Upper Limit
C6-02 Carrier Frequency Lower Limit
Setting Range:
Factory Default:
For constant carrier frequency operation, set the gain (C6-03) to "0", and set the upper limit (C6-01)
and lower limit (C6-02) to the same value.
* Factory defaults vary depending on drive rating. See the following table for more details:
