C6: Carrier Frequency - YASKAWA CIMR-VU BA0001 Technical Manual

n C5-01/02: ASR Proportional Gain/Integral Time 1
These parameters determine the responsiveness of ASR at maximum output frequency.
• Increase the gain and/or reduce the integral time if the response is slow at maximum output frequency.
• Reduce the gain and/or increase the integral time when vibrations occur at the maximum output frequency.
• When adjusting ASR always first adjust the P gain, then adjust the integral time.
No.
C5-01
C5-02
n C5-03/04: ASR Proportional Gain/Integral Time 2
These parameters determine the responsiveness of ASR at the minimum output frequency. Use the same setting rules as
described for C5-01/02
No.
C5-03
C5-04
n C5-05: ASR Limit
Sets the ASR output limit as a percentage of the maximum output frequency (E1-04). If the motor slip is high, the setting
might need to be increased to provide proper slip compensation. Use the ASR output monitor U6-04 to determine if ASR is
working at the limit and make settings if necessary. If ASR is operating at the ASR limit, check the pulse signal and the pulse
input settings prior to changes in C5-05.

n C6-01: Drive Duty Selection
The drive has two different duty modes from which to select based on the load characteristics. The drive rated current, overload
capacity, and carrier frequency will change depending upon the duty mode selection. Use parameter C6-01 to select Heavy
Duty (HD) or Normal Duty (ND) for the application. The default setting is ND.
Ratings on page 342 for details about the rated current.
No.

<1> Model BA0018 does not have a Normal Duty mode. The default setting is 0.
