GROUP – 5: SKIP FREQUENCY
B501: Skip Frequency 1 (Hz)
B502: Skip Frequency 2 (Hz)
B503: Skip Frequency 3 (Hz)
B504: Skip Band (Hz)
If the equipment being driven has problems due to mechanical resonance at some frequencies, the
same can be jumped over by programming them in parameters B501 ~ B503. The AC DRIVE output
settles for top or the bottom of the skip band, the one being closest to the desired speed. This is only
applicable during normal operation of the AC DRIVE. During acceleration or deceleration this
parameter will not function.

GROUP – 6: VECTOR CONTROL CONSTANTS-1
B601: Speed Loop Time (mS)
It is a time at which the speed control loop will execute. This parameter is used to adjust the speed
control loop bandwidth. Default value is changed for vector control open or close loop mode.
B602: ASR P-Action Control (%)
If the speed setting value or motor speed changes suddenly, this will prevent sudden change in the
output of proportional control of ASR.
