VLT ® 2900 Series in Closed loop is programmed in parameter 416 Proc- ess units . Set the required value within the feedback range (pa- rameter 414 Minimum feedback, FB MIN and 415 Max- imum feedback, FB MAX ). 0 (OFF) - 100 Hz 0 Hz Some systems call for some output frequencies to be avoided because of mechanical resonance problems in the system. In parameters 230-231 Frequency by- pass these output frequencies can be programmed. In this parameter a bandwidth can be defined on either side of these frequencies. The frequency set in this parameter will be centered around parameters 230 Frequency bypass 1 and 231 Frequency bypass 2 .
