AFE Start Up Sequence
In order to minimise the potential occurrence of initial current transients when AFE is switched on, an "AFE Start Settings" block was included in the
default macro. It works in conjunction with the following four soft parameters:
-
1943 AFE Current Limit
-
1944 AFE Current Loop P Gain
-
1945 AFE Stack Frequency
-
1946 AFE Default Stack Frequency
AFE Default Macro Setup Parameters
These soft parameters have to be populated with the values that are required for operation in normal running mode, before first start of AFE mode is
attempted!
Start up values are set as constants within the macro, and can only be changed by reprogramming AFE application into the drive. Soft parameter
1946 AFE Default Stack Frequency allows the user to specify if drive should operate (post start up) with its default switching frequency, or with a
different one, as specified in soft parameter 1945.
It is, by default, set that start up is finished after 1.5 seconds since the run command has taken effect.
