7.3.2.1 Functions
Functions
When the user selects PG vector control, it is necessary to select PG Card. The
function of PG card includes 2 ways of processing circuit for orthogonal encoder signal
and it can receive differential, open collector and push-pull output signal and the power
supply of the encoder (+12V); it can also output frequency division for the encoder
signal (the output is 2 ways of orthogonal open collector signal), so the user can select
according to the actual use.
