11.1.2 Incremental encoder card

Note: The lower pins of CN3 are valid if incremental encoder PG card is used on Goodrive3000 series products.
11.1.2.1 Introduction
A PG card is a must for PG vector control. The PG card functions include processing circuits for two quadrature encoder
signals and supporting spindle positioning Z signal inputs, and receiving signals of differential, open collector and
push-pull encoder. Frequency-divided output can be performed for the input encoder signals. The output quantity includes
two channels of differential signals. You can choose to output push-pull signals or open collector signals through jumper
J1 or J2 according to your actual use.
11.1.2.2 Terminal and DIP switch
The incremental encoder PG card has two 2*4P user wiring terminals. See the figure.

PWR
PWR and COM1 are for encoder working power output; IA+, IA-, IB+, IB-, IZ+, and IZ- are encoder signal input terminals;
OA+, OA-, OB+, OB- are differential crossover signal output terminals, while OA, OB, and COM1 are frequency-divided
push-pull signal and open collector signal output terminals (the output signal type is selected by jumper J1 or J2); the PG
card does not connect PE to the earth internally, you can ground it during use.
The frequency division coefficient of the incremental encoder PG card is determined by the dip switch on the card. The dip
switch have 8 bits, and the frequency division coefficient is determined by adding 1 to the binary number that the dip
switch represents. The place labeled with "1" is the low binary bit, and the one labeled with "8" is the high binary bit. When
the dip switch is turned to ON, the bit is valid, indicating "1"; otherwise, the bit indicates "0". See the following table for
frequency division coefficients.
