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.

(5) Wiring principles
(6) Wiring precautions
① A PG card signal line and a power line must be routed separately and disallow parallel routing.
② To avoid interference from encoder signals, use a shielded cable for the PG card signal line.
③ The shield layer of the encoder shield cable should be connected to the earth (such as the PE of
Goodrive800 Pro series product), and it must be connected to earth only at one end to avoid signal
interference.
④ If the PG card uses frequency-divided output when connecting to an external power supply, the voltage
should be less than 24V; otherwise the PG card will be damaged.
⑤ You can set the output voltage by adjusting the 12–15V incremental encoder PG card potentiometer
(clockwise for voltage increases) according to actual needs, and the force should not be too great when
rotating the potentiometer.
