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 VFD), 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.
