A.3.3 Wiring
Note:
A PG card signal line and a power line must be routed separately and disallow

parallel routing.
To avoid interference from encoder signals, use a shielded cable for the PG card

signal line;
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;
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;
