9.1.2.3 Wiring diagram
9.1.2.4 Wiring notes
①The signal line of PG card should be separated from the power line. Parallel wiring is forbidden.
②Select shielded cables as the signal lines of PG card to prevent coder signals from disturbance.
③The shielding layer of shielded cable of PG card should be grounded (such as terminal PE of
the inverter), and furthermore, only one end is grounded, to prevent signal from disturbance.
④If the frequency-division output of PG card is connected to the user power supply, the voltage
should be less than 24V; otherwise, the PG card may be damaged.
⑤Users can adjust the potentiometer and set output voltage according to actual requirements.
Do not rotate the potentiometer with too much force.
