§
PG-B2 (For Flux Vector Control Mode Only)
•
Shielded twisted-pair wires must be used for signal lines.
•
Do not use the PG’s power supply for anything other than the PG. Using it for another
purpose can cause malfunctions due to noise.
•
The length of the PG’s wiring must not be more than 100 meters (328 feet).
•
The direction of rotation of the Inverter can be set in user constant F1-05. The factory preset
if for forward rotation, A-Phase advancement.
