Recommended Encoder and Its Wiring
For the pulse train input function of the 3G3M1 Series inverter, be sure to use a complementary output
type encoder.
In addition, for encoder cable connection, always use a shielded cable and connect it to the DIC termi-
nal of the inverter’
s control circuit terminal block.
If an open collector output encoder is used, the inverter may not recognize the rotation in the forward
or reverse direction. This is because, as the length of the encoder cable increases, its stray
