･
For wiring between the PG and the inverter, use a shielded cable. It is recommended that the shielded layer be connected to the [CM] terminal on the
card and be open at the PG side.
･
If the wiring between the PG and the inverter is long, interference of A- and B-phases may cause PG signal malfunctions, resulting in abnormal
noise or torque pulsation. In such a case, minimizing the wiring length (by reviewing the wiring route) or using a cable with smaller stray
capacitance may reduce the problem.
･
When using an inverter internal power supply, set a jumper cap at the INT side on jumper J1; when using an external power supply, at the EXT side.
･
If malfunctioning due to noise causes a problem, winding the shielded cable around a ferrite core by one or two turns may reduce the problem.
･
Mounting this interface card disables the pulse train input function assigned to the inverter's [X7] terminal.
