4.3 Terminal connection diagram

(Note 1) : Please refer to the instruction manual of the inverter main body about the wiring of the
logic board.
(Note 2) : Use a twisted and shielded wire for the signal cables, and cut the shielded covering as
shown in the diagram below. Make sure that the length of the signal cable is 20 meters
or less. If the length exceeds 20 meters, please use a VX application control device
RCD-E (remote control device) or CVD-E (insulation signal) to avoid malfunction
caused by EMC noise or voltage drop. Also, electric wire for the encoder uses twist
shield line of 0.75mm
the distance less than 20m. In case of more than 20m, please use the relay amplifier of
the 5V line driver specification output.
