Note
● Setting of jumpers takes top view with main terminals at the bottom of the
card as visual angle. Jumpers are silk-screened on the card.
● When using CANlink or Modbus protocol for communication, match
terminal resistor to the end AC drives by setting jumpers J4 or S2. The
J4 or S2 of the middle AC drives must keep default state. If J4 or S2 is
set improperly, instable communication or communication failure will
be caused and Err16 or Err55 will be detected.
