Note 1) Set = (ST: standby) and = (terminal board) for 3 wire operation. Assign HD
(operation hold) to any input terminal at input terminal selection. When assigning the S2 terminal
as shown above, set = (HD: operation hold).
Note 2) If the terminals are ON before turning on the power, terminal input is ignored when the power is
turned ON. (Prevents sudden movements.) After turning the power ON, turn terminal input ON
again.
Note 3) When HD is OFF, F and R are ignored even when ON. R does not operate even if it's ON when
HD is ON. Likewise in this state, F does not operate even if it's ON. Turn F and R OFF and then
turn them ON.
Note 4) During 3 wire operation, sending the jog run mode command stops operation.
