AU (current input selection) to any		Earth (Ground)
of terminals RH, RM, RL and STR,
and turn on the AU signal.

REMARKS

*1 Only the type with RS-485 communication function.

*2 Not needed when the setting dial is used for calibration. This resistor is used when calibration must be made near the frequency meter for such a reason as a remote frequency meter. Note that the needle of the frequency meter may not deflect to full-scale when the calibration resistor is connected. In this case, use both the resistor and setting dial for calibration.

*3 You can switch between the sink and source logic positions. Refer to page 25. *4 When the setting potentiometer is used frequently, use a 2W1kΩ potentiometer. *5 The terminal functions change with input terminal function selection (Pr. 60 to

Pr. 63). (Refer to page 38, 88) (RES, RL, RM, RH, RT, AU, STOP, MRS, OH, REX, JOG, X14, X16, (STR) signal selection)

*6 The terminal functions change with output terminal function selection (Pr. 64, Pr. 65). (Refer to page 90) (RUN, SU, OL, FU, RY, Y12, Y13, FDN, FUP, RL, LF, ABC signal selection)
