REMARKS

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

*2 You can switch between the sink and source logic positions. Refer to page 25.

*3 When the setting potentiometer is used frequently, use a 2W 1kΩ potentiometer. *4 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)

*5 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)
