				Using the parameter unit connection cable (FR-CB201 to

−−RS-485 connector 205), the parameter unit (FR-PU04) is connectable.

(*3)Communication operation can be performed through

RS-485.

*1. Do not connect terminals SD and PC each other or to the earth.

For sink logic, terminal SD acts as the common terminal of contact input. For source logic, terminal PC acts as the common terminal of contact input. (Refer to page 25 for the way to switch between them.)

*2. Low indicates that the open collector outputting transistor is on (conducts). High indicates that the transistor is off (does not conduct).

*3. Compatible with only the type having RS-485 communication function. (Refer to page 41.)

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

*5. RUN, SU, OL, FU, RY, Y12, Y13, FDN, FUP, RL, LF, ABC signal selection (Refer to page 90.)

*6. To be compatible with the European Directive (Low Voltage Directive), the operating capacity of relay outputs (A, B, C) should be 30V 0.3A DC.
