REMARKS

*1. The N/- terminal is not provided for the FR-S520E-0.1K to 0.75K-NA.

*2. The PR terminal is provided for the FR-S520E-0.4K to 3.7K-NA. (not used)

*3. You can switch the position of sink and source logic. Refer to page 23.

*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 98.) (RES, RL, RM, RH, RT, AU, STOP, MRS, OH, REX, JOG, X14, X16, (STR) signal selection)

*6. The terminal function changes according to the setting of output terminal function selection (Pr. 64, Pr. 65). (Refer to page 100.) (RUN, SU, OL, FU, RY, Y12, Y13, FDN, FUP, RL, Y93, Y95, LF, ABC signal selection)

CAUTION

To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.
