REMARKS
*1. The N/- terminal is not provided for the FR-S520E-0.1K to 0.75K.
*2. The PR terminal is provided for the FR-S520E-0.4K to 3.7K.
*3. Not needed when the setting dial is used for calibration.
Used when calibration must be made near the frequency meter for such a reason as a remote frequency meter.
However, the frequency meter needle may not deflect to full-scale if the calibration resistor is connected.
In this case, use this resistor and setting dial together.
*4. You can switch the position of sink and source logic. Refer to page 26.
*5. When the setting potentiometer is used frequently, use a 2W1k Ω potentiometer.
*6. The terminal functions change with input terminal function selection (Pr. 60 to Pr. 63). (Refer to page 102.)
(RES, RL, RM, RH, RT, AU, STOP, MRS, OH, REX, JOG, X14, X16, (STR) signal selection)
*7. The terminal function changes according to the setting of output terminal function selection (Pr. 64, Pr. 65).
(Refer to page 104.) (RUN, SU, OL, FU, RY, Y12, Y13, FDN, FUP, RL, Y93, Y95, LF, ABC signal selection)

When using the current input as
the frequency setting signal, set

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