When using the current input as

the frequency setting signal, set

"4" in any of Pr. 60 to Pr. 63

(input terminal function selection),

assign AU (current input selection)

to any of terminals RH, RM, RL and

STR, and turn on the AU signal.

*2 You can switch between the sink and source logic positions. For details, refer to the

instruction manual (detailed).

*3 When the setting potentiometer is used frequently, use a 2W1k

Ω

potentiometer.

*4 The terminal functions change with input terminal function selection (Pr. 60 to Pr. 63).

(Refer to page 38) (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).

selection)

CAUTION

•

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

(3.94inches) away from the power cables.
