4 to 20mADC(+)
When using current input as the
frequency setting signal, set "4" in
any of Pr.180 to Pr.183 (input
terminal function selection) and
assign AU (current input selection)
to any of terminal RH, RM, RL, or
MRS, then turn the AU signal on.
Note: 1. If the potentiometer is to be operated often, use a 2W1kΩ potentiometer.
2. 0.1K and 0.2K do not contain a transistor.
3. Terminals SD and SE are isolated.
4. Term inals S D and 5 are co m m on term inals. D o not earth (ground) them to the
ground . Term inals S D and 5 are not isolated. (Those of the 400V class are isolated.)
5. When terminals PC-SD are used as a 24VDC power supply, be careful not
to short these terminals. If they are shorted, the inverter will be damaged.
6. N ot needed w hen the operation panel or param eter unit (FR -PU 04) is used for
calibration. U sed w hen calibration m ust be m ade near the frequency m eter for
such a reason as a rem ote frequency m eter. H ow ever, the frequency m eter
needle m ay not deflect to full-scale if the calibration resistor is connected. In this
case, use this resistor and the operation panel or param eter unit together.
