EXTENSION ANALOG OUTPUT
(2) Outputting different select signals from terminals AM0 and AM1 (Pr. 309 = 1 or 11)
START
Connect a DC voltmeter (or DC ammeter) across terminals AM0 (or terminal AM1) and AMC.
Use Pr. 323 (or Pr. 324) to calibrate the meter when the voltage (current) input is 0.
Set "21" (reference voltage output) in Pr. 306 and Pr. 310.
At this time, check that the polarity is correct
If the meter needle does not point to 0 when voltage or current input is 0, use Pr. 323 AM0 0V adjustment or Pr. 324 AM1 0mA adjustment to calibrate the meter
At this time, the following analog signal is actually output and deflects the meter.
<across terminals
Maximum output voltage set previously (factory setting: 10VDC) 
<across terminals
Maximum output current set previously (factory setting: 20mADC)
| Run the inverter |
| The inverter may be run in either the PU or external operation mode. |

to set.
In Pr. 306 and Pr. 310, set the types of the signals to be output.
(Refer to page 18.)
CAUTION
1.If calibration is made without "21" (reference voltage output) set in Pr. 306 or Pr. 310, terminals FM/AM of the inverter is calibrated. To calibrate the extension analog output, always set "21" in Pr. 306.
