Output Signal Setting - Mitsubishi Electric 800 Series Instruction Manual

(2) Outputting different selected signals from terminals AM2 and AM3 (Pr. 309 = "1 or 11")
START
Connect a DC ammeter across terminal
AM2 and terminal AC2 and across terminal
AM3 and terminal AC3 respectively.
Set "21" (reference voltage output) in Pr.
306 and Pr. 310.
Terminal AM2
Use Pr. 900 to set
END
In Pr. 306 and Pr. 310, set the types of the signals to be output. (refer to the Instruction Manual(Detailed))
NOTE
• If calibration is made without setting "21" (reference voltage output) in Pr. 306 and Pr. 310, terminals FM/CA, terminal
AM of the inverter is calibrated. To calibrate the extension analog output, always set "21" in Pr. 306 and Pr. 310.
• When a plug-in option (FR-A8AN) has been re-fitted to other inverter, calibrate again.
4.4.3

Output signal setting

Set the output signals to be monitored. Set Pr. 306 to output the same signal from terminals AM2 and AM3 and Pr. 306 and Pr.
310 to output different signals. The settings of Pr. 306 and Pr. 310 are the same as those of Pr.54 FM/CA terminal function
selection and Pr.158 AM terminal function selection. For the details of Pr.54 and Pr.158, refer to the Instruction Manual
(Detailed) of the inverter.

ANALOG CURRENT OUTPUT
At this time, check that the polarity is correct
At this time, the following analog signal is actually output, swinging the
meter needle.
Maximum output current set previously (factory setting: 20mADC)
Terminal AM3
Use Pr. 901 to set
After making adjustment with
press
for the meter needle to swing full scale,
to set.
