Mitsubishi Electric FR-A820-00046 (0.4K), Instruction Manual

Page: 752 / 1218

(A) Application parameters Parameters
5 - 550
Selection of deviation value, measured value and set point input method, and PID action
method (Pr. 128, Pr. 609, Pr. 610)
●
Using Pr. 128, select the input method for the PID set point, measured value detected by the meter,
and externally calculated deviation. Also, select forward or reverse action.
●
Switch the power voltage/current specifications of terminals 2 and 4 by Pr. 73 "Analog input
selection" or Pr. 267 "Terminal 4 input selection" to match the specification of the input device.
After changing the Pr. 73 and Pr. 267 settings, check the voltage/current input selection switch.
Incorrect setting may cause a fault, failure or malfunction. (Refer to page page 5-406 for the
setting.)
When Pr. 133
≠
"9999", the Pr. 133 setting is valid.
For the details of CC-Link communication, refer to the Instruction Manual of the option FR-A8NC,
FR-A8NCE.
For the details of the PLC function, refer to the PLC Function Programming Manual.
