Detection Of Control Circuit Temperature - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

• The inverter does not stop cumulating (can continue to cumulate) the output energy even if the retry function or the
automatic restart after instantaneous power failure function works because the cause of the function activation is a mini
power failure which is too short to cause an inverter reset.
• If a power failure occurs, the cumulative value is reset to 0 kWh and restart cumulating.
• To use the Y79 signal, set "79 (positive logic) or 179 (negative logic)" in any of Pr.190 to Pr.196 (Output terminal function
selection) to assign the function to the output terminal.

NOTE
• Because the accumulated data in the inverter is cleared when control power is lost by power failure or at an inverter reset, the
value on the monitor cannot be used to charge electricity bill.
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal. (Refer to
• Do not assign the signal to terminal ABC1 or terminal ABC2 whose pulse outputs are frequently turned ON/OFF. Otherwise,
the life of the relay contact may be shortened.

5.11.14 Detection of control circuit temperature

The temperature of the control circuit board can be monitored, and a signal can be output according to a predetermined
temperature setting.

 Control circuit temperature monitoring
• The temperature of the control circuit board can be monitored within the range of 0 to 100°C on the operation panel, or via
terminal FM/CA, or terminal AM. Refer to
• When Pr.290 Monitor negative output selection is set to enable display of the negative numbers for monitoring on the
operation panel or via terminal AM, the range of monitoring is -20 to 100°C.
• The monitor value is a rough approximation of the change in the surrounding air temperature of the inverter. Use this
parameter to grasp the operating environment of the inverter.
 Control circuit temperature detection (Pr.663, Y207 signal)
• The Y207 signal can be output when the control circuit temperature reaches the Pr.663 setting or higher.
• To use the Y207 signal, set "207 (positive logic) or 307 (negative logic)" in any of Pr.190 to Pr.196 (Output terminal
function selection) to assign the function to the output terminal.
NOTE
• The Y207 signal is turned OFF when the control circuit temperature becomes 5°C or more lower than the Pr.663 setting.
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
