5.8 (M) Monitor display and monitor output signal
5.8.14 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 monitor
• The operation panel, terminal CA, or terminal AM can be used to monitor the temperature of the control circuit board within
the range of 0 to 100°C. (Refer to page 274 for information on how to select the monitor item.)
• When monitoring with the operation panel or terminal AM, the range becomes -20 to 100°C by setting the display/output
with a minus sign in Pr.290 Monitor negative output selection.
• 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.
• For the Y207 signal, set "207 (positive logic) or 307 (negative logic)" in one of Pr.190 to Pr.196 (Output terminal function
selection) to assign the function to the output terminal.
• 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.
