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.
Pr.
663 Control circuit temperature
M060 signal output level
 Control circuit temperature monitoring
• The temperature of the control circuit board can be monitored within the range of 0°C 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°C 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 parameter from 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.
