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

Control circuit temperature monitor
• The operation panel can be used to monitor the temperature of the control circuit board within the range of 0 to 100°C.
• The range becomes -20 to 100°C by setting the display with a minus sign in Pr.290 Monitor negative output selection.
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.195 (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.195 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

• The Fault (ALM, ALM2) signals are output when the converter
unit protective function is activated.
• The ALM2 signal stays ON during the reset period after the fault
occurs.
• To use the ALM2 signal, set "94 (positive logic) or 194 (negative
logic)" in any of Pr.190 to Pr.195 (Output terminal function
selection) to assign the function to the output terminal.
• The ALM signal is assigned to the A1B1C1 contacts in the initial
status.
