8.3 Monitoring of the heatsink temperature
In order to avoid impermissible heating of the device, the heatsink temperature is detected and
monitored.

Note!
In the temperature range 0 ... 80 °C, the heatsink temperature is measured with a
tolerance of -2 ... +4 °C. Outside this temperature range, the measuring accuracy
strongly decreases.

Subindex 2: Heatsink temperature: Warning threshold
Warning threshold for temperature monitoring
• If the heatsink temperature exceeds the threshold value set here, the device reports a warning. The warning
message is reset with a hysteresis of approx. 5 °C.
• If the heatsink temperature increases further and exceeds the non-adjustable error threshold (100 °C), the
device changes to the "Fault" device status. Further operation of the i700 servo inverter is disabled by controller
inhibit.
