Subindex 3: Heatsink temperature: Threshold for fan switch-on
Switch-on threshold for device fans
• If the heatsink temperature exceeds the threshold value set here, the device fan is switched on. This also
happens if the switch-off threshold is parameterised higher than the switch-on threshold by mistake.
• In order to activate the fan, the switch-on and switch-off threshold can be set to the maximum value as then the
device simultaneously switches to the "Fault" status.
• Bigger designs of the Servo-Inverter i700 are provided with an internal fan. This is triggered at the same time as
the heatsink fan and does not have internal switch-on or switch-off thresholds.
Note!
Increasing the switch-on threshold can cause higher device temperatures. This may reduce the service life of the
device!

Subindex 4: Heatsink temperature: Threshold for fan switch-off
Switch-off threshold for device fans
• If the heatsink temperature falls below the threshold value set here, the device fan is switched off. This only
happens if the switch-off threshold is parameterised lower than the switch-on threshold.
• Bigger designs of the Servo-Inverter i700 are provided with an internal fan. This is triggered at the same time as
the heatsink fan and does not have internal switch-on or switch-off thresholds.
