Parameter descriptions
580 Reduction Limit Ti/Tc
The change of the switching frequency depends on the heat sink temperature switch-off limit and the
output current. The temperature limit to be exceeded so that the switching frequency is reduced can

580 Reduction Limit Ti/Tc
The limit for the switching frequency reduction is influenced by the intelligent current
limits depending on the selected
have been switched off or provide the full overload current, the switching frequency is
reduced when the output current exceeds the limit of 87.5% of the long-term over-
load current (60 s). The switching frequency is increased if the output current drops
below the reference current of the next highest switching frequency.

7.10.2 Fan

39 Switch-On Temperature
The fans run in two power stages.
The fans ar switched on with the following conditions:
If the inside, capacitor or heat sink temperature exceeds the value of
•
39, the inside fan and the heat sink fan will be switched on and run at half power.
A possible external fan is also switched on via the parameterized digital output.
• Independent of the setting of
internal fixed temperature thresholds (internal temperature, Capacitor temperature) haven
been reached.
If the measured temperatures increase also at half power of the fans, the fans will be
•
switched to full power when a critical temperature threshold is reached.
To protect the device a device fault is triggered when reaching an internal switching
off temperature threshold.
The fans will be switched off again as soon as the heat sink temperature has dropped below the
Switch-On Temperature
switch-on thresholds.

Further fan control setting options
Operation mode "43 - external fan" for digital outputs additionally enables the control of an external
fan. Via the digital output, the external fan is switched on as soon as the
