Operation
of a module the voltage of this capacitor changes along with its charging condition,
too. This voltage is collected by the module, can be equipped with an offset
(zk_vcko), is then amplified (zk_vckp), and possible filtered (zk_vckt) (Fig. 5).

Monitoring Functions / Shutdowns on Faults
The module is equipped with numerous monitoring functions that are explained in the
following. If there is a fault shutdown executed, the corresponding bits (see table
below) are set in the variable mod_state. Before the module can be restarted, the
faults occurred have to be acknoweldged by setting the variable err_quit to 1.
Overcurrent
 "I_VS too high"
Is indicated when the hardware overcurrent shutdown was activated.
Overtemperature
 "Overtemperature“
For the overtemperature shutdown, the temperature of the heat sink element is
monitored. At a temperature of more than 90 °C at the heat sink element, the
shutdown is carried out with an error message.
Overvoltage at the DC link
 "U_ZK too high“
If the DC link voltage exceeds 400V, there is a fault shutdown carried out.
In the full range DC link voltage mode, there is an additional shutdown carried out if
the DC link voltage exceeds the value 1,5*zk_usollvh.
Undervoltage at the DC link
 "U_ZK too low“
In the normal range DC link voltage mode, there is a shutdown carried out because of
DC link undervoltage at 351V.
In the full range DC link voltage mode a shutdown is carried out if the DC link voltage
is smaller than 6V below the bottom desired value zk_usollvl.
If during the initial charging of an empty DC link the desired DC link voltage is not
reached after a certain period, the module also shuts down with an error message.
