5.3 Protection and
information
Protection of the motor and of the CDA3000 inverter module is preset
depending on the power class of the module. By means of parameter set-
ting the protection can be adapted for special applications and the protec-
tion zone made more sensitive. These safety devices are indicated by
warning and error messages. As an aid to setup, indications of the current
actual values and of the device capacity utilization can be obtained in the
form of a peak value memory.
A special case is power failure bridging, which can be parameterized in
response to infringement of a minimum voltage at the mains voltage
input.
