Power module protection

3.21.1

General overload monitoring

Parameter range:
Warnings
Faults
Function chart number:
Just the same as for motor protection, MICROMASTER provides extensive
protection for the power components. This protection concept is also sub-divided
into 2 levels:
Warning and response
Fault and shutdown
Using this concept, a high utilization of the power module components can be
achieved without the drive inverter being immediately shut down. The power
module components are monitored as follows:
Table 3-22
Overcurrent / short circuit
DC link overvoltage
DC link undervoltage
Line phase failure detection
(refer to P0291)
The monitoring thresholds for the righthand column in the table above are
permanently saved in the drive inverter and cannot be changed by the user. On the
other hand, the threshold levels for the "Warning and response" column can be
modified by the user to optimize the system. These values have default settings so
that the "Fault and shutdown" thresholds do not respond.
