Faults F0011 Function chart number: MICROMASTER 420 has a completely new integrated concept for thermal motor protection. There are numerous possibilities of effectively protecting the motor but at the same time ensuring high motor utilization. The basic philosophy of this innovative concept is to detect critical thermal states, output warnings and initiate the appropriate responses.

The specified circuit examples apply for the PTC temperature sensor from the M11 Motor Catalog (motor protection using PTC thermistors, Code Z = A10 – A16) - that is used for the 1LA and 1LG Siemens motors. NOTE In order to avoid noise from being coupled into the drive inverter electronics - with the associated disturbances - none of the free conductors in the motor cable may be used to connect the temperature sensor to the drive inverter.
"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. MICROMASTER 420 Operating Instructions 6SE6400-5AA00-0BP0...
However, the possibilities of assigning parameters only involves interventions below the shutdown threshold which cannot be changed by users. MICROMASTER 420 has the following thermal monitoring functions: Heatsink temperature The monitoring of the heatsink temperature r0037[0] of the power semiconductor (IGBT).

When the output frequency is reduced, this significantly reduces the drive inverter output current and in turn reduces the losses in the power module. MICROMASTER 420 Operating Instructions 6SE6400-5AA00-0BP0...

NOTE If the drive inverter fan fails, this would be indirectly detected by the measurement of the heatsink temperature. A wire breakage or short circuit of the temperature sensor(s) is also monitored. MICROMASTER 420 Operating Instructions 6SE6400-5AA00-0BP0...
In order to keep the flux constant, when frequency f changes, the voltage V must be changed in proportion so that a constant magnetizing current I flows. The V/f characteristic control is derived from these basic principles. MICROMASTER 420 Operating Instructions 6SE6400-5AA00-0BP0...
