All of the MC58113 parameters described in this section can be conveniently specified using Pro-Motion via the Axis
Wizard. See

2.4.2
Overtemperature Protection
The DK58113 uses a temperature sensor to continuously monitor the temperature of the on-card power MOSFETs.
2.4.2.1
Converting Temperature Readings into Degrees C
The MC58113 IC inputs temperature readings via its Temperature analog input and performs related functions such
as over temperature checking without converting the readings from the attached temperature sensor into degrees C.
It does this by comparing temperature in units of ‘counts,’ meaning the numerical value of the Temperature signal
converted by the MC58113’s on-chip A/D.
While using Pro-Motion however, it is convenient to be able to view and trace the amplifier temperature in units of
degrees C. This is accomplished by providing a conversion table to Pro-Motion.
Note that use of this table is optional and is only required if display of temperature via Pro-Motion is desired with
units of degrees C. In any case, for the DK58113, the table “DK58113 Temp Table.txt” should be selected.
2.4.2.2
Temperature Limit
The following temperature limit is required to safely operate the DK58113 board.
If an Atlas amplifier is used these temperature limit values do not need to be specified.
All of the MC58113 parameters described in this section can be conveniently specified using Pro-Motion via the Axis

Temperature limit
75.0 C
This value should be entered to ensure that the amplifier
does not operate above the maximum safe temperature
The DK58113’s temperature sensor is located on the DK58113 board and therefore will not function correctly
when a remote amplifier is used.
