7 Drive Machine Data (SIMODRIVE Drive MD) 10.94
7.1.2 MSD MD (data description - SW 3)
Maximum motor temperature motor 1 63
Default value Lower input limit Upper input limit Units
Depends on motor 0 170 °C
Active
at once
Input of maximum motor temperature. The value entered can be lower than the maximum
temperature value calculated via the motor code number (MD 96) and motor data set. If the
specified temperature is exceeded, the "Motor overtemperature" prewarning is output after
approximately 30 s (provided it is activated) or the "Motor overtemperature" alarm given after
the delay set in machine data MD 65.
Fixed temperature 64
Default value Lower input limit Upper input limit Units
0 0 170 °C
Active
at once
Input of fixed temperature. If a value higher than 0 is entered, then the motor is operated at the
specified fixed temperature value.
Note:
The motor temperature monitoring function set in machine data MD 63 is made inoperative if a
fixed temperature is specified.
Timer motor temperature alarm 65
Default value Lower input limit Upper input limit Units
240 0 600 s
Active
at once
Input of timer for the motor temperature alarm. A warning is output as soon as the monitor
responds; the drive is then tripped with an alarm message when the delay time set above has
expired.
Address DAC2 72
Default value Lower input limit Upper input limit Units
3048 0000 FFFF Hex
Active
at once
Note:
This machine data is not included in the machine data lists. The DACs are configured in the
