09.95 7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
Motor rated current 1103
Default value Lower input limit Upper input limit Units
0.0 0.0 500.0 A
Active on
Power On
Input of rated current consumption (RMS value) in operation at rated torque and rated speed
as specified on the motor data sheet (non-Siemens motor) or by automatic parameterization
using machine data "Motor code number" (MD 1102).
Maximum motor current 1104
Default value Lower input limit Upper input limit Units
0.0 0.0 500.0 A
Active on
Power On
Input of maximum permissible motor current (RMS value) as specified on the motor data sheet
(non-Siemens motor) or by automatic parameterization using machine data "Motor code
number" (MD 1102). To ensure reliable monitoring and limitation, the setting in this machine
data should not be reduced (see also MD 1105).
Reduction of maximum motor current 1105
Default value Lower input limit Upper input limit Units
100 0 100 %
Active
at once
Input of reduction factor for the maximum permissible motor current. The maximum motor
current (MD 1104) is the reference value for the specified percentage.
Note:
This machine data is relevant for FDD drives only.
Power section code number 1106
Default value Lower input limit Upper input limit Units
0000 0000 FFFF Hex
Active on
Power On
When the power section order number (machine-readable product designation for Siemens
power sections) is input during initial start-up, it is converted to a code number as an MMC
function (the user need not enter a code number). The following power section data are
automatically transferred from an internal power section table through the input of the code
number:
• MD 1107: Transistor limit current, power section
• MD 1108: Thermal limit current, power section
• MD 1109: Limit current power section S6
• MD 1111: Rated current power section
