1103
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).
1104
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).
1105
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.
1106
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
