Motor Module
The Motor Modules assigned to 1FW3 motors are dimensioned for a rated motor current I
N
.
If the full motor stall torque is required, then you must dimension the Motor Modules
according to the motor stall current (I
0
).
If the motor is temporarily operated at operating points above the S1 characteristic, you must
take into consideration the actual current demand of the motors and appropriately select the
Motor Modules.
Note
Configuration tool
The SIZER for SIEMENS Drives engineering tool supports you when dimensioning and
engineering the drive system (see Chapter "
SIZER configuration tool (Page 91)").
