SIMODRIVE base line A Start-Up
3.2. Infeed module
General
SIMODRIVE base line A is connected to the power supply via the infeed
modules. The infeed module generates the DC voltage 600V from the
line supply. And the PWM DC link voltage is provided for the stator
windings in the motor. The resolver built-in the motor switches over the
current to appropriate phase.
The infeed module is designed with a permissible dynamic overloading
200% for a short time. The design of heatsink overtemperature and I

monitoring protect the power part from over heating.
