Overview
The rectified mains voltage is smoothed by the DC-bus capacitors. The motor is fed from
the DC bus via the switchable semiconductor components. The power stage includes
several safety functions some of which can be parameterised:
ƒ
Overvoltage / undervoltage monitoring
ƒ
Overcurrent monitoring
ƒ
Power stage monitoring
The implementation of the safety functions requires some basic information on the motor
to be controlled. The objects designed for this, are described below:
The power stage can be activated in different ways:
ƒ
Power stage activation via the CAN bus (state machine)
ƒ
Power stage activation via the »fluxx« software
ƒ
Power stage activation via the digital input (start/stop)
