2.1.1.1 Power element
The servo amplifier's power element has the following features:
} Connection to earthed three-phase supplies, rated voltage range 208V – 480V
} TN network and TT network with earthed star point, max. 42 kA symmetrical rated cur-
rent, connection to other networks only with isolating transformer
} B6 rectifier bridge integrated directly on the three-phase, earthed network, mains filter
and start-up circuit
} Fuse protection (e.g. blow-out fuse) through user
} All shield connections directly on the servo amplifier
} Max. intermediate circuit voltage in generator mode: 260 – 900VDC, can be connected
in parallel
} Brake chopper, brake power distributed over several amplifiers on the same intermedi-
ate circuit
} Optionally, an energy store can be connected to the intermediate circuit (see Energy
store PMCenergy SD [ 115]).
} No internal brake resistor, external brake resistor available if required.
} Inverted rectifier with isolated current measurement and IGBT transistors
} Connection of synchronous servo motors, linear motors, asynchronous motors
} Integrated noise suppression filters in accordance with EN61800-3
