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
store PMCenergy SD [
} 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
