l
BB6 rectifier bridge, off 3-phase earthed (grounded) supply, integral inrush circuit
l
Fusing (e.g. fusible cutout) provided by the user
l
All shielding connections directly on the amplifier
l
Output stage: IGBT- module with isolated current measurement
l
Brake circuit: with dynamic distribution of the brake power between several
amplifiers on the same DC bus link circuit, external brake resistor
l
DC bus link voltage 260 ... 900 VDC, can be switched in parallel
l
Interference suppression filter for the 24V aux. supply (to category C2) is integrated
External interference suppression filter for the supply input (to category C2)
required. External mains choke required.
Integrated safety
l
Safe electrical separation between the power input / motor connections and the signal elec-
tronics, provided by appropriate insulation/creepage distances and complete electrical isola-
tion
l
Soft-start, overvoltage recognition, short-circuit protection, phase-failure monitoring
l
Temperature monitoring of servo amplifier and motor
(when using our motors with our pre-assembled cables)
Auxiliary supply voltage 24VDC
l
Electrically isolated, internal fusing, from an external 24VDC psu, e.g. with isolating transfor-
