2 current ratings (40 A, 70 A)
wide range of rated voltage (3x208V
shield connection directly at the servo amplifier
two analog setpoint inputs
integrated CANopen (default 500 kBaud), for integration into CANbus systems and for
setting parameters for several amplifiers via the PC-interface of one amplifier
integrated RS232, electrically isolated, integrated pulse-direction interface

TN-system, TT-system with earthed (grounded) neutral point, not more than 5000 rms sym-
metrical amperes, 480VAC maximum; when protected by fuses type Fusetron FRS-R-80
(Class RK5), manufactured by Bussman, or equivalent 480VAC min
Connection to other mains supply networks only with insulating transformer ð p. 16
BB6 rectifier bridge, off 3-phase earthed (grounded) supply, integral inrush circuit
Fusing (e.g. fusible cutout) provided by the user
All shielding connections directly on the amplifier
Output stage: IGBT- module with isolated current measurement
Regen circuit: with dynamic distribution of the regen power between several
amplifiers on the same DC bus link circuit, external regen resistor
DC bus link voltage 260 — 900 VDC, can be switched in parallel
Interference suppression filter for the 24V aux. supply (to category C2) is integrated
Safe electrical separation to EN 50178 between the power input / motor connections and the
signal electronics, provided by appropriate insulation/creepage distances and complete elec-
trical isolation
Soft-start, overvoltage recognition, short-circuit protection, phase-failure monitoring
Temperature monitoring of servo amplifier and motor
(when using our motors with our pre-assembled cables)
