SERVOSTAR 601...620 Installation Manual
With our user-friendly software for setup through the serial interface of a PC
Direct operation by means of two keys on the servo amplifier and a 3-character LED display
for status display in case there is no PC available
Fully programmable via RS232 interface
Power supply: B6 rectifier bridge, directly off 3-phase earthed (grounded)
supply system, integral power input filter and inrush circuit
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-link circuit. Internal regen resistor as
standard, external regen resistors if required
DC-link voltage 260 — 900 VDC, can be switched in parallel
Digital current controller (space vector pulse-width modulation, 62.5 µs)
Freely programmable digital speed controller (65µs or 250 µs)
Integral position controller with adaptation possibilities for customer needs (250 µs)
Pulse direction interface integrated for connection of a servomotor to a stepping motor
control
Evaluation of the resolver signals and sine-cosine signals of a high-resolution encoder
Encoder simulation (incremental or SSI)
Adjustable setpoint ramps
2 analog monitor outputs
4 programmable digital inputs (normally, two are defined as limit-switch inputs)
2 programmable digital outputs
Freely programmable combinations of all digital signals
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)
