I.5.2 Digital servo-amplifier concept
Operation and parameter setting
Standard : Via the parallel interface of a PC using the
special operator software BS7200
Optional : By three-key operation directly on the servo-amplifier and
LCD-display, only for units without a CONNECT module
Power section
Mains supply : B6 bridge rectifier directly off the 3-phase 400V mains
Output stage : IGBT-module with electrically isolated current measurement
Ballast circuit : With electronic monitoring and internal ballast resistor.
External ballast resistor if required (please consult us about
the parameter setting of the servo-amplifier)
Digital functions
— Current and speed control
— Processing of the 14-bit resolver evaluation
— Position output (incremental or optional SSI) with analog setpoint input
— Communication with the various interface modules and positional control,
if an interface module is installed
Easy-to-use functions
adjustable setpoint ramps, limit-switch function, analog monitor outputs
I.5.3 Operation directly off a 400V mains
Power supply — Directly off an earthed 3-phase 400V mains without transformer,
mains filter series 3EFxx, mains choke (digifas™ 7133/7150)
— Fuse protection and phase-failure monitoring by the user
— Single-phase supply (only for power < 0.5kW) e.g. as a possibility
during commissioning or setting-up
Aux. supply — Electrically isolated, from an external 24V DC- power supply
25V DC with isolating transformer, mains filter 1EF06
Intrinsic safety — Electrically safe isolation to EN 50178 between the mains or motor
connection and the signal electronics through appropriate creepage
distances and full electrical isolation.
— Soft start, overvoltage detection, short-circuit protection
— Temperature monitoring of the servo-amplifier and motor
(when using motors from the 6SM series with our preassembled cables)
Additional interference suppression measures
— Mains filter (see chapter V.8)
— Mains choke (see chapter V.9)
