I.5.2 Digital servo amplifier concept

Operation and parameter setting

Via the parallel interface of a PC using the special operator software BS7200

Power section

Mains supply : B6 bridge rectifier with current inrush limiter, 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.

Digital functions

— Current and speed control

— Processing of the 14-bit resolver evaluation

— Position output (incremental or 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 a 3-phase 400V mains without transformer,

mains filter series 3EFxx

— 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

— For a short time, at the instant of switching on, the power supply has to

provide twice the rated current, so that the power sections can start up the

servo amplifiers which are connected.

Intrinsic safety — Electrically safe isolation to VDE 0160 (proposed 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.1)

— Motor choke (see chapter I.11)
