B6 bridge rectifier with current inrush limiter, directly off
the 3-phase 400V mains
IGBT-module with electrically isolated current measurement
With electronic monitoring and internal ballast resistor.
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
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
— Electrically isolated, from an external 24V DC- power supply
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.
— 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)
— Mains filter (see chapter V.1)
— Motor choke (see chapter I.11)
