3 Technical data
3.1 Features
Controller and system features
( Control electronics and system software are the same for 48XX/49XX
( Digital speed feedback with resolver or incremental encoder
( Torque control with superimposed speed monitoring for winding drives
( Phase control for drift-free positioning
( Digital frequency coupling as setpoint bar or setpoint cascade for
- phase synchronisation
- speed-synchronous operation
- synchronous speed ratio
( Increase of the max. armature voltage to 115 % ôV
mains
by changing from 4Q
to 2Q operation (with 49XX)
( Speed accuracy better than 0.5‰ at 100% changing load with resolver
feedback or incremental encoder
( Speed setting range 1:1000 at constant load with resolver feedback or
incremental encoder
( Current setting range 1:300 by means of pulse current adaptation and
bridge modulation
( Speed-dependent armature current limitation
( Adjustable max. armature current from 112,5 % to 180 % rated current
(depending on the size)
( Freely connectable process controller, e.g. for dancer position control or
tension control
( Integrated field current control for large speed setting range
( 4 customer-specific parameter sets can be saved and changed via digital
input terminals
Operation
( On-line changes of control parameters
( Parameter setting and diagnosis via
- keypad with two-line LCD in German, Englisch and French
- serial interface and PC
- fieldbus module (as option): PROFIBUS, InterBus
