2 Brief description
The technology application "Electronic gearbox" serves to implement a synchronism with
adjustable stretching ratio between the drives in the system.
 The ratio can be freely adjusted, the values are input in the form of a fraction
(numerator/denominator) with 32 bit resolution.
 The master value can be specified either by a "Virtual master", or via a bus system or the
digital frequency extension module. It is selected from the Application parameter tab
via the Master value source list field (C03052).
 The master value transmission (high speed stability) is preset. The actual values can be
transmitted by the corresponding selection in the list fields Master value output
(C3054/1, C3054/2, C3197).
Functions
 Virtual master with inching, handwheel and reduced speed.
 Master value conditioning (master shaft) with master value scaling, stretch factor and
reversal of rotation direction.
 Virtual clutch with emergency stop and basic speed
 Trimming function via profile generator.
 Master value conditioning (machine axis/tool) with setpoint scaling.
 Additional operating modes for activating the basic drive functions "Homing", "Manual
jog (inching)" and "Position override function".
 Support of the basic drive functions "Quick stop" and "Limiter".
 Following error monitoring.
 Optional control of a holding brake.
