9400 HighLine | Parameter setting & configuration
TAs for interconnection via electrical shaft
TA "Electronic gearbox"
12.2 TA "Electronic gearbox"
The technology application "Electronic gearbox" serves to implement a synchronism with
adjustable stretching ratio between the drives in the system.
r The ratio can be freely adjusted, the values are input in the form of a fraction
(numerator/denominator) with 32 bit resolution.
r 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).
r 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
r Virtual master with inching, handwheel and reduced speed.
r Master value conditioning (master shaft) with master value scaling, stretch factor and
reversal of rotation direction.
r Virtual clutch with emergency stop and basic speed
r Trimming function via profile generator.
r Master value conditioning (machine axis/tool) with setpoint scaling.
r Additional operating modes for activating the basic drive functions "Homing", "Manual
jog (inching)" and "Position override function".
r Support of the basic drive functions "Quick stop" and "Limiter".
r Following error monitoring.
r Optional control of a holding brake.
Note!
The electrical shaft can be implemented with a bus system as e.g. system bus
(CAN) or Ethernet Powerlink or via digital frequency transmission.
With regard to the configuration of the digital frequency extension module in
the controller, two variants of technology applications are available in the
»Engineer« application catalog.
• In the TA variant "Electronic gearbox" the configuration of a digital frequency
extension module is expected. Therefore, the TA can provide the function of
the electrical shaft either via digital frequency transmission and via a bus
system.
• In the TA variant "Electronic gearbox MotionBus" the configuration of a digital
frequency extension module is not included and corresponding interfaces are
not available in the TA. Thus the function of the electrical shaft with this TA
can only be provided via a bus system.
