Configuring the "Electronic Gearbox" TA

The technology application Electronic Gearbox is used in the following application range:
Slitters
•
Calender drives
•
Line drives
•
Transport belts
•
Vibrators
•
Roller plants
•
Stretching machines
•
Wire drawing systems
•
The "Electronic Gearbox" technology application allows a synchronism with adjustable
stretching ratio to be realised between the drives.
The conversion ratio is freely adjustable. The conversion ratio is specified in the form of a
•
fraction (numerator/denominator).
The master value selection can be performed using various interfaces:
•
Virtual master
•
System bus
•
Interface application feedback B
•
The electronic gearbox is set up using the following functions:
4Virtual master

The technology application can also be used for the status display and error message, or to
reset an error.
The technology application "Electronic Gearbox" only supports "modulo" axes. This means:
The master axis must be a "modulo" axis.
•
The slave axis must be a "modulo" axis.
•
Setting of the control mode
The control mode of the slave axis is configured by setting the parameter Default control
mode to "Position control motor encoder [0]"; otherwise, the axis will drift at standstill.
