Detailed description
2.4 Electronic gearbox (EG)
Power-up conditions of EG
The EG may be powered up:
• at the current axis positions (EGON) or
• at the synchronized positions to be specified (EGONSYN)
• at synchronized positions to be specified with details of an approach mode (EGONSYNE)
Block change behavior
In the EG activation commands (EGON, EGONSYN, EGONSYNE), it can be specified for
which condition (with respect to synchronism) the next block of the parts program is to be
processed. Options:
• NOC: no conditions
• FINE: Sum of the difference between the setpoint and actual positions of all axes less
• COARSE: Sum of the difference between the setpoint and actual positions of all axes
• IPOSTOP: When the specified end positions of the axes is reached
2.4.2 Definition of an EG axis group
Note
The following definition commands and switch instructions of the electronic gearbox must all
be contained in only one block of a parts program.
All commands of the electronic gearbox result in a preprocessing stop, except for the
activation commands:
• EGON
• EGONSYN
• EGONSYNE
Definition and activation
The definition described below and activation are separate processes. An activation is not
possible unless it has been defined previously.
