15.4
Reference point appraoch from part program (G74)
Referencing of machine axes can be activated for the first time or repeated from the part program
Referencing must be repeated, for example, after:
• converting the actual value of the machine axis:
PRESETON
function
• Machine axis is parked:
DB31, ... DBX1.5 (position measuring system 1) = 0
DB31, ... DBX1.6 (position measuring system 2) = 0
• DB31, ... DBX2.1 (servo enable) = 0
• Exceeding the encoder limit frequency of the position measuring system
Programming
Syntax
G74
Machine axis
{
Machine axis
}
Function
Machine axes can be referenced from a part program with part program instruction
G74
Parameter:
Machine axes
The name of the machine axis must be specified. The machine axis must be a channel axis of the channel in
which the part program is processed.
Effective:
G74
is non-modal.
Special features
G74
must be programmed in a separate part program block.
Reset response
Mode group reset or channel reset aborts the reference point approach for all programmed machine axes:
DB11, ... DBX0.7 (mode group reset)
DB21, ... DBX7.7 (channel reset)
All machine axes for which the reference point approach is not yet successfully completed when the action is
cancelled remain in status "Not referenced":
DB31, ... DBX60.4 (referenced / synchronized 1)
DB31, ... DBX60.5 (referenced / synchronized 2)
