2.1 2.1 Axis-specific referencing
In axis-specific reference point approach, reference point approach must be initiated
individually for each machine axis that is to be referenced.
Selection of mode and machine function
Before starting reference point approach of the machine axes, you must first place the
relevant mode group in JOG or MDA mode:
DB11, ... DBB0.2 (JOG mode)
DB11, ... DBB0.1 (MDA mode)
Then, select machine function REF (reference point approach):
DB11, ... DBB1.2 (REF machine function)
Start reference point approach
In axis-specific reference point approach, each machine axis must be started individually.
Reference point approach is started with the axis-specific traversing keys:
DB31, ... DBB4.6 (minus traversing key)
DB31, ... DBB4.7 (plus traversing key)
Direction enable
To avoid operator errors, direction enable must be parameterized.
The direction enable specifies which traversing key starts the reference point approach:
MD34010 $MA_REFP_CAM_DIR_IS_MINUS (approach reference point in minus direction)
Jog mode
The following machine data element can be used to specify whether reference point
approach is completed when the direction key is pressed once or whether the operator is
required to keep the direction key pressed (jogging) for safety reasons:
MD11300 $MN_JOG_INC_MODE_LEVELTRIGGRD (INC and REF in jog mode)
