Slide parameters (continued)
211, 261, ... Position of probe or optical measuring
system
To define the position of the probe, enter its external
coordinates.
To define the position of the optical measuring
system, enter the position of the cross hairs (+X/+Z).
Reference: Machine zero point
■ Position of probe/optical measuring system +X
■ Position of probe –X
■ Position of probe/optical measuring system +Z
■ Position of probe –Z
511..542, 561..592, ... Description of tool holders
Positions of the tool holders relative to the tool-carrier
reference point.
■ Distance to carrier reference point X/Z/Y: Distance between
reference point of tool carrier and reference point of tool holder.
■ Compensation X/Z/Y: Compensation value for the distance between
reference point of tool carrier and reference point of tool holder.
Spindle parameters
804, 854, ... Protection-zone monitoring for spindle – not used at present
805, 855, ... General spindle parameters
■ Zero point shift (M19): Defines the distance between the reference
point of the spindle and the reference point of the encoder. After
receiving the reference pulse from the encoder, the value determined is
transferred.
■ Number of revolutions for backing off: Number of spindle
revolutions after the spindle has stopped in Automatic mode. (When
using low spindle speeds, additional spindle revolutions are necessary
to relieve the tool.)
806, 856, ... Tolerance values, spindles
■ Speed tolerance [%]: The system proceeds from a G0 block to a G1
block as soon as the status ”Speed reached” is attained. When the
speed lies within the tolerance range, the status is attained. The
tolerance value refers to the nominal speed.
■ Position window, position [°]: After the spindle has stopped at a
defined position (M19), the system proceeds to the next block as soon
as the status ”Position reached” is attained. When the difference
between nominal and actual value lies within the tolerance range, the
status is attained. The tolerance value refers to the nominal speed.
■ Speed tolerance, synchronization [rpm]: Criterion for status
”Synchronization reached.”
■ Position tolerance, synchronization [°]: Criterion for status
”Synchronization reached.”
The parameter settings for the slave spindle are the decisive ones.
