Gap control limit
Setting of trigger limit (S1) of Gap control.
To determine the value proceed as follows (Manual operating mode – Gap
environment):
 start the grinder observing the usual working conditions (grinding wheel and part
rotating, coolant on, etc).
 record the mean value of the background noise (RM0), with the wheel at rest
position (away from the workpiece).
 bring the wheel in proximity of the workpiece and record the mean noise value
(RM1) (without touching the workpiece).
In case of constant background noise ( programming) the value of the Gap
limit (S1) (absolute value) must be:
S1 = 0.75 x (RM1 - RM0) + RM0
In case of variable background noise ( programming) the value of the Gap
limit (S1) (incremental relative value) must be:
Gap control
trigger modality
Gap control limit
Delay on Gap control
