In case slide of press machine can be stopped where you would like to, safety distance S
can be calculate by calculating formula 1.

Minimum required distance between the sensing area surface and the danger-
ous parts of the machine.

In case the intrusion direction is horizontal to the sensing area, Taken as 1,600 (mm/
sec.) for calculation. In case the intrusion direction is perpendicular to the sensing area,
Taken as 2,000 (mm/sec.) for calculation when the safety distance is 500mm/s or less
and taken as 1,600 (mm/sec.) for calculation when safety distance is 500mm/s or more.

Calculate based on table below in case not using interlock function (start-restart
interlock) of this device or safety controller in press machine.

In case using interlock function (start-restart interlock) of this device or safety con-
troller etc. in press machine, C equals 0.
In case the slide of press machine can not be stopped in your desire point, the safety
distance S can be calculated from formula 2.
