Approach speed K

Resulting resolution d
d = (H/15) + 50 mm
Required resolution must be
calculated for the specified
height.
Safety clearance S
S = (1600 mm/s × T) + (1200 mm – 0.4
× H)
S may not be
≤
850 mm.
S is between the danger
zone and the furthest beam
of the sensor.
Example:
• ESPE response time = 10 ms
• ESPE resolution = 14 mm
• Machine over-travel time = 330 ms
• Reference height = 500 mm
S = 1600 mm/s × (0.33 s + 0.01 s) + 1200 mm – (0.4 × 500 mm)
S = 1544 mm
• Resultant resolution d = (500 mm/15) + 50 mm = 83.3 mm
