Module parameters
Name Description
Resolution Determines the resolution of the speed value on the PROFINET
interface. 1 digit can correspond to 0.1 mm/s, 1 mm/s,
10 mm/s or 100 mm/s.
Value range
• 0.1 mm/s
• 1 mm/s
• 10 mm/s
• 100 mm/s
• free Speed Resolution [µm/s]
Default value
• 1 mm/s
Free speed
resolution
Determines the resolution of the speed value on the PROFINET
interface if the “free Speed Resolution [µm/s]” value has been
selected in the “Resolution” parameter.
Value range
• 1 ... 100,000 µm/s
Default value
• 1,000 µm/s
10.3.4 Module 4: “Distance/i2w, Speed/i2w”
Type Input module, 4 words, consistent
Description This module reads both the current distance and the currently ascertained
speedinaccordancewiththeselectedresolutionandoset.
