A Proximity Sensor For Speed Measurement - Danfoss Vacon OPTEA Operating Manual

VACON® NXP Advanced Safety Options
Operating Guide
When you use the safety-aware Multipurpose drive application, the SS1 function is realized by the drive application when the SS1
function is requested from the Advanced safety option board. The ramp definitions for the controlled ramp are taken from drive
ramp 1.
The SLS speed limit is realized by the drive application when the SLS function is requested from the Advanced safety option board.
The speed limit is taken from the Advanced safety option board. The drive application limits the speed to 95% of the parameterized
limit. Ramping below the speed limit is realized using drive ramp 1.

13.9 A Proximity Sensor for Speed Measurement

This is a configuration for one proximity sensor with the Advanced safety option board OPTBL. No safety functions are included in
this example. A proximity sensor with 16 pulses per rotation and an ACTIVE-INACTIVE signal duty cycle of 1:1 is used.
