Figure 7-24 Floor sensor correction logic diagram
Floor sensor correction utilizes a feature of digital input 5, which bypasses the normal input logic resulting in a fast response to a change in the input
signal, such that when the sensor is activated the position is sampled in <1 µs. When digital input 5 is used for floor sensor correction, it is
recommended that the input is not used for any other purpose and Digital Input 5 Destination (F22) should be set to a value of 'A00'. It is possible to
specify whether the positive or negative edge of the floor sensor correction signal is detected using Floor Sensor Correction Edge Detection (H25).
Figure 7-25 Floor sensor correction modes
7.21.1 Floor sensor correction, direct to floor, on detection of signal via digital input 5
When the floor sensor correction signal is detected, travel within Floor Sensor Correction Target Distance (G31) is position controlled, modifying the
profile (deceleration and jerk rates) as required.
Once the floor sensor correction signal becomes active, the remaining controlled distance to the floor level is displayed in Remaining Floor Sensor
Correction Distance (J47). The speed at the point floor sensor became active is displayed in Speed At Floor Sensor Correction Active (J46).
Figure 7-26 Floor sensor correction, direct to floor, on detection of signal via digital input 5
It should be noted that the floor sensor correction signal should be activated instantaneously at a position which is Floor Sensor Correction Target
Distance (G31) away from the floor sensor in mm. If the stop distance is too low or the floor sensor signal was given at too high a speed (see Speed
At Floor Sensor Correction Active (J46)) the elevator may not be able to stop smoothly and therefore a hard stop will be implemented.

Profile Floor Sensor Correction Mode
Direct to floor
Floor sensor correction is enabled via detection of the floor sensor correction signal connected to digital input 5. Travel within
Floor Sensor Correction Target Distance (G31) is position controlled, modifying the profile as required.
Creep to floor
Floor sensor correction is enabled via detection of the floor sensor correction signal connected to digital input 5. Travel within
Floor Sensor Correction Target Distance (G31) is position controlled, modifying the profile (deceleration and jerk rates) as
required.
Floor sensor correction is enabled via de-selection of the creep speed reference. Travel within Floor Sensor Correction Target
Distance (G31) is position controlled, modifying the profile (deceleration and jerk rates) as required.
