7.21.2 Floor sensor correction, creep 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 7-27 Floor sensor correction, creep 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.
When the sensor input is triggered the elevator will come to a stop with Creep speed still selected. If Creep speed is deselected prior to the floor
sensor correction trigger point the final relative position may not match the distance specified in Floor Sensor Correction Target Distance (G31).
7.21.3 Floor sensor correction, creep to floor, on de-selection of creep speed
The floor sensor correction system is only armed when the creep speed is reached. The elevator controller must de-select Creep speed at the correct
position i.e. Floor Sensor Correction Target Distance (G31) mm from the target floor. Creep speed is maintained under position control during the
remaining distance to the target floor with profile parameters (deceleration and jerk) controlled to stop the elevator accurately at the target floor.
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 7-28 Floor sensor correction, creep to floor, on de-selection of creep speed
It should be noted that the Creep speed should be de-selected 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.
