Figure 7-6 Stop signal for Direct to floor
Direct to floor operation utilizes a feature of digital input 4, 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 signal is sampled in <1 µs. When digital input 4 is used for the Direct to floor slowing signal, it is
recommended that the input is not used for any other purpose and Digital Input 4 Destination (F21) 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 Direct To Floor Edge Detection (H10).

7.8 Creep to floor / Direct to floor - Start
For geared and gearless Elevator applications operating in Creep to floor mode / Direct to floor mode, the start performance can be optimized using
the following procedure. For open loop operation only the start optimizer is available.
Table 7-15 Start set-up control
Feature Details
Speed control loop gains
For Closed loop operation the Start Speed Loop P Gain (I01) and Start Speed Loop I Gain (I02) gains can be used for
optimization
Start lock
A start lock position control is available for Closed loop operation and used in addition to the start speed loop gains. This
control is mainly used in gearless applications where high start speed loop gains may not possible.
Start optimizer
The start optimizer is available for both Open and Closed loop operation with either geared or gearless Elevators. The
start optimizer is mainly used to overcome mechanical imperfections in the system.
