such that the elevator will remain stationary till the speed signal is given. It is intended to be used with elevator controllers that support fast starting

where the signal to close the elevator car door is routed to Fast Start Enable (H20) via a digital input, such that the following actions will happen

during door closing:

•

The motor contactors are closed

•

The motor is magnetized (IM) / Fluxed (PM)

•

The brake is released

The speed selection should only be applied when the door is closed.

If the elevator controller handles the control of the motor contactors, Fast Start Enable (H20) must be set to On (1) before the motor contactors are

closed. This is to ensure that the elevator drive enable signal via auxiliary contacts on the motor contactors is received after the Fast disable signal.

If the elevator drive handles the control of the motor contactors via Motor Contactor Control Output (B31) then setting Fast Start Enable (H20) = On

(1) will begin the starting sequence, and request the motor contactors to close.

If the speed is not applied for 5 s after the load measurement state is reached, Elevator Software State (J03) = 5 then the fast enable will be aborted.

When set >0 and Fast Start Enable (H20) = On (1), this determines the maximum distance in mm which can be moved during a fast start. If the

distance is exceeded then a Trip 69 (Fast start err) is generated, applying the brake and preventing further movement.

When set = 0, or when fast Fast Start Enable (H20) = Off (0), Trip 69 (Fast start err) is disabled.

When set to Off (0), short floor landing is disabled.

When set to On (1), short floor landing is enabled.

Short floor landing has been created to allow operation with a short floor distance which is lower than the braking distance from the normal floor

selected speed. In this case peak curve operation cannot be used where the short floor distance is less than 0.7 m for example. For these short floor

distances, the short floor landing mode is available with real distance control until the creep speed defined by Creep Speed Select (G52) is reached in

Creep to floor mode.

The short floor landing distance is defined by Short Floor Landing Distance (G30) in mm, which is the distance from the current floor position to the

floor / door zone.

The maximum operating speed is derived from both the short floor distance and the profile settings i.e. it is in position profile with speed target mode.

Once the short floor landing distance has been reached the elevator will complete the travel operating at the creep speed defined by Creep Speed

Select (G52) to a stop.

Short floor landing is selected using a digital input from the elevator controller routed to Short Floor Landing Enable (H22) for operation with short floor

less then 0.7 m for example. The control signals for the creep speed defined by Creep Speed Select (G52) and short floor landing enable must be

applied simultaneously. The maximum operating speed is internally calculated so that the creep speed defined by Creep Speed Select (G52) is

reached after the short floor landing distance, Short Floor Landing Distance (G30), and when the floor (door) zone is reached.
