Dual direction selection, and 10bit priority selection by control word.
When Control Input mode (H11) = 6 the control word is enabled. The control word replicates and extends the behaviour of the reference select bits,
Reference Select Bit 0 Input (G32) to Reference Select Bit 6 Input (G38), and the direction bit inputs, Direction Input 1 CCW (G39) and Direction Input
2 CW (G40).
A watchdog is provided to verify that an elevator controller using the control word is still updating the speed and direction inputs. The user must write
1 to watchdog bit every <=500 ms to prevent the watch dog from stopping the elevator and causing a trip Trip 77 (Ctrl Watchdog).
The table below details the bits within the control word and their function:
When set to Off (0), the direction input operation is not inverted. For single direction input operation, if Direction Input 1 CCW (G39) = Off (0)
clockwise direction is selected, and if Direction Input 1 CCW (G39) = On (1) then counter clockwise direction is selected. For dual direction input
operation, if Direction Input 1 CCW (G39) = On (1) then counter clockwise direction is selected, and if Direction Input 2 CW (G40) = On (1) then
clockwise direction is selected.
When set to On (1), the direction input operation is inverted. For single direction input operation, if Direction Input 1 CCW (G39) = Off (0) counter
clockwise direction is selected, and if Direction Input 1 CCW (G39) = On (1) then clockwise direction is selected. For dual direction input operation, if
Direction Input 1 CCW (G39) = On (1) then clockwise direction is selected, and if Direction Input 2 CW (G40) = On (1) then counter clockwise
direction is selected.
Control Input mode (H11) selects dual or single direction input mode.
This sets the velocity threshold 1 switch threshold where:
Open loop
• If Profile speed (J39) is <= Velocity Threshold 1 (H13) then Velocity Threshold 1 Status Output (J42) On (1).
• If Profile speed (J39) is >= Velocity Threshold 1 (H13) then Velocity Threshold 1 Status Output (J43)
Off (0).
•I
f Actual Speed (J40) is <= Velocity Threshold 1 (H13) then Velocity Threshold 1 Status Output (J48) = On (1).
Bit Speed reference (creep speed by default) Priority
0 Selects V1. If a higher priority speed is selected it will override this speed selection.
10
(lowest)
1 Selects V2 speed reference. If a higher priority speed is selected it will override this speed selection. 9
2 Selects V3 speed reference. If a higher priority speed is selected it will override this speed selection. 8
3 Selects V4 speed reference. If a higher priority speed is selected it will override this speed selection. 7
4 Selects V5 speed reference. If a higher priority speed is selected it will override this speed selection. 6
5 Selects V6 speed reference. If a higher priority speed is selected it will override this speed selection. 5
6 Selects V7 speed reference. If a higher priority speed is selected it will override this speed selection. 4
7 Selects V8 speed reference. If a higher priority speed is selected it will override this speed selection. 3
8 Selects V9 speed reference. If a higher priority speed is selected it will override this speed selection. 2
9 Selects V10 speed reference. If a higher priority speed is selected it will override this speed selection.

Watchdog bit. This must be set to 1 at least every 500 ms or less. Failure to do this will result in a Trip 77 (Ctrl Watchdog). If a
travel is in progress the elevator will perform a controlled stop and then trip.
