Coding

This indicates deceleration distance in mm, which is derived from the Profile generator output position and the target stopping position or the creep
speed.
In Creep to floor, this indicates the distance used in the decelerating state, Elevator Software State (J03) = 9, which is the distance used to get from
the speed at the time the deceleration state was entered to the creep speed. If floor sensor correction is triggered during the deceleration state then
this shows the distance to a stop instead of the creep speed.
In Direct to floor, Elevator Control Mode (H19) = Direct To Floor (1), this indicates the distance used in the decelerating state, Elevator Software State
(J03) = 9, which is the distance used to get from the speed at the time the deceleration state was entered to a stop.
This is not available when an analog reference is selected, Control Input Mode (H11) = Analog Run Prmit or Analog 2 Dir (0 or 1).

Type
16 Bit Volatile
Display Format
Standard
Coding
RO, ND, NC, PT
This indicates the sampled profile deceleration distance in mm, for the selected speed, V1 Speed Reference (G01) to V10 Speed Reference (G10),
which is derived from the profile setup parameters in the Profile menu.
When only V1 Speed Reference (G01) is selected this shows the distance from the creep speed to zero speed. When V2 Speed Reference (G02) to
V10 Speed Reference (G10) is selected this shows the distance from the selected speed to V1 Speed Reference (G01).
In Direct to floor, Elevator Control Mode (H19) = Direct To Floor (1), this shows the distance from the selected speed, V1 Speed Reference (G01) to
V10 Speed Reference (G10) to zero speed.
This is not available when an analog reference is selected, Control Input mode (H11) = Analog Run Prmit or Analog 2 Dir (0 or 1).

Deceleration Distance Measured

Default
Type
16 Bit Volatile
Display Format
Standard
Coding
RO, ND, NC, PT
This indicates measured deceleration distance in mm, which is derived from the feedback position sampled when deceleration begins to when the
elevator motor stops or reaches the creep speed.
In Creep to floor, this indicates the distance used in the decelerating state, Elevator Software State (J03) = 9, which is the distance used to get from
the speed at the time the deceleration state was entered to the creep speed. If floor sensor correction is triggered during the deceleration state then
this shows the distance to a stop instead of the creep speed.
In Direct to floor, Elevator Control Mode (H19) = Direct To Floor (1), this indicates the distance used in the decelerating state, Elevator Software State
(J03) = 9, which is the distance used to get from the speed at the time the deceleration state was entered to a stop.
In RFC-A and RFC-S:
This is based on the actual encoder position feedback.
