Off-delays
Based on the set of off-delay parameters, the nominal, medium, speed2 and speed3
references, that is, the traveling speeds can be used for a prolonged period, despite
change in the status of the speed reference selection bits. The off-delay parameter
set contains adjustable speed limit and delay periods for each traveling speed
reference. The off-delays are used only when the elevator speed is below the set
speed limit.
The figure below illustrates the normal running sequence of a elevator traveling from
one floor to another and the use of off-delay for the nominal speed:

Parameters Additional information
80.01 NOMINAL SPEED Defines the nominal speed reference used in the normal travel mode.
80.06 SPEED REF SEL1 Selects the source for speed reference selection bit 1.
80.07 SPEED REF SEL2 Selects the source for speed reference selection bit 2.
80.08 SPEED REF SEL3 Selects the source for speed reference selection bit 3.
80.10 SPEED1 A factory-set zero speed reference, which can be used for stopping the
elevator in the normal travel mode.
80.11 LEVELING SPEED Defines the speed reference to be used during leveling.
80.12 RELVL SPEED SEL Selects the source of the releveling speed reference.
80.13 RELEVELING SPEED Defines the speed reference to be used during releveling when selected
as the source of parameter 80.12.
80.14 MEDIUM SPEED Defines an additional speed reference which can be used instead of the
nominal speed based on the floor distance.
80.15 INSPECTION SPEED Defines the speed reference used in the inspection mode. Can also be
used in the normal travel mode if the inspection mode is not in use.
