units
Suggested adjustment
ACCEL RATE 0
Acceleration rate limit
0.8
m/s
2
Reduce if the acceleration is
too aggressive.
Increase if the acceleration is
too gentle
DECEL RATE 0
Deceleration rate limit
0.8
m/s
2
Reduce if the deceleration is
too aggressive.
Increase if the deceleration is
too gentle
ACCEL JERK IN 0
Rate of increase of
acceleration, up to
ACCEL RATE, when
increasing elevator
speed
0.6
m/s
3
Reduce to give a softer
acceleration from standstill
into the acceleration segment
Increase to give a more
aggressive transition into the
acceleration segment
ACCEL JERK OUT 0
Rate of decrease of
acceleration to zero
when approaching
contract elevator speed
0.6
m/s
3
Reduce to give a softer
transition to commanded
speed from acceleration
segment
Increase to give a more
aggressive transition to
commanded speed from
acceleration segment
DECEL JERK IN 0
Rate of increase of
deceleration, up to
DECEL RATE, when
decreasing elevator
speed
0.6
m/s
3
Reduce to give a softer
transition to the deceleration
segment from commanded
speed into the deceleration
segment.
Increase to give a more
aggressive transition from
commanded speed into the
deceleration segment.
DECEL JERK OUT 0
Rate of decrease of
deceleration to zero
when slowing the
elevator to leveling
speed
0.6
m/s
3
Reduce to give a softer
transition to Leveling speed
and to stop from the
deceleration segment.
Increase to give a more
aggressive transition to
Leveling speed and to stop
from the deceleration
segment.
