REVERSE
DISABLE
(P.015). The choices are:
ON
- Prevents the speed reference from going below zero (prohibits the drive
from operating in the opposite direction).
OFF
- (Default) Allows the speed reference to go below zero (allows the drive
to operate in the opposite direction)
.
If the speed reference is an analog signal, there may be an injection of a ripple on the
reference input. This may cause unwanted changes at the output of the
S
-
CURVE
block.
LINE
SPEED
HYSTERESIS
(P.136) sets a minimum signal change threshold below
which the input to the
S
-
CURVE
block will not change. This also smoothes the line
speed reference so that the
S
-
CURVE
block calculates the reference rate that is used by
inertia compensation.
