To modify the results of the LIMIT block using REVERSE DISABLE (P.015).
▲
Set 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.
