The FLEXELEMENT 1 HYSTERESIS setting defines the pickup–dropout relation of the element by specifying the width of the
hysteresis loop as a percentage of the pickup value as shown in the FlexElement direction, pickup, and hysteresis diagram.
The FLEXELEMENT 1 DT UNIT setting specifies the time unit for the setting FLEXELEMENT 1 dt. This setting is applicable only if
FLEXELEMENT 1 COMP MODE is set to “Delta”. The FLEXELEMENT 1 DT setting specifies duration of the time interval for the
rate of change mode of operation. This setting is applicable only if
FLEXELEMENT 1 COMP MODE is set to “Delta”.
This
FLEXELEMENT 1 PKP DELAY setting specifies the pickup delay of the element. The FLEXELEMENT 1 RST DELAY setting
specifies the reset delay of the element.
