FLEXELEMENT 1 HYSTERESIS
— This 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.
FLEXELEMENT 1 dt UNIT
— Specifies the time unit for the setting
FLEXELEMENT 1 dt
. This setting is applicable only if
FLEXELEMENT 1 COMP MODE
is set to “Delta.”
FLEXELEMENT 1 dt
— 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.”
FLEXELEMENT 1 PKP DELAY
— Specifies the pickup delay of the element.
FLEXELEMENT 1 RST DELAY
— Specifies the reset delay of the element.
