Table 5–93: ANALOG COMPARATOR STATUS
The analog level value is by default in a reset state, when the value meets the comparison (inside or outside the
comparison band) the "Analog Level X" signal will be activated if the analog value remains active the time set in the analog
delay setting. When the activation conditions are not met the "Analog Level X" value will go to the reset state.
An analog change must remain active at least 40 ms to be considered, plus the analog time setting. Besides the snapshot
event data will have a 20 ms accuracy.
5.5.12 FREQUENCY RATE OF CHANGE
F650 uses a defined signal as frequency reference. This signal is analyzed by DSP and time between two consecutive
zero-crossing is measured. Reference signal is set in Setpoint > System Setup > General Settings > Frequency
Reference.
The settings can be selected at Setpoint > Control Elements > Frequency rate of change
