Drive Running (RUN)
The logic output is at state 1 if the motor is being fed by the drive
controller (current present) or if a run command is generated with a zero
speed reference.
Frequency Threshold Attained (FtA)
The logic output is at state 1 if the motor frequency is greater than or
equal to the frequency threshold set by the Ftd parameter in the
2—Adjust menu.
Frequency Reference Attained (SrA)
The logic output is at state 1 if the motor frequency is equal to the speed
reference value.
High Speed Attained (FLA)
The logic output is at state 1 if the motor frequency is equal to the high
speed value (HSP).
Current Threshold Attained (CtA)
The logic output is at state 1 if the motor current meets or exceeds the
current threshold set by the Ctd parameter in the 2—Adjust menu.
Thermal State Attained (tSA)
The logic output is at state 1 if the motor thermal state ismeets or exceeds
the thermal state set by the ttd parameter in the 2—Adjust menu.
Loss of 4–20 mA signal (APL)
The logic output is at state 1 if the signal on the 4–20 mA speed reference
input is less than 2 mA.
Brake Logic Command (bLC) (This parameter is only assignable to R2)
Brake Logic Command allows management of a mechanical brake by the
drive controller. Figure 19 on page 70 shows a timing diagram for Brake
Logic.
