Protective Elements
Name Description
INSQSP2STFaill Signal: Fail to transit from stop to start based on reported back
time
INSQSt2RunFail Signal: Fail to transit from start to run based on reported back time
LATBlock Signal: Long acceleration timer enforced
ColdStartSeq Signal: Motor cold start sequence flag
ForcedStart Signal: Motor being forced to start
TripPhaseReverse Signal: Relay tripped because of phase reverse detection
EmergOverrideDI Signal: Emergency override start blocking through digital input DI
EmergOverrideUI Signal: Emergency override start blocking through front panel
ABSActive Signal: Anti-backspin is active. For certain applications, such as
pumping a fluid up a pipe, the motor may be driven backward for a
period of time after it stops. The anti-backspin timer prevents
starting the motor while it is spinning in the reverse direction.
Blo-GOCStart Signal: Ground Instantaneous Overcurrent Start Delay. GOC
(Instantaneous Overcurrent) elements are blocked for the time
programmed under this parameter.
Blo-IOCStart Signal: Phase Instantaneous Overcurrent Start Delay. IOC
(Instantaneous Overcurrent) elements are blocked for the time
programmed under this parameter.
Blo-I<Start Signal: Underload Start Delay. Underload(Instantaneous
Overcurrent) elements are blocked for the time programmed under
this parameter.
Blo-JamStart Signal: JAM Start Delay. JAM(Instantaneous Overcurrent)
elements are blocked for the time programmed under this
parameter.
Blo-UnbalStart Signal: Motor start block current unbalance signal.
Blo-Generic1 Generic Start Delay. This value can be used to block any
protective element. 1
Blo-Generic2 Generic Start Delay. This value can be used to block any
protective element. 2
Blo-Generic3 Generic Start Delay. This value can be used to block any
protective element. 3
Blo-Generic4 Generic Start Delay. This value can be used to block any
protective element. 4
Blo-Generic5 Generic Start Delay. This value can be used to block any
protective element. 5
I_Transit Signal: Current transition signal
T_Transit Signal: Time transition signal
StartMotorCmd Signal: Start motor command
MotorStopBlo Signal: Motor stop block other protection functions
