Closed-loop Logic Outputs C3
119
curr reg flt
(Current Regulator Fault)
The output is true when the actual current
measurement does not match commanded
current.
drv overload
(Drive Overload)
The output is true when the drive has exceeded
the drive overload curve.
encoder flt
(Encoder Fault)
The output is true when the drive is declaring an
encoder fault
fan alarm
(Fan Alarm)
The output is true when the fan on the drive is
not functioning.
fault
(Fault)
The output is true when a fault is declared by the
drive.
flux confirm
(Motor Flux Confirmation)
The output is true when the drive has confirmed
there is enough flux to issue a speed regulator
release (the drive’s estimate of flux must reach
75% of reference).
fuse fault
(Fuse Fault)
The output is true when the DC bus fuse has
blown.
ground fault
(Ground Fault)
The output is true when the sum of all phase
current exceeds 50% of rated current of the
drive.
in low gain
(In Low Gain)
The output is true when the speed regulator is in
“low gain” mode.
motor trq lim
(Motor Torque Limit)
The output is true when the torque limit has
been reached while the drive is in the motoring
mode. The motoring mode is defined as the
drive delivering energy to the motor.
mtr overload
(Motor Overload)
The output is true when the motor has exceeded
the user defined motor overload curve.
no function
(No Function)
This setting indicates that the terminal or relay
will not change state for any operating condition;
i.e. the output signal will be constantly false.
not alarm
(Not Alarm)
The output is true when an alarm is NOT
present.
over curr flt
(Motor overload current fault)
The output is true when the phase current has
exceeded 300% of rated current.
overspeed flt
(Overspeed Fault)
The output is true when the motor has gone
beyond the user defined percentage contract
speed for a specified amount of time.
overtemp flt
(Heatsink Over Temperature Fault)
The output is true when the drive’s heatsink has
exceeded 90
°
C (194
°
F).
overvolt flt
(Over Voltage Fault)
The output is true when the DC bus voltage
exceeds 850VDC for a 460V class drive or
425VDC for a 230V class drive.
ovrtemp alarm
(Drive Over Temperature Alarm)
The output is true when the drive’s heatsink
temperature has exceeded 80
°
C (176
°
F).
phase fault
(Phase Loss)
The output is true when the drive senses an
open motor phase.
ramp down ena
(Ramp Down Enable)
The output is true after a torque ramp down stop
has been initiated by either a logic input, the
serial channel, or internally by the drive. When
this output is true the torque is being ramped to
zero.
ready to run
(Ready to Run)
The output is true when the drive’s software has
been initialized and no faults are present.
regen trq lim
(Regeneration Torque Limit)
The output is true when the torque limit has
been reached while the drive is in the
regenerative mode. The regenerative mode is
defined as when the motor is returning energy to
the drive. When the drive is in regenerative
mode, the energy is dissipated via the dynamic
brake circuitry (internal brake IGBT and external
brake resistor).
run commanded
(Run Commanded)
The output is true when the drive is being
commanded to run.
