choices continued
flux confirm
(Motor Flux Confirmation) The output is true when the drive has confirmed there is enough motor field
current (flux) to issue a speed regulator release. Threshold is set by measured motor field current being
greater than that set at Motor parameter A6, Flux Confirm Level.
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” or response 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 faults (No Faults) No faults are currently present on the drive.
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.
ntsd active (Normal Terminal Stopping Device Active) The output is true when the drive is in NTSD mode.
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 95C
(203F).
overvolt flt (Over Voltage Fault) The output is true when the DC bus voltage exceeds 825VDC.
ovrtemp alarm
(Over Temperature Alarm) The output is true when the drive’s heatsink temperature has exceeded 85C
(185F).
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 2 start
(Ready to Start) The output is true when the drive’s software has been initialized, no faults are present and
the drive is
not boosting.
ready to run
(Ready to Run) The output is true when the drive’s software has been initialized, no faults are present and
the drive is boosting.
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).
Safe-off
Provides feedback to the car controller of the status of the Safe Off Input, and therefore the status of the
IGBTs (Enabled or Disabled). Used to determine if the drive has been correctly set for the “Safe Off”
function, and provide similar feedback to that of a contactor auxiliary. Can be configured to any free output.
This Output will be HIGH when the drive’s IGBTs are disabled by the Safe Off circuitry, and LOW when the
drive’s IGBT are enabled by the Safe Off circuitry.
The status of this output can be monitored in the D1 menu under Logic Outputs as a 1 or 0 as with any
other output.
run commanded (Run Commanded) The output is true when the drive is being commanded to run.
run confirm
(Run Command Confirm) The output is true after the software has initialized, no faults are present, the
drive has been commanded to run, the contactor has closed and the IGBTs are firing.
speed dev
(Speed Deviation) The output is true when the speed feedback is failing to properly track the speed
reference. The speed deviation needs to be above a user defined level. (Speed Dev. = reference -
feedback)
speed dev low
(Speed Deviation Low Level) The output is true when the speed feedback is properly tracking the speed
reference. The speed deviation needs to be within a user-defined range for a user-defined period of time.
(Speed Dev. = reference - feedback)
speed ref rls (Speed Reference Release) The output is true when the flux is confirmed and drive is NOT in DC injection.
speed reg rls
(Speed Regulator Release) The output is true when the flux is confirmed at 75% and brake is commanded
to be picked (if used)
undervolt flt
(Low Voltage Fault) The output is true when the DC bus voltage drops below the user specified percent of
the input line-to-line voltage.
up to speed (Up to Speed) The output is true when the motor speed is above the user specified speed
uv alarm
(Under Voltage Alarm) The output is true when the DC bus voltage drops below the user specified percent
of the input line-to-line voltage.
zero speed
(Zero Speed) The output is true when the motor speed is below the user specified speed for the user
specified time.
