regen trq lim
[44]
(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
[45]
(Run Commanded) The output is true when the drive is being commanded to run.
run confirm
[46]
(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.
Safe-Off Input
[47]
This output is high when the drives safe off input is not present and the drive is therefore
disabled by the safe off feature. This feature is enabled by the control card’s ‘Safe Off’ switch.
speed dev
[48]
(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
[49]
(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
[50]
(Speed Reference Release) The output is true when the flux is confirmed and drive is NOT in
DC injection.
spd ref rel2
[51]
(Speed Reference Release 2) The output is true when:
software initialized and no faults present
drive being commanded to run (contact confirm true, if used)
not in DC injection
SPEED COMMAND SRC(C1) parameter = multi-step
speed reg rls
[52]
(Speed Regulator Release) The output is true when the flux is confirmed at 75% and brake is
commanded to be picked (if used)
stltst active
[53]
(Stall Test Active) The output is true when the drive is declaring a Stall Test Fault. The Stall
Test Fault checks that motor current goes at or above a percentage (defined by STALL TEST
LVL(A1)) for defined amount of time (defined by STALL FAULT TIME(A1)). If the motor current
exceeds the defined parameters a STALL TEST FAULT will be declared.
Undervolt flt
[54]
(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
[55]
(Up to Speed) The output is true when the motor speed is above the user specified speed
uv alarm
[56]
(Low 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
[57]
(Zero Speed) The output is true when the motor speed is below the user specified speed for the
user specified time.
