INVERTER ERROR CODES
FasTrax - Inverter Error Codes
Trip Code Condition Possible Cause
tr UU DC bus under voltage Low AC supply voltage, check power source.
Low DC voltage when supplied by an external DC power supply.
tr OV DC bus over voltage The DC bus (Pr. 84) has exceeded 800V-460V or 400V-230VAC, check the following:
If DC bus climbs while door is not running, disconnect CE filter with power off.
If fault is intermittent when door is not running try to set Automatic reset of faults.
(PR. 73 = 10.34, PR. 74=10.36, PR. 63 = 3, PR 64 = on)
If fault is while door is closing add breaking resistor, see Control Box Explosion for a
list of parts. Deceleration rate set too fast for the inertia of the machine.
Mechanical load driving the motor.
tr It.br I

C on braking resistor Check door closing speed. If fault is while door is closing, add breaking resistor, see
Control Box Explosion for parts breakdown. See tr OV for more troubleshooting.
tr It. AC I
2
C on drive output Check that radial spacing and that they are square, or sideframe spacing.
Motor wiring, check for loose connections or shorts.
Make sure door cannot move if brake is engaged.
tr OI.AC Drive output instantaneous Door is mechanical binding or jammed.
over current Check that radial spacing and that they are square, or sideframe spacing.
Motor wiring, check for loose connections or shorts.
Make sure door cannot move if brake is engaged. Disconnect CE filter with power off.
Insufficient ramp times. Phase to phase or phase to ground short circuit on the drives
output. Drive requires autotuning to the motor.
Motor or motor connections changed, re-auto tune drive to motor
MUST wait 10 seconds to reset after trip occurs
Ol.br Braking resistor Excessive braking current in braking resistor
instantaneous over current Braking resistor value too small. MUST wait 10 seconds to reset after trip occurs
O.SPd Over speed Excessive motor speed (typically caused by mechanical load driving the motor)
tunE Auto tune stopped before complete Run command removed before autotune complete
It.br I
2
-t on braking resistor Excessive braking resistor energy
It.AC I
2
-t on drive output current Excessive mechanical load. Drive requires re-autotuning to motor.
High impedance phase to phase or phase to ground short circuit at drive output.
O.ht1 IGBT over heat based on Overheat software thermal model
drives thermal model
O.ht2 Over heat based on drives heatsink Heatsink temperature exceeds allowable maximum
th Motor thermistor trip Excessive motor temperature
O.Ld1 User +24V or digital output overload Excessive load or short circuit on +24V output
The Enable/Reset terminal will not reset an O.Ld1 trip. Use the Stop/Reset key.
OUL.d I x t overload Reduce motor current
hot Heatsink/IGBT temp is high Reduce ambient temperature or reduce motor current
br.rS Braking resistor overload See Advanced user guide
EEF Internal drive EEPROM failure Possible loss of parameter values
PH Input phase imbalance or One of the input phases has become disconnected from the drive
input phase loss
rS Failure to measure motors Motor too small for drive
stator resistance Motor cable disconnected during measurement
O.cL Overload on current loop input Input current exceeds 25mA
tr HF ## Hardware Fault The drive has detected a hardware problem, verify wiring is correct. This cannot be
fixed in the field, replace the drive.
HF 05 trip No signal from DSP at start up
HF 06 trip Unexpected Interrupt
HF 07 trip Watchdog failure
HF 08 trip Interrupt crash (code overrun)
HF 11 trip Access to the EEPROM failed
HF 20 trip Power stage - code error
HF 21 trip Power stage - unrecognized frame size
HF 22 trip Ol failure at power up
HF 25 trip DSP Communications failure
HF 26 trip Soft start relay failed to close, or soft start monitor failed or braking IGBT short circuit at power up
HF 27 trip Power stage thermistor fault
HF 28 trip DSp software overrun
HF xx trip HF 1-4, 9-10,12-19,23,24,29,30 Are not used
