8 Diagnostics
* The Enable/Reset terminal will not reset an O.Ld1 trip. Use the Stop/Reset key.
** These trips cannot be reset for 10 seconds after they occur.
See the Commander SK Advanced User Guide for further information on possible causes of drive trips.
Table 8-1 DC bus voltages
* These are the absolute minimum DC voltages the drives can be supplied by.
** The drive will trip on OV if the DC Bus goes above the OV trip level.
Do not attempt to carry out internal repairs. Return a faulty
drive to the supplier for repair.
WARNING
Trip code Condition Possible cause
UV DC bus under voltage
Low AC supply voltage
Low DC bus voltage when supplied by an external DC power supply
OV DC bus over voltage
Deceleration rate set too fast for the inertia of the machine Mechanical load driving
the motor
OI.AC** Drive output instantaneous over current
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-autotune drive to motor
OI.br** Braking resistor instantaneous over current
Excessive braking current in braking resistor
Braking resistor value too small
O.SPd Over speed Excessive motor speed (typically caused by mechanical load driving the motor)
tunE Auto tune stopped before completion Run command removed before autotune complete

t on drive output current
Excessive mechanical load
High impedance phase to phase or phase to ground short circuit at drive output
Drive requires re-autotuning to motor
O.ht1 IGBT over heat based on drives thermal model Overheat software 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
O.ht3 Drive over-heat based on drives thermal model Overheat software thermal model
O.ht4 Power module rectifier over temperature.
cL1 Analogue input 1 current mode, current loss Input current less than 3mA when 4-20 or 20-4mA modes selected
SCL Serial communications loss time-out Loss of communication when drive is under remote control
EEF Internal drive EEPROM trip
Possible loss of parameter values
(set default parameters (see Pr 29 on page 45))
PH Input phase imbalance or input phase loss
One of the input phases has become disconnected from the drive (not dual rated
drives)
rS Failure to measure motors stator resistance
Motor too small for drive
Motor cable disconnected during measurement
C.Err SmartStick data error Bad connection or memory corrupt within SmartStick
C.dAt SmartStick data does not exist New/empty SmartStick being read
C.Acc SmartStick read/write fail Bad connection or faulty SmartStick
C.rtg SmartStick/drive rating change Already programmed SmartStick read by a drive of a different rating
O.cL Overload on current loop input Input current exceeds 25mA
HFxx trip Hardware faults Internal drive hardware fault (see Commander SK Advanced User Guide)
