Check enclosure / drive fans are still functioning correctly.
Force the heatsink fans to run at maximum speed.
Check enclosure ventilation paths.
Check enclosure door filters.
Increase ventilation.
Reduce the selected drive switching frequency.
Ensure
Auto-switching Frequency Change Disable
(05.035) is set to Off.
Reduce duty cycle.
Increase acceleration / deceleration rate parameter values.
Reduce motor load.
Check DC bus ripple.
Ensure all three input phases are present and balanced.
Check the derating tables and confirm the drive is correctly sized for the application.
Use a drive with larger current / power rating.
Trip

Short description
Power stage over temperature
This trip indicates that a power stage over-temperature has been detected. From the sub-trip "xxyzz", the thermistor location is identified by "zz".

Recommended actions:
Check enclosure / drive fans are still functioning correctly.
Force the heatsink fans to run at maximum speed.
Check enclosure ventilation paths.
Check enclosure door filters.
Increase ventilation.
Reduce the selected drive switching frequency.
Ensure
Auto-switching Frequency Change Disable

Reduce motor load.
Check DC bus ripple.
Ensure all three input phases are present and balanced.
Check the derating tables and confirm the drive is correctly sized for the application.
Use a drive with larger current / power rating.
Trip
OI.A1
Value
189
Short description
Current loop overload on analog input 1
If the input current is detected as being > 23mA the input impedance is increased by the hardware to protect the shunt resistor used to measure the current. This action is detected by
the firmware, at which point the shunt is disconnected and a
An Input 1 OI
trip generated.
Recommended actions:
Check control wiring is correct.
Check control wiring is undamaged.
Check
Analog Input 1 Mode
(07.007).
Trip
OI.A2
Value
190
Short description
Current loop overload on analog input 2
Not supported
Trip
OI.aC
Value
3
Short description
Over current at the motor terminals
This trip indicates that the instantaneous drive output current has exceeded the over current threshold.
The over current threshold is the maximum current the drive can measure and is defined by
Full Scale Current Kc
(11.061)
This trip cannot be reset until 10 s after the trip was initiated.
Recommended actions:
Increase acceleration/deceleration rate parameter values
If seen during auto-tune reduce the voltage boost
Check for short circuit on the output cabling
Check integrity of the motor insulation using an insulation tester
Check the motor cable length is within limits for the frame size.
Reduce the values in the current loop gain parameters - (
Torque and current control
(04) )
Trip
OI.br
Value
4
Short description
Over current in the brake IGBT
This trip indicates that an over-current has been detected in the braking IGBT.
This trip cannot be reset until 10 s after the trip was initiated.
Recommended actions:
