Trip
no.PS
Value
236
Short description
No power stage detected by the Control board
This trip is generated if the control board cannot establish a communication link with the power stage within 5 seconds of powering up.
Trip
None
Value
0
Short description
No trip recorded
No trip. Trip log has a value of zero because there has been no trip since the drive left the factory or the trip log has been cleared by setting parameter 10.038 to 255.
Trip
O.Ld1
Value
26
Short description
Overload on 24V or digital outputs
This trip indicates that the total current drawn from the AI adaptor 24V or from the digital output has exceeded the limit.
Sub-trip
Reason
1
Digital output or 24V supply load on control terminals is too high.
2
AI adptor 24V load is too high
Recommended actions:
Check total loads on digital outputs and 24V.
Check control wiring is correct.
Check output wiring is undamaged
Trip
O.Spd
Value
7
Short description
Motor over speed
In open loop mode, if
Post Ramp Reference
(02.001) exceeds the threshold set in
Over Frequency Threshold
(03.008) in either direction an Over Speed trip is produced. In RFC-A
mode, if
Estimated Frequency
(03.002) exceeds the threshols set in
Over Frequency Threshold
(03.008) either direction an Over Speed trip is produced.
If
Over Frequency Threshold
(03.008) is set to 0.00 the threshold is then equal to 1.2 x VM_SPEED_FREQ_REF[MAX].
Recommended actions:
• Check that the motor is not being driven by another part of the system.
• Reduce the Frequency Controller Proportional Gain
Frequency Controller Proportional Gain Kp1
(03.010) to reduce the frequency overshoot (RFC-A mode only).
Trip
Oh.dc
Value
27
Short description
Overload on DC bus components
This trip indicates a DC bus component over temperature based on a firmware thermal model. The drive includes a thermal protection system to protect the DC bus components
within the drive. This includes the effects of the output current and DC bus ripple. The estimated temperature is displayed as a percentage of the trip level in
Percentage Of d.c. Link Thermal Trip Level
(07.035). If this parameter reaches 100% then an
OHt dc bus
trip is initiated. The drive will attempt to stop the motor before tripping. If the
motor does not stop in 10s then the drive will trip.

00: DC link thermal model gives
OHt dc bus
with sub-trip 0.
Recommended actions:
Check the AC supply voltage balance and levels
Check DC bus ripple level
Reduce duty cycle
Reduce motor load
Check the output current stability. If unstable:
Check the motor map settings with motor nameplate (
Motor Rated Frequency
(05.006) ,
Motor Rated Current
(05.007) ,
Motor Rated Speed
(05.008)
,
Motor Rated Voltage
(05.009) ,
Motor Rated Power Factor
(05.010) , and
Number Of Motor Poles
(05.011) ).
Disconnect the load and complete a rotating auto-tune (
Auto-tune
(05.012) = 2 ).
Disable slip compensation (
Slip Compensation Level
(05.027) = 0.0%).
Disable dynamic V to F operation (
Flux Optimisation Select, Dynamic V To F Select
(05.013) = 0).
Select fixed boost (
Open-loop Voltage Mode
(05.014) = Fixed (2)).
Select high stability space vector modulation (
High Stability Space Vector Modulation
(05.019) = 1).
Trip
Oht.C
Value
219
Short description
Control board over temperature
This trip indicates that a control stage over-temperature has been detected if
Cooling Fan control
(06.045) = 0.
This trip causes the option module to go to standby and
Potential Drive Damage Conditions
(10.106) bit 1 to be set.
Recommended actions:
Increase ventilation by setting
Cooling Fan control
(06.045) > 0.
Trip
Oht.I
Value
21
Short description
Inverter IGBT junction over temperature
This trip indicates that an IGBT junction over-temperature has been detected based on a firmware thermal model.
