Sub-
Reason
trip
1 The inductance ratio or difference is too small when the drive has been started in sensorless mode.
2 The saturation characteristic of the motor cannot be measured when the drive has been started in sensorless mode.
The inductance ratio or difference is too small when an attempt is made to determine the location of the motor flux
during a stationary auto-tune in RFC-S mode. This trip is also produced when the inductance ratio or inductance
3 difference is too small when carrying out a phasing test on starting in RFC-S mode. If position feedback is being
used the measured value for Position Feedback Phase Angle (03.025) may not be reliable. Also the measured
values of Ld (05.024) and No-load Lq (05.072) may not correspond to the d and q axis respectively.
The direction of the flux in the motor is detected by the change of inductance with different currents. This trip is
4 initiated if the change cannot be detected when an attempt is made to perform a stationary auto-tune when position
feedback is being used, or to perform a phasing test on starting in RFC-S mode.
Trip Inductor Too Hot
Value 93
Short description
Regen inductor overload. See Inductor Thermal Time Constant.
Trip Inter-connect
Value 103
Short description
Multi-power module drive interconnection cable error. The sub-trip "xx.0.00" indicates which power module has detected the fault where xx is the power module
number. It should be noted that this trip is also initiated if the communication fails either when a rectifier signals a fault or a trip us reset. In this case the sub-trip is
the number of modules that are still communicating correctly.
Trip Island
Value 160
Short description
This trip indicates that a regen system is connected to an islaned supply. The sub-trips indicate the reason for the trip.
Sub-
Reason
trip
1 Island detection system has been enabled and detected an island condition
The minimum synchronisation voltage is non-zero and the supply voltage has been below this threshold and been
2
simulating its own supply synchronisation for more than 2.0s.
Recommended actions:
Check the supply / supply connections to the regen drive.
Trip Keypad Mode
Value 34
Short description
If keypad reference mode is enabled (Reference Selected Indicator (01.049) = 4 or 6) (i.e. Reference Selector (01.014) is set to 4 or 6 if motor map 1 is selected,
or M2 Reference Selector (21.003) is set to 4 or 6 if motor map 2 is selected) and the keypad removed, then this trip is initiated.
Recommended actions:
Re-install keypad and reset.
Change Reference Selector (01.014) to select the reference from another source.
Trip Line Sync
Value 39
Short description
This trip indicates that the inverter has lost the synchronization with the ac supply in Regen mode.
Recommended actions:
Check the supply / supply connections to the regen drive.
Trip Low Load
Value 38
Short description
This trip is initiated if the low load detector is set up to produce a trip on low load detection and this condition occurs. See Enable Trip On Low Load (04.029).
Trip Motor Too Hot
Value 20
Short description
This trip indicates a motor thermal overload based on the Rated Current (05.007) and Motor Thermal Time Constant 1 (04.015). Motor Protection Accumulator
(04.019) displays the motor temperature as a percentage of the maximum value. The drive will trip on Motor Too Hot when Motor Protection Accumulator
(04.019) gets to 100%.
