Control
system
00 0 00: Phase loss detected based on control system feedback. The drive
attempts to stop the drive before tripping unless bit 2 of
ActionOnTripDetection (10.037) is set to one.
Power system 01 0 10: Phase loss has been detected by the rectifier module.
Input phase loss detection can be disabled when the drive is required to operate from the DC supply or from a single phase supply in InputPhaseLossDetectionMode (06.047).
Recommended actions:
Check the AC supply voltage balance and level at full load.
Check the DC bus ripple level with an isolated oscilloscope.
Check the output current stability.
Reduce the duty cycle.
Reduce the motor load.
Disable the phase loss detection by setting InputPhaseLossDetectionMode (06.047) to Disabled.
Trip PSU
Value 5
Short description Internal Power Supply fault
This trip indicates that one or more internal power supply rails are outside limits or overloaded.
Source xx y zz
Power system 01 0 10: Internal power supply overload
Recommended actions:
Hardware fault within the drive - return the drive to the supplier.
Trip r.All
Value 227
Short description RAM allocation failure
An option module, derivative image or user program image has requested more parameter RAM than is allowed. The RAM allocation is checked in order of resulting sub-trip
numbers, and so the failure with the highest sub-trip number is given. The sub-trip is calculated as (parameter size x 1000) + (parameter type x 100) + sub-array number. Note that if
this trip occurs, all menu customisation provided by option modules, the derivative image or the user program image is not used. The tables below show the values corresponding to
the parts of the sub-trip number.
