HVAC Drive H300 305
Issue Number: 3
Power Data Power system configuration data error
220
The Power Data trip indicates that there is an error in the configuration data stored in the power system.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
Power Down Save Power down save error
37
The Power Down Save trip indicates that an error has been detected in the power down save parameters saved in non-
volatile memory.
Recommended actions:
• Perform a 1001 save in Pr mm.000 to ensure that the trip doesn’t occur the next time the drive is powered up.
PSU Internal power supply fault
5
The PSU trip indicates that one or more internal power supply rails are outside limits or overloaded.
*For a parallel power-module system the rectifier number will be zero as it is not possible to determine which rectifier has
detected the fault.
Recommended actions:
• Remove any option modules and perform a reset
• Remove encoder connection and perform a reset
• Hardware fault within the drive – return the drive to the supplier
PSU 24V 24V internal power supply overload
9
The total user load of the drive and option modules has exceeded the internal 24 V power supply limit. The user load
consists of the drive digital outputs and main encoder supply.
Recommended actions:
• Reduce the load and reset
• Provide an external 24 V power supply on control terminal 2
• Remove all option modules

The version number of the generator software that produced the
table is too low. i.e. a table from a newer generator is required that
includes features that have been added to the table that may not
be present.
