{HF19}

The HF19trip indicates that the drive firmware is partially or completely deleted. The drive is now in its bootloader

and is waiting for a new image to be downloaded using UniMConnect. Once a new image is downloaded, the drive

can run normally.

When the drive is subsequently powered up a StoredHF trip is initiated where the sub-trip number is the number of the HF trip that last occurred. This trip will occur

at every power-up until it is reset. The trip can only be reset by first entering 1299 into Parametermm.000 (mm.000). If the drive is powered up and a StoredHF trip

occurs, OnboardUserProgram:Enable (11.047) is reset to zero to prevent the on-board user program from running. This ensures that the user program can be

changed or erased in case it causes an HF trip at every power-up.

Trip descriptions

Trips shown in the table below can be generated either from the drive control system or from the power system. The sub-trip number which is in the form xxyzz is

used to identify the source of the trip. The digits xx are 00 for a trip generated by the control system or the number of a power module if generated by the power

system. If the drive is not a multi-power module drive then xx will always have a value of 1 if the trip is related to the power system. The y digit is used to identify the

location of a trip which is generated by a rectifier module connected to a power module. Where the y digit is relevant it will have a value of 1 or more, otherwise it will

be 0. The zz digits give the reason for the trip and are defined in each trip description.
