Will Not Scan with Gradient Errors.
Error message
2238633 The Z axis GRAM is reporting a coil over current fault. Error: 2238633 Host: mr1 Process: NSP File: HPC PORT ID:GAP/GIP/GP Line: 1041 The Z axis GRAM is reporting a coil over current fault. Try scan again once. If error occurs again, try a standard spin echo with a larger FOV. If error persists, possible gradient driver fault. 2238663 The Z axis GRAM is reporting the current is distorted over a period of time. Error: 2238663 Host: mr1 Process: NSP File: HPC PORT ID:GAP/GIP/GP Line: 1049 The Z axis GRAM is reporting the current is distorted over a period of time. The current is not what the DAC is requesting. Possible gradient driver failure. Another GRAM fault reported in the log could be the cause of this fault. 2238636 The Z axis GRAM is reporting a shoot thru fault. Error: 2238636 Host: mr1 Process: NSP File: HPC PORT ID:GAP/GIP/GP Line: 1042 The Z axis GRAM is reporting a shoot thru fault. If under voltage fault also occurred for this axis, possible fatal GRAM fault.
