The hardware has detected a 
ground fault on the line side 
power bridge. 

 

Inspect and measure for physical voltage 
breakdown damage on IGBTs and DC bus  

The DC bus did not charge up 
within the expected time.

 

 

Verify that the setting for INPUT L-L VOLTS 
(A5) is correct  

 

Verify that the PCM contactor is activated 
during a pre-charge attempt 

 

Verify that pilot relay K1 on PCB A8 is 
functioning 

CAUTION: There may be a short circuit on the DC 
bus.  Inspect for physical damage.

 

This fault is logged when a 
new program is loaded to the 
line side processor, and the 
default data is loaded for the 
parameter values.

 

 

Verify Parameters settings in menu A1, A2, 
A3, A4, and A6 are correct 

The power interface board has 
detected a missing or loose 
connector on the line side. 

 

Verify connectors are connected 

 

Verify connectors are properly seated 

The cube data for the line side 
processor is invalid. 

 

Verify LS Cube ID is seated correctly and not 
damaged 

The generation of this fault is 
indicative of a bad processor 
board. 

 

Indicates a bad processor board 

Measured current does not 
match the command current. 

 

Verify that motor contactor is closing 

 

Verify motor contactor is not opening 
unexpectedly 

 

Verify that reported drive current is zero when 
drive is not operating 

 

Verify connections to current transducers 

 

Check gate power supply 

 

Measure the dc bus with a meter 

 

Compare that with the value on the digital 
operator, DC BUS VOLTAGE (D2) 

 

Verify motor nameplate values (A6) are 
entered correctly 

 

Check for improper external relay timing 

 

Missing jumper wire at Customer Interface 
Board PCB, TB2 

The DCU parameters 
checksum is invalid on the line 
side. 

 

Check & re-enter Line Side parameters and 
power cycle the drive
