Name Description
Possible Causes & Corrective Action
LS CHK Setup
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.
Inconsistent Parameter Settings
 Verify Parameters settings in menu A1, A2,
A3, A4, and A6 are correct
LS Cube Data
The cube data for the line side
processor is invalid. Invalid Cube ID
Verify LS Cube ID is seated correctly and not
damaged
LS Cube ID
The drive is reading the cube
ID and it doesn’t match the size
of the power module Invalid Cube ID
 Verify LS Cube ID is seated correctly and not
damaged
 Verify LS Cube ID in U7 is correct version
 Replace product interface board
LS Curr Reg
Inability to regulate AC side to
match incoming line 3-phase
voltage.
Faulty current feedback signals
 Verify connections to current transducers
Incorrect DC Bus Voltage reading
 Measure the dc bus with a meter
 Compare that with the value on the digital
operator, DC BUS VOLTS (D3) or MS BUS
VOLTS (D2)
Parameter Settings
 Increase DC BUS V BOOST (A5)
 Set BUS VREF SOURCE (A5) to TRK VIN
PARAM
 Decrease values in Id REG INTGRL GAIN
(A5) and Iq REG INTGRL GAIN (A5)
 Decrease values in Id REG PROP GAIN (A5)
and Iq REG PROP GAIN (A5)
External Relay Timing
 Check for improper external relay timing
 Verify UTM is closed and verify the correct
operation of the power poles
Check Wiring
 Missing jumper wire at Customer Interface
Board PCB, TB2
 Missing jumper at JP9 on Product Interface
Board, A3
Hardware / software not at the latest revision
 Check with tech support to verify that the drive
has the correct version product interface
boards and software. It should have
46S03954-0030 RV07 or later.
 Verify UTM is properly closing, check the
power poles for damage
LS DCU Data
The DCU parameters
checksum is invalid on the line
side. Parameters Corrupted
Check & re-enter Line Side parameters and
power cycle the drive
