Troubleshooting the Drive 13-15
Port 1-6 Net
Loss 71-
76
The network module
connected to DPI port
stopped
communicating.
The fault code indicates
the offending port
number (71 = port 1,
etc.)
1. Check communication
module for proper
connection to external
network.
2. Check external wiring to
module on port.
3. Verify external network
fault.
Power Loss 3 DC bus voltage
remained below 85% of
nominal for longer than
Power Loss Time (185).
Enable/disable with
Fault Config 1 (238).
Monitor the incoming AC
line for low voltage or line
power interruption.
Power Unit 70 One or more of the
output transistors were
operating in the active
region instead of
desaturation. This can
be caused by excessive
transistor current or
insufficient base drive
voltage. 1. Check for damaged
output transistors.
2. Replace drive.
Pwr Brd
Chksum1 104 The checksum read
from the EEPROM does
not match the checksum
calculated from the
EEPROM data. Clear the fault or cycle
power to the drive.
Pwr Brd
Chksum2 105 The checksum read
from the board does not
match the checksum
calculated. 1. Cycle power to the
drive.
2. If problem persists,
replace drive.
Replaced
MCB-PB 107 Main Control board was
replaced and
parameters were not
programmed. 1. Restore defaults.
2. Reprogram parameters.
Shear Pin 63 Programmed Current
Lmt Val (148) has been
exceeded.
Enabled/disable with
Fault Config 1 (238). Check load requirements
and Current Lmt Val (148)
setting.
