DPI port stopped
communicating.
An attached peripheral with
control capabilities via Logic
Source Sel (89) (or HIM
control) was removed.
The fault code indicates the
offending port number (81 =
port 1, etc.)
1.
If module was not
intentionally disconnected,
check wiring to the port.
Replace wiring, port
expander, modules, Main
Control board or complete
drive as required.
2.
Check HIM connection.

The communications card has
a fault.
Check the DPI device event
queue and corresponding fault
information for the device.

➀
➂
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.
Pulse ln Loss
92
Z channel is selected as a
pulse input and no signal is
present.
1.
Check wiring.
2.
Replace pulse generator.

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.

➁
The checksum read from the
board does not match the
checksum calculated.
1.
Cycle power to the drive.
2.
If problem persists, replace
drive.

➁
Main Control Board was
replaced and parameters were
not programmed.
1.
Restore defaults.
2.
Reprogram parameters.

Encoderless Torque Proving
has been enabled but user
has not read and understood
application concerns of
encoderless operation.
1.
Read the attention on page
13-6 relating to the use of
Torque Proving with no
encoder.
Shear Pin

➂
Programmed Current Lmt Val
(148) has been exceeded.
Enabled/disable with Fault
Config 1 (238).
Check load requirements and
Current Lmt Val (148) setting.
