Description Cause/Solution/Troubleshoot
Error Encoder
Card EHyb
(52) Invalid encoder
interf
ace identifier
Check for correct encoder connections/pinout. Incorrect
pinout may drag the encoder board power supply down.
Check encoder card connection to control board for bent
or missing pins and proper connection.
Otherwise, the board may be defective and should be
replaced.
Error Encoder
Card Changed EHybC
(59) Indicates the
encoder interface
card has been
changed. This error should automatically clear itself. If not, re-
Enter the read-only setting in parameter LE01.
Error Encoder
Interface EENCC
(35) Loss of encoder
channel or
communication
between encoder
and drive for an
absolute encoder. This error should be accompanied with further
information describing the nature of the fault. Refer to
LE12 Serial Encoder 1 Status for further details.
Error External
Fault EEF
(31) A digital input can
be programmed
to trigger an error. The digital input for an External Fault may come from the
controller or may be jumpered from an inverter or regen
digital output. The cause of the error will be variable.
Identify the source of the External Fault input and the
conditions which would trigger this input.

bypass this fault). Verify keypad operator is seated properly to the
inverter.
Verify connection of the serial comm. to the keypad
operator at port X6C.
Verify there are no bent or missing pins where the
serial comm. cable from the controller plugs into the
keypad operator.
Verify serial comm. between controller and drive.
Verify connection of keypad operator and inverter control
card.
Verify there are no bent or missing pins where the
