/ Description
Invalid encoder
interface identifier
Indicates the
encoder interface
card has been
changed.
Loss of encoder
channel or com-
munication be-
tween encoder
and drive for an
absolute encoder.
A digital input can
be programmed
to trigger an error.
This message
indicates that se-
rial communica-
tion between the
keypad operator
and the drive or
the drive and the
elevator control
has been lost
(See parameter
LX09 Ser.Com
Watchdog Time to
bypass this fault).
Cause/Solution/Troubleshoot
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.
This error should automatically clear itself. If not, re-
Enter the read-only setting in parameter LE01.
This error should be accompanied with further informa-
tion describing the nature of the fault. Refer to LE12 Se-
rial Encoder 1 Status for further details.
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.
Verify keypad operator is seated properly to the in-
verter.
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 key-
pad operator connects to the control card.
