7.4 Error Code List
LCP-related errors are shown in the format of
Err XX
, where XX indicates the error number. The LCP errors do not affect the
operation of the frequency converter.
LCP error code
Description
Err 84
Communication between the LCP and the frequency converter is lost.
Err 85
The LCP key is disabled. One of the LCP keys is disabled in
parameter group 0-4* LCP Keypad
.
Err 86
Data copy failure: Occurs when data is copied from frequency converter to LCP, or from LCP to frequency
converter (
parameter 0-50 LCP Copy
).
Err 87
Invalid LCP data: Occurs when data is being copied from LCP to frequency converter (
parameter 0-50 LCP Copy
).
Err 88
LCP data incompatible: Occurs when data is being copied from LCP to frequency converter (
parameter 0-50 LCP
Copy
), typically because data is moved between frequency converters that have major software differences.
Err 89
An operation is issued via LCP to write a value to a parameter that is read-only.
Err 90
LCP, serial communication, or fieldbus communication attempts to update the same parameters at the same time.
Err 91
The parameter value that is input via the LCP is invalid.
Err 92
The parameter value that is input via the LCP exceeds limits.
Err 93
The LCP copy operation cannot be conducted when the frequency converter is running.
donE
A notification that the LCP Copy process is finished.
NWrun
The parameter cannot be changed while the frequency converter is running.
Err.
The password that is input via the LCP is incorrect.

7.5 Troubleshooting
Symptom
Possible cause
Test
Solution
Motor not running
LCP stop
Check if [Off] has been pressed.
Press [Auto On] or [Hand On]
(depending on operating mode) to
run the motor.
Missing start signal (standby)
Check
parameter 5-10 Terminal 18
Digital Input
of correct setting for
terminal 18 (use default setting).
Apply a valid start signal to start the
motor.
Motor coast signal active (coasting)
Check
parameter 5-12 Terminal 27
Digital Input
for correct setting of
terminal 27 (use default setting).
Apply 24 V on terminal 27 or
program this terminal to
[0] No
operation
.
Wrong reference signal source
Check the following:
•
The reference signal is local,
remote, or bus reference?
•
Preset reference is active?
•
Terminal connection is correct?
•
The scaling of terminals is correct?
•
The reference signal is available?
Program correct settings. Set preset
reference active in
parameter group
3-1* References
. Check for correct
wiring. Check scaling of terminals.
Check reference signal.
Motor is running in
the wrong direction
Motor rotation limit
Check that
parameter 4-10 Motor
Speed Direction
is programmed
correctly.
Program correct settings.
Active reversing signal
Check if a reversing command is
programmed for the terminal in
parameter group 5-1* Digital inputs
.
Deactivate reversing signal.
Wrong motor phase connection
Change
parameter 1-06 Clockwise
Direction
.
