Communication between the LCP and the frequency converter is lost.
The LCP key is disabled. One of the LCP keys is disabled in parameter group 0-4* LCP Keypad.
Data copy failure: Occurs when data is copied from frequency converter to LCP, or from LCP to frequency
converter (parameter 0-50 LCP Copy).
Invalid LCP data: Occurs when data is being copied from LCP to frequency converter (parameter 0-50 LCP Copy).
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.
An operation is issued via LCP to write a value to a parameter that is read-only.
LCP, serial communication, or fieldbus communication attempts to update the same parameters at the same time.
The parameter value that is input via the LCP is invalid.
The parameter value that is input via the LCP exceeds limits.
The LCP copy operation cannot be conducted when the frequency converter is running.
A notification that the LCP Copy process is finished.
The parameter cannot be changed while the frequency converter is running.
The password that is input via the LCP is incorrect.
Possible cause
LCP stop
Missing start signal (standby)
Motor coast signal active (coasting)
Wrong reference signal source
Motor rotation limit
Active reversing signal
Wrong motor phase connection

Description
Test
Check if [Off] has been pressed.
Check parameter 5-10 Terminal 18
Digital Input for correct setting for
terminal 18 (use default setting).
Check parameter 5-12 Terminal 27
Digital Input for correct setting for
terminal 27 (use default setting).
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?
Check that parameter 4-10 Motor
Speed Direction is programmed
correctly.
Check if a reversing command is
programmed for the terminal in
parameter group 5-1* Digital inputs.
Change parameter 1-06 Clockwise
Direction
Solution
Press [Auto On] or [Hand On]
(depending on operating mode) to
run the motor.
Apply a valid start signal to start the
motor.
Apply 24 V on terminal 27 or
program this terminal to No
operation.
Program correct settings. Set preset
reference active in parameter group
3-1* References. Check for correct
wiring. Check scaling of terminals.
Check reference signal.
Program correct settings.
Deactivate reversing signal.
