7.4 Error Code List

LCP-related errors are displayed in the format of Err XX, where XX indicates the error number.
Error
number
84 The connection between frequency converter and LCP is lost.
85 One of the LCP keys has been disabled via parameters in parameter group 0-4* LCP Keypad.
86 Data copy failure: Occurs when data is copied from frequency converter to LCP, or from LCP to frequency converter
(0-50 LCP Copy).
87 Invalid LCP data: Occurs when data is being copied from LCP to frequency converter (0-50 LCP Copy).
88 LCP data incompatible: Occurs when data is being copied from LCP to frequency converter (0-50 LCP Copy), typically
because data is moved between frequency converters that have major software differences.
89 An operation is issued via LCP to write a value to a parameter that is read-only.
90 LCP, serial communication, or field bus communication attempt to update the same parameters at the same time.

Quick Guide
Description
Possible cause
Check if [Off] has been pressed.
Check 5-10 Terminal 18 Digital Input
for correct setting for terminal 18
(use default setting).
Check 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 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 1-06 Clockwise Direction
Check output limits in 4-14 Motor
Speed High Limit [Hz] and 4-19 Max
Output Frequency
Check reference input signal
scaling in 6-** Analog I/O mode and
parameter group 3-1* References.

Test
Press [Auto On] or [Hand On]
(depending on operation 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.
Program correct limits.
Program correct settings.
