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 dierences.
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 eldbus 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.
