Error Cause of error
number
2868 You tried to start tool measurement
although the REF coordinates of
one or more rotary axes (or parallel
axes) do not agree with the
coordinates defined in machine
parameters MP6586.x.
189 E: During data transfer with BCC,
the <NAK> signal was received 15
times in succession.
A to H w/o E: error code of the
receiver module with one of the
following causes:
The baud rate setting of the
TNC and peripheral device do
not match.
Parity bit wrong.
Erroneous data frame
(e.g.: no stop bit).
The receiver module of the
interface is faulty.
K: During transmission of an error
to the TNC, the <1> character was
not transmitted after the <ESC>
character.
L: After the error sequence
<ESC<1>< an incorrect error
number was received (error
numbers 0 to 7 are permitted).
M: During data transfer with BCC,
the <NAK< signal was transmitted
15 times in succession.
N: An expected acknowledgment
>ACK< or <NAK< was not
transmitted by a certain time.

not be switched to ready condition.
2656 The power supply for a spindle
or for an axis is ready for operation

2642 After a "safe stop" the inverter did
not return to the ready state.
2289 The inverter is still ready for
operation, although it is supposed
to be switched off.

could not be switched to ready
condition.
2654 The power supply for a spindle is
ready for operation although it
ought to be switched off.
Corrective action
In the Manual operating mode,
position the rotary or parallel axes
so that the REF coordinates of the
axes agree with the machine
parameter values. Then restart the
measuring program.
Data transfer channel must be
checked.
