Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Interlocking of NC Ready relay
S
Interlocking of machining
Explanation
Check and correct machine data for axis assignment and spindle assignment.
S
Remedy

S
Perform POWER ON
79 Mode group no. of channel invalid
S
Scan
At POWER ON
S
Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Interlocking of NC Ready relay
S
Interlocking of machining
Explanation
An incorrect assignment (e.g. channel gap) has been made in the channel-specific machine data for "Channel
valid in mode group".
S
Remedy
Check machine data
S
Perform POWER ON
80 Error in C axis definition
S
Scan
At POWER ON and warm restart
S
Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Interlocking of NC Ready relay
S
Machining stops
S
If C axes and spindles are incorrectly assigned, the spindle does not appear in the service display.
Explanation
The C axes assigned to the spindles were either defined as non-existent or fictitious during installation, or the
spindle and assigned C axis mode groups are not identical.
Remedy
Check and correct axis-specific machine data bits 564*, axis-specific machine data 360* and spindle-specific ma-
chine data 453* and 461*.
84 Coupled motion grouping defined wrong
S
Scan
At POWER ON
S
At warm restart
S
Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Interlocking of machining
Explanation
An illegal coupled axis grouping has been set for the assignment of coupled axes in machine data, e.g.:
S
The axes do not belong to the same mode group
S
The axes have different position control resolutions
S
The axes are of different types (linear axis/rotary axis)
S
The axes are declared as being not present
S
The axes are fictitious
S
The leading axis is defined as a coupled axis
Remedy
Correct machine data using the "Coupled motion" function and perform a warm restart (see Start-up Guide).
