# ID 120740

Not all axes required for workspace monitoring are available. No monitoring possible.
Description | The relevant axes of all active work and protective areas must be available in the NC channel when workspace monitoring is used (see FCT-C14). Otherwise, control area monitoring is not possible. This error message is generated with a path motion.

See also [PROG// Section: Definition of a control area]

Example:

#CONTROL AREA BEGIN [ID1 PROT POLY MIN_EXCUR=0 MAX_EXCUR=360]

G01 F1000 G90

X = 0 Y=0

X = 0 Y=100

X = 100 Y=100

X = 100 Y=0

X = 0 Y=0

#CONTROL AREA END

#PUT AX [Y]

…

#CONTROL AREA ON [ID1]

G0 X100 (Error 120740)

Correct:

#CONTROL AREA BEGIN [ID1 PROT POLY MIN_EXCUR=0 MAX_EXCUR=360]

G01 F1000 G90

X = 0 Y=0

X = 0 Y=100

X = 100 Y=100

X = 100 Y=0

X = 0 Y=0

#CONTROL AREA END

#PUT AX [Y]

…

#CONTROL AREA ON [ID1]

#CALL AX [Y,2,1]

G0 X100
