116* Contour monitoring
Scan
In all modes
S
When decelerating
S
When accelerating
S
At velocities greater than in NC machine data "Contour threshold speed"
S
Effect
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Setpoint 0
S
The control enable is removed after the time stored in NC machine data "Control enable cutout delay" has
elapsed
S
Follow-up operation
S
Explanation
At a velocity greater than in NC machine data "Contour threshold speed", the NC machine data
"Tolerance band contour monitoring" was exceeded
S
When accelerating or decelerating the axis has not reached the new speed within the time defined by the K
factor
S
Remedy
Increase NC machine data "Tolerance band contour monitoring"
S
Check K (servo gain) factor
V
S
Check the optimization of the speed controller
S
Check the actual values (pulse encoder)
S
Check the free movement of the axes
S
Reduce acceleration
120* Axis specification illegal
S
Scan
At POWER ON
S
Effect
Axis is not processed
S
Controller disable for the relevant axis
S
Mode Group Ready removed
S
Interlocking of NC START
S
Explanation
Specification of MD200x or MD384x in the relevant axis missing.
Example: MD2000 = 01020101 and MD384 = 00000000
S
Specification of module number in MD200x or MD384 is greater than the number of measuring circuit modules
present.
Example: MD2000 = 04010000 and 3 measuring circuit modules are plugged in.
S
Specification of the connection number in MD200x or MD384 is greater than the number of connections on the
relevant module.
Example: MD3840 = 02070000; the 2nd measuring circuit module is a SPC module and therefore has only 6
connections.
S
Connection number for an input is assigned to an output and vice versa.
Example: MD3840 = 01030000; the 1st measuring circuit module is a HMS module and connection number 3
there is an input connection.
S
Input or output assignment is not compatible with the plug-in submodule.
Example: MD2000 = 01040101; the 1st measuring circuit module is a HMS module with output submodule
Servo-Command 6FX1132–5BAxx on its submodule slot 1.
S
Remedy
Check and correct MD200x and MD384x of the relevant axis. Both these machine data must be
specified or must be zero. In addition, they must agree with the hardware configuration.
Note
Applies up to SW 2 only
128* Measuring circuit not available
S
Scan:
At POWER ON
S
Effect
Axis is not processed
S
Control disable for the axis concerned
S
NC Ready 2 removed
S
Interlocking of NC START
S
Interlocking of Mode Group Ready
S
Interlocking of NC RDY relay
S
Explanation
MD200x or MD384x indicates an empty slot on a measuring circuit module containing submodules.
Example: MD3840 = 01090000; the 1st measuring circuit module is a HMS module with submodule slot 2
empty.
S
Measuring circuit module removed or defective.
S
Remedy
Compare and correct MD200x or MD384x with hardware configuration.
