3.5.1 Position monitoring for operation with lag
The machine parameters MP1710 and MP1720 determine the ranges for the continuous position
monitoring in the machine (lag monitoring). The monitoring is active as soon as the axes are under
the control of the position control loop.
If the limits of parameter MP1710 are exceeded, the error message
"Positioning error"
will appear and the machine stops. The error message can be cancelled by the "CE" key.
If the limit of parameter MP1720 is exceeded, the flashing error message
"Gross positioning error A"
appears.
This error can only be cancelled by switching off the control. An entry value of approx. 1 to 1.4 times
lag for rapid traverse is realistic. MP1720 is larger than MP1710.
