Programmed positive software limit switch is out of permissible value range.
Description | Use G99 to change positive (upper) software limit switches. A positive software limit switch can only be reduced. This means a reduction in range. Use the parameter P-CHAN-00498 to influence the behaviour of programmed software limit switches
Response | Class | 1 | Output the warning and limit the positive software limit switch
Solution | Class | 1 | Check and modify the value for G99 in the NC program. Increase the range by using G99 to set the parameter P-CHAN-00498 to 0.
Parameter | %1: | Logical axis number [-]
Logical axis number (P-AXIS-00016) of affected axis
%2: | Error value [0.1 µm or 0.0001°]
Programmed value for the software limit switch
%3: | Upper limit value [0.1 µm or 0.0001°]
Limiting value
Error type | 1, Error message from NC program.
