Note: The contouring error threshold has no influence on the positioning ac-
curacy but defines how exactly the travel distance must be kept so that
no error is signaled.
Very low contouring error values may cause frequent error messages.
Parameter
Act. Contouring Error 1109 contains the current contouring error value.
The peak contouring error value can be monitored via parameter
Peak Value Con-
touring Error
1121 in the actual value memory.
With parametersetting
Reset Memory 237 = “18 - Peak Value Contouring Error”,
you can reset the saved value on the optional control unit KP500 or via a communi-
cation interface.
By reducing the acceleration and deceleration values step by step, triggering of the
contouring error can be avoided. The reduction of these values, however, also
changes the motion profile so that it may no longer meet the requirements of the
application. In this case, the mechanical design and the selected drive power must
be checked.
