4th axis is not rotating continuosly

[enaries]

Hi
I am using a generic UG post for 4th axis. It keeps going back to zero every time it finishes 360 degrees. Is there any way i can make it continuous.My 4th axis (Rotary Chuck) is set parallel to X axis. Can anyone help me sharing a post file or writing a post for this.
Thanks

If it is a postbuilder postprocessor consider altering mom_kin_4th_axis_max_limit and mom_kin_4th_axis_min_limit in the tcl file. It might be necessary to alter the def file too, check how the 'fourth_axis' address is configured.
