CncKernel error 70024 /70159 when use CncPortal control Rexroth servo axis

[ZhangJack]

Dear colleague：

   When I use NexeedCncPortal to control Rexroth servo axis , It can run nomally until I control on/off the station,then it appear error :CncKernel error 70024 /70159. But the Rexroth servo state is Ab/AF,not detect any error.The CncKernel error appeared in the TwinCat error list box like below ,I compare the plc program and servo parameter  still cannot solve the error problem.Though the error can be reset by the clearError button,but still want to solve this problem. Thanks
