Supplementary Functions13-613.4 Current Value UpdateThe current value update function is a function to change the current value controlled by thepositioning unit to a desired (preset) value.Refreshing the current value requires data writing to the unit memory. Current value update area (Unit memory)Unitmemory no. (Hex) Name DescriptionUM 000C0 Current value updaterequest flagOnly when the corresponding bit for each axis changes to 1 from 0,the current coordinate controlled by the positioning unit to thefollowing current value.After the change, the positioning unit will clear the correspondingbits to 0 automatically.bit Name Default Description0 Current value updaterequest for 1st axis0 0: No change1: Changes thecorrespondingcoordinate origin.(After change, thepositioning unit clearsthe corresponding bitsto 0 automatically.)1 Current value updaterequest for 2nd axis02 Current value updaterequest for 3rd axis03 Current value updaterequest for 4th axis015 to 4 − − −UM 000C8 Current value updatecoordinate of 1st axis Stores the coordinate to be preset as the current value of 1st axis.UM 000C9UM 000CA Current value updatecoordinate of 2nd axis Stores the coordinate to be preset as the current value of 2nd axis.UM 000CBUM 000CC Current value updatecoordinate of 3rd axis Stores the coordinate to be preset as the current value of 3rd axis.UM 000CDUM 000CE Current value updatecoordinate of 4th axis Stores the coordinate to be preset as the current value of 4th axis.UM 000CFUM 000D6 Current value updatecoordinate of virtual axis Stores the coordinate to be preset as the current value of virtual axis..UM 000D7 Current value update procedure1. Write a coordinate to be preset in the current value update coordinate area of the axis toupdate the current value.2. Preset the target axis bit to 1 in the current value update request flag area. As the currentvalue update process is performed for the axis that is 1 in the current value request flagarea, do not set any bit to 1 other than the target axis.3. The current value after unit conversion in each axis information and monitor area ischanged to the specified current value.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
