CIP Motion UDT_ServoCtrl Tag Listing
UDT_ServoCtrl Tags
The user-defined type for the Kinetix 300 drives and the add-on defined data type for the PowerFlex drives serve
similar function as the UDT_ServoCtrl data type, however their layouts differ. Refer to the specific data types
for more information.
Tag Group Function
Commands
The command tags initiate preprogrammed logic in the device module. The command tags can be set (latch - OTL) in either the device and/or
application module, and the device module will perform the requested action. The device module also clears the command bit (unlatch – OTU).
For example, if the Enable bit is latched, the corresponding device module executes a Motion Servo On (MSO) instruction and unlatches the
Enable bit.
Status
The Status tags are updated by the device module and contain commonly used information that can be referenced by both the device and
application modules.
For example, if the ON status bit is set, the application or device module knows that the drive is fully enabled.
Motion instructions
Placeholders for Motion Instructions. This provides one central group of Motion Instructions that can be used by both the application and device
module.
Miscellaneous data placeholders
Placeholders for commonly used data for the application and device modules. The data placeholder tags are set by default in the PowerUP
routine located in the device module.
