Move Absolute(DINT) |
 |
| Name | Move Absolute(DINT): MD_CPU011_MoveAbsolute_DINT |
| Basic Function | Executes positioning using absolute movement. | ||
| Symbol |  |
||
| Originates from | Tsunagi Lab Europe | ||
| Created by | OEE-HQ HvB (creation and testing) | ||
| File Name | MD_CPU011_MoveAbsolute_DINT.cxf | ||
| Applicable models | CPU Unit | CJ2M-CPU Unit version 2.0 or higher with max. two CJ2M-MD211 (NPN) or CJ2M-MD212 (PNP) |
|
| CX-Programmer | Version 9.1.2 or higher | ||
| Conditions for usage | None. | ||
| Function Description | Executes positioning on the axis of the specified Axis No. (Axis) with the specified Position command (Position), Speed command (Velocity), Acceleration rate (Acceleration), and Deceleration rate (Deceleration) when Start (Execute) is turned ON (using the selected Pulse output method). The Positioning completed (Done) is turned ON when positioning by this FB is completed (i.e., target position reached). The Error flag (Error) will be turned ON and Error code (ErrorID) will be output when an error related to this FB occurs. These statuses, Positioning completed (Done)/ Error flag (Error)/ Error code (ErrorID), will be reset when Start (Execute) is turned OFF. If Start (Execute) was turned OFF before positioning is completed, the status will be set for at least one cycle when a corresponding condition occurs.

||
| Kind of FB definition | Connect Always ON type Connect the EN input to the Always ON Flag (P_ON). The same instance cannot be used in two or more places. |
||
| FB Precautions | When using the Pulse output 0&1 or 2&3 simultaneously, use the same Pulse output method for them. The MD_CPU0* function blocks are offered 'as is' and may serve as a basis for development. Users should previously test its adequacy to the final application. Omron can not be held responsible in case of malfunction. |
||
| EN input condition | • Connect the EN input to the Always ON Flag (P_ON). • If a different type of bit is connected to EN, the FB outputs will be maintained when the connected bit is turned OFF. |
||
| Application example | Turning the start trigger from OFF to ON will start operating the Servomotor connected to the Pulse output 0 on the CJ1M-CPU Unit with absolute movement.

Output Variables
| Name | Variable name | Data type | Range | Description |
|---|---|---|---|---|
| ENO | ENO | BOOL | 1(ON) :FB operating normally 0(OFF): FB not operating normally |
|
| Positioning completed | Done | BOOL | 1 (ON) indicates that positioning has been completed. | |
| Error flag | Error | BOOL | 1 (ON) indicates that an error has occurred in the FB. | |
| Error code (May be omitted) | ErrorID | WORD | The error code of the error occurred in the FB will be output. For details of the errors, refer to the sections of the manual listed in the Related manuals above. When Unit No. or Axis. No. is out of the range, #0000 will be output. |
