TECHNICAL NOTE
• Ten words are used as working registers for this function, starting at the address
in Data10W
<DEF_POS> Input and Output Register Map
Output Registers
The following registers are used as outputs from the function block. They can be
monitored by the LadderWorks program to check the execution of the function.
Output Type Description
DONE Bit Indicates the Define Position Procedure has completed
successfully
RUNNING Bit Indicates the Define Position Procedure is in process.
ERROR Bit Latches high if any error occurs in block.
Input Registers
The following registers are used as inputs to the function block. They select the options
and set necessary parameters internally.
Input Type Description Range and State
EXECUTE Bit Block enable – Block cannot
execute unless this is TRUE. Rising edge initiates
TRUE – Block enable
FALSE – Block disable, set all
outputs to zero and off
ABENC Bit For power up operational
purposes the existence of
Absolute Encoder on this axis
needs to be known.
TRUE – An absolute encoder is
mounted on the servomotor for this
axis.
FALSE – An incremental encoder
is mounted on the servomotor for
this axis.
AXIS Word Axis number related to the block. 1 to 16
REQPOSIT Long The Desired Position the Axis is
to be set at. For linear axis, the value can be
–2
31 to (2 31 –1)
For a Rotary Axis the value must
be 0 to the PERIOD (ML***06)
defined in the RDA
DATA10W Address Address of the first working
register. Ten (10) words of register space
are used by this function.
