Present Position
Latch (LATCH)
The present position of the specified axis is stored.
Command type Single execution command
Format LATCH_[<axis name>]<latch position storing variable>{I<latch check start
position>}
{J<latch check end position>};
Ex: LATCH_[J01]#DL0000;
Operand Axis name: J01 to J32
Note (1) Word data is extended to long word data with a sign in the MC Unit.
(2) The actual value is determined by the setting value of the parameter
[P5AA02: Position command decimal point position].
(3) There is no influence. ABL specification is always used.
Description • The position of the specified axis is stored.
• The latched position is assigned in Latch position storing variable.
• Latch signal is accepted only in the sections specified in Latch check start
