8) Positioning direct start (POSDST)
Function block Description
Input
REQ : Execute POSDST function block
CH: Sets the channel (0 ~ 1)
METH : Absolute/Incremental coordinate designation
(0:Absolute, 1:Incremental)
ADDR : Positioning address
(-2,147,483,648 ~ 2,147,483,647)
VEL : Velocity ( 0 ~ 100,000)
Output
DONE: Turns On after the function block is executed without error, and
turns Off if an error occurs or there is no execution command.
STAT: Displays error status
(1) Functions
• When input condition turns on (rising edge), corresponding Ch. starts positioning by designated coordinate, address and speed
(2) Example program
• When input condition (%MX000) turns on, Ch. 0 outputs 100,000 pulses by designated coordinate, forward direction
and speed of 100 kpps.
• Acceleration/deceleration time is applied by corresponding parameter.
