Chapter 5 Positioning Instructions
5 - 81
(2) Sample Instruction
•The sample program below show exemplary operation of position override.
(c) Sample Program
(d) Program Operation
•At the rising edge of the ‘indirect start-up’ signal which is the reference signal for indirect start-up,
positioning X-axis is started up indirectly by operation step No. 1.
•If the rising edge of the ‘position override reference’ signal used as the reference signal for the
position override instruction occurs before the present position reaches 100,000[Pulse] during
operation, the operation continues by changing the target position of the step presently in
operation to 100,000. Take care that the target position value of the No.1 step set up with the
positioning parameter itself is not changed.
•If position override instruction is executed after the present position has passed 100,000[Pulse],
deceleration stop occurs.
•If position override instruction is executed while the operation state is in dwelling, error code 362 is
outputted to STAT. To prevent this, the start-up contact should be connected with the X-axis dwell
status flag as normally closed (B contact) in the program.
