13. POSITIONING MODE
(c) Automatic continuous positioning operation
When "1" or "3" is set to the auxiliary function in the point table, positioning of the next point table No. is
executed continuously.
When "1" or "3" is set to the auxiliary function in the point tables up to No.6, a maximum of 7 points of
automatic continuous positionings are possible. Set "0" to the auxiliary function in the last point table.
As an example, the operation in the absolute value command system is shown using the set values in
the following table. Here, the point table No.1 uses the absolute value command system, the point table
No.2 the incremental value command system, and the point table No.3 the absolute value command
system.

Note 1. External input signal detection delays by the input filter setting time of parameter No. PD19. Additionally, make up a
sequence that changes the point table selection ahead of time by considering delays in output signal sequence from the
PC or PLC...etc and variations of a signal change due to hardware.
2. If the over load tough drive function is enabled by setting parameter No. PA04 to " 1", INP turn-on delays during the
overload tough drive. MEND turn-on also delays together with INP. However, MEND does not turn ON during automatic
continuous positioning operation.
