13. POSITIONING MODE
3) Operation
Choosing the point table using DI0 to DI2 and turning ST1 ON starts a motion in the forward rotation
direction over the travel distance of the position data (target position) at the preset speed and
acceleration time constant.
Turning ST2 ON starts a motion in the reverse rotation direction according to the values set to the
selected point table.

Note 1. Reverse rotation start (ST2) is invalid in the absolute value command system.
2. 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.
3. 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.
