In-position (INP)
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 program 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.
