[Pr. PC19.1_Encoder output pulse setting selection]
Initial value
0h
When an encoder other than an A/B/Z-phase differential output type encoder is connected, setting this servo parameter to "4"
causes [AL. 037 Parameter error] to occur.
0: Output pulse setting
1: Dividing ratio setting
2: The same output pulse setting as the command pulse
3: A-phase/B-phase pulse electronic gear setting
4: A/B-phase pulse through output setting
