The explanation assumes that the input waveform has been set to the negative logic and forward and
reverse rotation pulse trains (parameter No. PA13 has been set to 0010).
The waveforms of PP, PG, NP and NG are based on that of the ground of the differential line driver.

(2) In-position (INP)
PF-SG are connected when the number of droop pulses in the deviation counter falls within the preset in-
position range (parameter No. PA16). INP turns on when low-speed operation is performed with a large
value set as the in-position range.
