TTL signal types

Setting Function Example
AF_B (0)
  • TTL signals (track A, track B)
  • Direction of rotation of "slave axis" equal to "master axis"
AR_B (1)
  • TTL signals (track A, track B)
  • Direction of rotation of "slave axis" in inverse proportion to "master axis"
ABDFN (2)
  • Pulse-direction signals (track A: pulse; track B: direction)
  • With a rising edge of track B positive direction
  • Only falling edges of track A are evaluated.
ABDRP (3)
  • Pulse-direction signals (track A: pulse; track B: direction)
  • With a falling edge of track B negative direction
  • Only rising edges of track A are evaluated.
