A 1 A A+ • Max. signal frequency: 200 kHz
• Signal levels:
• Decision levels are automatically defined based
on the daisy chained power supply voltage level.
• Input channels are isolated from the logic and
ground.
• When the drive runs in the Forward direction,
channel A should lead channel B by 90°
(electrical).
• Channel Z: One pulse per revolution (used in
positioning applications only).
