B- 5 V
Z+ 15 V
Z- 24 V
• 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).
