The table provides a description of the AM and BM inputs for Sine/Cosine
encoders.

Auxiliary Feedback (AF)
These requirements apply to the Auxiliary Feedback signals.
• For TTL devices, the position count increases when A leads B.
• For sinusoidal devices, the position count increases when cosine leads sine.
• TTL devices must be 5V devices within the input voltage specification.
• Use the Low Profile Connector Kit, catalog number 2090-K6CK-D15F to
access the Auxiliary Feedback signals. You must supply cabling that has
shielding, and other EMI protection for motor feedback cables.
IM Pulse Width Pulse width of the index input signal. Since the index
is active for a percentage of a revolution, the speed
determines the pulse width.
