4.9.1. Port A (J2)
Port A supports the following sensor inputs:
• Digital Hall sensors
• Incremental encoder or absolute serial encoder, depending on the specific model
Differential pulse-width modulation (PWM) signal input can be connected to port A in the
models that support input from an incremental encoder. The PWM signal can be connected to
the applicable pair of matching + and – encoder channels and is configurable by software.
Differential pulse and direction signal inputs can be connected to port A in the models that
support input from an incremental encoder. The signals can be connected to the applicable pair
of matching + and – encoder channels and are configurable by software.
