4.9. Feedback and Analog Input
The Gold Solo Trombone has two configurable motion sensor input ports: Port A and Port B,
and one emulated buffered output port: Port C. Motion sensors from the controlled motor and
from other sources can be connected to any of the available inputs on either port A or B.
Software configuration designates each input a role, e.g., the incremental encoder on port B is
the controlled motor position feedback, the Hall sensors on port A are commutation feedback,
and the incremental encoder on port A is follower input.
For more information about sensors and their use refer to the Gold Line Software Manual.
4.9.1.
Feedback Port A
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 & 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.
A cable kit containing a cable that connects to port A is available. See Section 5.1.11.
