2.2.7. Feedback Ports Options
• There are Port A and Port B feedback input ports that are flexible and configurable. Each
port can be programmed to serve as:
 Commutation feedback and/or
 Velocity feedback and/or
 Position feedback
• Port A supports the following sensors, depending on the specific model:
 Incremental encoder
 Incremental encoder and digital Hall
 Absolute serial encoder
 Absolute serial encoder and digital Hall (for dual loop)
• Port B supports the following sensors, depending on the specific model:
 Incremental encoder
 Analog encoder
 Analog Hall
 Resolver
• Port C is a flexible and configurable feedback output port. It supports the Encoder
emulation outputs of Port A or Port B or internal variables
• Analog input (±10 V ptp) support:
 Velocity feedback (Tachometer)
 Position feedback (Potentiometer)
2.2.8. Feedback Sensor Specifications
