Understanding Feedback
Specifications
The 1394 SERCOS interface system module can accept motor feedback
signals from the following types of encoders:
• Stegmann Hiperface
• Resolver Transmitter TR = 0.25
• TTL AQB or Sine/Cosine (Feedback Only axis configuration in
RSLogix 5000)
The 1394 SERCOS interface system module can accept auxiliary
feedback signals from the following types of encoders:
• Stegmann Hiperface
• TTL AQB or Sine/Cosine with index pulse
Note: Auto-configuration in RSLogix 5000 software of intelligent
absolute or high-resolution is possible only with Allen-Bradley
motors.
