S200: J3
Feedback Connector

 

J3 is a 6-pin pluggable IEEE 1394 style connector for the feedback device. Although this connector mechanically accepts standard IEEE 1394 cables, it is electrically not an 1394 interface. The base drive accepts either SFD (Smart Feedback Device) or Hall inputs.

Signal Descriptions

SFD +5 V
This terminal provides a 5 VDC output to power the feedback device. For example, motors equipped with SFD, Halls or a commutation encoder. The load current should not exceed 200 mA.

SFD +5 RTN
This terminal is the return connection for the 5 VDC supply. An inner feedback cable shield can be connected to this point. Outer shields should connect to the shell which is PE.

SFD COM
SFD serial communications port when using the SFD feedback device. No connection when using Hall feedback.

SFD COM+ / CU
SFD serial communications port when using the SFD feedback device. CU (Commutation Phase U) input when using open collector Hall feedback. This input has a 2.21 kW pull-up resistor to 3.3 V.

NC / CV
No connection when using the SFD feedback device. CV (Commutation Phase V) input when using open collector Hall feedback. This input has a 2.21 kW pull-up resistor to 3.3 V.

NC / CW
No connection when using the SFD feedback device. CW (Commutation Phase W) input when using open collector Hall feedback. This input has a 2.21 kW pull-up resistor to 3.3 V.

Shell
Outer shield connection (wired to PE in the drive).
