J3 –1
SFD +5 V
This terminal provides a 5 VDC output to power the feedback device. For
example, motor equipped with SFD, Halls or commutation encoder.
The load current should not exceed 200 mA.
J3-2
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.
J3-3
SFD COM-
SFD serial communications port when using the SFD feedback device.
No connection when using Hall feedback.
J3-4
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 k
Ω
pull-up resistor to 3.3 volts.
J3-5
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 k
Ω
pull-up resistor to 3.3 volts.
J3-6
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 k
Ω
pull-up resistor to 3.3 volts.
Shell
Outer shield connection (wired to PE in the drive).
