Feedback scale
wiring error
protection
(Not supported)
Communication between the feedback scale and the
driver has been interrupted in certain times, and
disconnection detecting function has been triggered.
• Make a wiring connection of the feedback scale as per the
wiring diagram.
• Correct the miswiring of the connector pins.
• Check to see if the feedback scale type (AB-phase, serial
incremental, serial absolute) coincides with Pr 3.23
“Feedback scale type selection”.

Feedback scale
communication
data error
protection
Communication error has occurred in data from the
feedback scale. Mainly data error due to noise. Feedback
scale cables are connected, but communication date has
some error.
• Secure the power supply for the feedback scale of 5 VDC
±5% (4.75 to 5.25 V)...pay attention especially when the
feedback scale cables are long.
• Separate the feedback scale cable and the motor cable if
they are bound together.
• Connect the shield to FG...refer to wiring diagram of
external scale in Reference specication SX-DSV02828

CS signal logic
error
protection
There is an error in CS signal logic.
(All of CS signals 1, 2, and 3 are high or low)
Check the CS signal wiring connection.

AB-phase missing
error
protection
There are extremely few AB-phase pulses between CS
signal changes.
Check the CS signal, A-phase, and B-phase wiring
connections.
