Causes
Communication between the feedback scale and the
driver has been interrupted in certain times, and
disconnection detecting function has been triggered.
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.
Bit 0 of the feedback scale error code (ALMC) has been
turned to 1.
Check the specifications of the feedback scale.
Bit 1 of the feedback scale error code (ALMC) has been
turned to 1.
Check the specifications of the feedback scale.
Bit 2 of the feedback scale error code (ALMC) has been
turned to 1.
Check the specifications of the feedback scale.
Bit 3 of the feedback scale error code (ALMC) has been
turned to 1.
Check the specifications of the feedback scale.
Bit 4 of the feedback scale error code (ALMC) has been
turned to 1.
Check the specifications of the feedback scale.
Bit 5 of the feedback scale error code (ALMC) has been
turned to 1.
Check the specifications of the feedback scale.
A-phase wiring in the feedback scale is defective, e.g.
discontinued.
B-phase wiring in the feedback scale is defective, e.g.
discontinued.
Z-phase wiring in the feedback scale is defective, e.g.
discontinued.
There is an error in CS signal logic.
(All of CS signals 1, 2, and 3 are high or low)
There are extremely few AB-phase pulses between CS
signal changes.

Measures
• 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".
• 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
After removing the cause of the error, clear the feedback scale
error.
And then, shut off the power to reset.
Check the A-phase wiring connection of feedback scale scale.
Check the B-phase wiring connection of feedback scale scale.
Check the Z-phase wiring connection of feedback scale scale.
Check the CS signal wiring connection.
Check the CS signal, A-phase, and B-phase wiring
connections.
