10-9 Multi Signal Errors [A.10 - *]
• Code A10-01 – SEQUENCE SELECT ERROR
System detected that the sequence number selected by the PLC is invalid when the start signal or
manual reverse signal was applied.
RECOVERY:
1. Check the sequence number selected by the PLC. The System uses two different ways of
selecting the sequence number:
a. Binary Input.
If the "USE INDIVIDUAL SEQUENCE SELECT" bit (bit 11) is turned off, the system
uses the combination of SEQUENCE SELECT BIT 0 ~ 4 for selecting sequence
program between 1 ~ 32.
b. Individual Sequence Select Input.
If the "USE INDIVIDUAL SEQUENCE SELECT" bit (bit 11) is turned on, the system
uses individual sequence select signals (bit 16 ~ 47) for selecting sequence program
1 ~ 32.
If none of these bits are turned on or more than two bits are turned on when
the start signal or manual reverse signal is turned on, this error will occur.
• Code A10-02 – SPINDLE NOT FOUND ERROR
• The system received a START signal or Manual REVERSE signal while the Axis Link cable was
disconnected.
• The system did not receive a reply from the spindle (Axis) specified in the sequence program
when the system started a fastening cycle.
RECOVERY:
1. Check the communication cable between spindles.
2. Make sure all connected spindles can be found during a spindle search in the AFC3000 User
Console Software.
3. Confirm Ready status in the PLC for all connected spindles before issuing a START or Manual
REVERSE.
• Code A10-03 – SEQUENCE ERROR
The System lost communication with the spindle (axis) during the fastening cycle.
RECOVERY:
1. Check the communication cable(s) between spindles are connected.
2. Confirm the Axis Link terminators are installed in the first and last spindles on the link. (See 3-16)
