•
Code A10-8 – MOTOR POWER LOSS DETECTED
The system has detected the loss of motor power (3 phase) in the spindle selected by the sequence
program during the fastening sequence or manual reverse operation
RECOVERY:
1. Check the 3 phase motor power input for all spindles (Voltage between 200 – 230VAC)
2. Confirm capacity of motor power supply transformer (power is not dropping during cycle)
•
Code A10-9 – AXIS LINK COMMUNICATION ERROR
A Communication error has been detected on the Axis Communication link.
RECOVERY:
1. Check the communication cable(s) between spindles.
2. Confirm the Axis Link Terminators are in place on first and last spindles
3. Confirm all spindles have the same version firmware
4. Check that all consecutive spindle numbers are set correctly (DIP Switch) and there is no overlap
5. Skip a controller from the Axis Link (one at a time) to determine which controller is causing the
communication error (Replace the suspect controller)
•
Code A10-10 – SEQUENCE STEP CHECK ERROR
•
System detected incorrect sequence command was performed in one of the (connected) spindle
controllers (Spindle is out of sequence)
•
With a Master controller (ver. 1.400 or later) with this function enabled, if a controller with a firmware
version that does not support this function (before version 1.400) which is mixed in the connected
spindles, will generate this abnormal. (In this case, see #3 below)
RECOVERY:
1. Check the communication cable(s) between spindles.
2. Confirm the Axis Link Terminators are in place on first and last spindles
3. Confirm all spindles firmware version are 1.400 or higher
Note : If earlier version than 1.400 is mixed in the system, disable the ‘Sequence Step Check’ feature
(temporarily) by turning ON DIP switch SW2-5 . This will disable this check until the firmware can be
updated on the (old version) controller(s). Contact FEC Inc. for updating the firmware.
4. Check that all consecutive spindle numbers are set correctly (Spindle number Rotary Switch) and
there is no overlap
5. Skip a controller from the Axis Link connection (one at a time) to determine which controller is
causing the communication error (Replace the suspect controller)
6. Check that motor cables do not exceed maximum length (100feet) (shorten cables or add noise
protect if necessary)
7. Check that controller power cables do not exceed (30feet) (shorten cable(s) or add noise protect if
necessary)
8. Replace controller with spare
