Meaning
There was a request that was incompatible
with the connected encoder.
Examples:
• An Absolute Encoder Reset (ABSPGRES
command) was requested when an incre-
mental encoder is connected.
• Homing start was requested (/HOME sig-
nal was turned ON or ZRN command was
executed) when an absolute encoder is
connected.
(An absolute encoder can be used as an
incremental encoder if parameter
Pn002.2 = 1.)
A Multi-turn Limit Setting (MLTLIMSET
command) was requested even though
alarm A.CC0 has not occurred.
(Alarm A.CC0 indicates that Pn205 does
not match the setting in the encoder after
the multi-turn limit setting in Pn205 was
changed and the control power supply was
turned OFF and ON.)
An attempt was made to execute a continu-
ous stop under conditions where it could
not be executed.
Examples:
• The coordinates have been set to linear
moving method.
• The immediately-preceding table target
position is not ±INFINITE.
• The immediately-preceding table target
position is ±INFINITE, but the registration
distance is set.
• A value other than 1 has been set for the
execution count.
Continued from previous page.
Corrective Action
Check the
encoder.
Use the Multi-
turn Limit Setting
operation to
adjust the setting
in the encoder to
match Pn205
only after alarm
A.CC0 has
occurred.
Execute a contin-
uous stop under
conditions where
it can be exe-
cuted.
