• If Autotuning Does Not End
Failure of autotuning to end
, is caused by an inappropriate machine rigid-
ity setting. Follow the procedure below to correct the machine rigidity setting, and run
autotuning once more.
(1) Press the
DSPL
SET
(or
MODE/SET
) key to cancel autotuning.
(2) Press the
DSPL
SET
(or
MODE/SET
) key once more to enter the machine rigidity setting
mode. Increase the setting by one.
Autotuning may not end for machines with large play or extremely low rigidity.
In these cases, use conventional manual adjustment.
c) Input Signals
• The OT signal and SEN signal (absolute encoder only) are enabled during autotuning.
Input the OT signal and SEN signal (absolute encoder only) during autotuning.
To conduct autotuning without inputting these signals, set user constant Cn-01 Bits 1,
2, and 3 to 1.
• Autotuning is not possible during overtravel
(P-OT or N-OT signal OFF).
• Conduct autotuning when no overtra-
vel has occurred (both P-OT and
N-OT signal ON).
• Set the P-CON
signal OFF during autotuning.
