56 Internal fan stopped If the internal fan stops, the warning signal
is output. Since the spindle continues to
operate at this time, use the PMC to per-
form processing as needed.
About one minute after the warning signal
is output, an alarm occurs.
88 Radiator cooling fan
stopped
If the radiator cooling fan stops, the warn-
ing signal is output. Since the spindle
continues to operate at this time, use the
PMC to perform processing as needed.
If the main circuit overheats, an alarm oc-
curs.
04 Open–phase de-
tected in the con-
verter main power
supply
If an open–phase is detected in the main
power supply, the warning signal is output.
Since the spindle continues to operate at
this time, use the PMC to perform proces-
sing as needed.
About one minute (for the PSM) or about
five seconds (for the PSMR) after the
warning signal is output, an alarm occurs.
58 Converter main cir-
cuit overloaded
If the main circuit of the PSM is over-
loaded, the warning signal is output.
Since the spindle continues to operate at
this time, use the PMC to perform proces-
sing as needed.
About one minute after the warning signal
is output, an alarm occurs.

17.6 Warning Interface for the αi Spindle
For the αi spindle, the warning state can be reported before an alarm is
issued. When the warning state is entered, a report to the PMC is sent.
For example, this signal can be used for retracting tools or reducing cutting
load from the time a warning occurs by the time an overheat alarm occurs.
In addition, diagnostic information also contains warning numbers.

SPWRN1 to 9 <IF2113 to +7 , IF2121 >
[Classification] Output
[Function] Reports the warning number corresponding to the
state of the αi spindle amplifier.
[Output condition] When the αi spindle is in the warning state, a
warning number consisting of SPWRN1 to SPWRN9
is output as nine–bit binary data.
If warnings occurred on multiple αi spindle
amplifiers, the warning number of the αi spindle
having the smallest axis number is output.
However, when there is no αi spindle or the system
configuration of the spindle includes an additional
spindle that is older than the αi spindle, this function
is invalid for all spindles.
The warning numbers and their descriptions are
shown below.
