The fan is rotating, and an alarm did
not occur again.
Continue to use.
The power may be turned ON without
assuring more than 10 seconds for
the time from when the power is
turned OFF till when it is turned ON.
Leave for more than 10 seconds or
more, and turn the power ON again.
1 Turn the unit power ON again, and
confirm the rotation of the fan.
Note) Assure more than 10 seconds
for the time from when the
power is turned OFF till when it
is turned ON. For the fan used
for the drive unit, assuring
more than 10 seconds for the
time from when the power is
turned OFF till when it is turned
ON is required.
The fan did not rotate. Or, an alarm
occurred again.
Investigate item 2.
{ {
Large amounts of cutting oil or cutting
chips, etc., are adhered, or the
rotation is slow.
Clean or replace the fan. 2 Confirm adhesion of cutting oil or
cutting chips, etc. at the fan. Or check
