SYSTEM ALARM and WARNING
MOT
4050:SPINDLE ORITENTATION SIGNAL NOT FOUND
Assumed the spindle has rotated one time already but it hasn’t found the orientation
position sensor while executing machine adjustment or while orientation program is
running. The following alarm messages will occur.
(1)Checking whether or not there is connection problem on the spindle orientation
sensor
(2)Checking whether or not the spindle orientation sensor signal and type setting is
correct (Parameter # 184).
(3)Checking whether or not the spindle orientation sensor is broken.
MOT 4051:NO SPINDLE SPEED DEFINE
No spindle speed definition. So please define rotary command in rigid tapping. Please
key-in rotational speed command S before tapping command.
MOT 4052:MOVE ERR OVER LIMIT IN RIGTAP
(1)Please check whether or not the procedure of rigid machine adjustment is
completed.
(2)Please check whether not the setting value of Parameter 1058 is too small.
MOT 4053:SPD SPEED WILL OVER LIMIT
(1)Please check whether or not the setting spindle rotational speed is over the
maximum speed that this gear spindle can handle.
(2)Please check whether or not the setting of Parameter NO. 1060 for the spindle
return accelerating speed is too big under rigid tapping. Unless necessary,
recommend setting to 100.
MOT 4054:Z AXIS FEEDRATE WILL OVER LIMIT
Z axis cutting feedrate speed of rigid tapping is larger than the maximum cutting
speed that is set by Parameter 1004.
(1) Checking whether or not Parameter NO. 1060 has set the spindle returning
accelerating speed too large under rigid tapping. If speed starts to accelerate
while returning (i.e., P1060 > 1000), then speed of cutting spindle will
accelerate too. Unless necessary, recommend to set 100.
