144 Time-out- Call Your Dealer Time allocated for use prior to payment exceeded. Call your
dealer.
145 X Limit Switch Axis hit limit switch or switch disconnected. This is not normally
possible as the stored stroke limits will stop the slides before
they hit the limit switches. Check the wiring to the limit switches
and connector P5 at the side of the main cabinet. Can also
be caused by a loose encoder shaft at the back of the motor or
coupling of motor to the screw.
146 Y Limit Switch Same as alarm 145
147 Z Limit Switch Same as alarm 145
148 A Limit Switch Normally disabled for rotary axis.
149 Spindle Turning Spindle not at zero speed for tool change. A signal from spindle
drive indicating that the spindle drive is stopped is not present
while a tool change operation is going on.
150 Z and Tool Interlocked Changer not at home and either the Z or A or B axis (or any
combination) is not at zero. If RESET, E-STOP, or POWER OFF
occurs during tool change, Z-axis motion and tool changer
motion may not be safe. Check the position of the tool changer
and remove the tool if possible. Re-initialize with the AUTO ALL
AXES button but be sure that the pocket facing the spindle
afterwards does not contain a tool.
151 Low Thru Spindle Coolant For machines with Through the Spindle Coolant only. This alarm
will shut off the spindle, feed, and pump all at once. It will turn on
purge, wait for the amount of time specified in parameter 237 for
the coolant to purge, and then turn off the purge. Check for low
coolant tank level, any filter or intake strainer clogging, or for any
kinked or clogged coolant lines. If no problems are found with
any of these, and none of the coolant lines are clogged or kinked,
call your dealer.
152 Self Test Fail Control has detected an electronics fault. All motors and
solenoids are shut down. This is most likely caused by a fault of
the processor board stack at the top left of the control. Call your
dealer.
153 X-axis Z Ch Missing Broken wires or encoder contamination. All servos are turned off.
This can also be caused by loose encoder connectors.
154 Y-axis Z Ch Missing Same as alarm 153.
155 Z-axis Z Ch Missing Same as alarm 153.
156 A-axis Z Ch Missing Same as alarm 153.
