M11 Installation, Maintenance, Service, & Part List Manual

128 - ATC ERROR - The ATC was commanded to home but it's not in the back

position. Manually move the ATC all the way back and then re-home the machine

. -

If the ATC is back, then the limit switch probably has moved or failed. Check the light on the
switch and the LED on the back of the control. Use the Hardware Tester application to confirm

the proper inputs. This message happens during homing.

129 - ATC ERROR - The ATC was commanded to move but its position is not known.

Check that air pressure is available and ATC limit switches are functioning properly

. -

The ATC loses air pressure, 24 volts or is not on the limit switch when the machine is disabled, it

needs to be pushed back and servos re-enabled. Even a very short loss air pressure may cause

this condition. The ATC must be "homed" the first time after power-up when the axes are

homed. The ATC must be on the back limit switch, air pressure and 24 volts must be available,

then the door must be closed and the GO button pressed (to initiate homing).

131 - ATC ERROR - The ATC timed-out moving to the front. Check and make sure that

there is no access of chips accumulated between the ATC and the back of the table,

that air pressure is available, and that the ATC limit switches are functioning

properly

. - When moving forward, the ATC never detected the front limit switch. Check the

light on the switch and the LED on the back of the control. Use the Hardware Tester application
to confirm the proper inputs.

132 - ATC ERROR - The ATC was commanded to the back position, but the back limit

switch is not active. Check the limit switches

. - If the ATC is back then the limit switch

probably has moved or failed. Check the light on the switch and the LED on the back of the
control. This error message may occur during tool changes and tool loading/unloading.

139 - ATC ERROR - The ATC carrier is trying to move but the air pressure is too

low. Check air pressure and make sure it is set to the correct amount

. - If the ATC is

commanded to move but pressure was not available (for even a short time) this message may
occur. Often times, during a tool change, the Tool Unclamp (draw-bar) actuator is activate to

release the tool. If the air pressure is set below 65 PSI, this large sudden use of air may cause

this ATC problem. Check that the air pressure regulator lower limit is properly adjusted and that

the shop air supply is sufficiently high and has enough volume to not cause a momentary drop in

air pressure. Also, check and make sure that the air filter is not plugged up, if it looks dirty, it

may require cleaning or replacement.

208 - ATC ERROR - ATC limit switch failure. Both the front and the back switches are

active at the same time

. The ATC location is unknown. Check that both limit switches are

functioning properly. - During normal operation both switches should not be active. Check the
lights on the switches and the LEDs on the back of the control. Use the Hardware Tester

application to confirm the proper inputs.

216 - TOOL CLAMP ERROR - The tool clamp was actuated, but no air pressure is

available. Check air pressure

. - Check that the air pressure regulator is properly adjusted and

that the shop air supply is sufficiently high and has enough air flow to not cause a momentary

drop in air pressure. If the air supply pressure is Ok, check the air filter and make sure it is not

excessively dirty.

217 - TOOL CLAMP ERROR - Both tool clamp and unclamp limit switches are active at
the same time

. Check that both limit switches are functioning properly. - During normal

operation both switches should not be active. Check the LEDs on the back of the control. Use

the Hardware Tester application to confirm the proper inputs.
