1 STEP The function of this key is the same as the 1 STEP ADVANCE
REVERSE key except the steps are reversed.
If the E-STOP button is pressed while the shifter is moving, the shifter retraction position signal
is turned off. This sometimes renders the APC operation keys inoperative. If so, press the 1
STEP ADVANCE key while pressing the INTERLOCK RELEASE key. This should advance
the automatic pallet change cycle one step at a time.
When the RUN status lamp is on, the ATC/APC operation keys mentioned above are inopera-
tive. Press the RESET key to turn off the RUN lamp. In other words, these keys are ineffective
when the control is in AUTO or MDI operation mode.
Pendant Operation Panel
The pendant operation panel will differ from machine to machine. These types of panels are
mostly used on double column machining centers. Most of the switches on this type of panel are
the same as the switches on the Machine Operation panel. For a description of the switches on
this panel, please refer to the Operation manual of the machine in question.
Optional Panel
This panel is for switches and lamps related to the optional functions that can be purchased with
the machine. An example of an option panel would be a panel for Auto door open/close and the
Touchsetter option.
On machining centers the Power ON and OFF buttons are located on an option panel located on
the control cabinet door. The following is a description of the controls that are on this option
panel. A picture of this panel can be seen on page 4-35.
Puncher
SERIAL This is the RS-232C interface connector. This interface connector is
called the CN0 port and is now standard.
PARALLEL This is the parallel port interface.
AC 100V 2A This is the power receptacle for the Paper tape puncher.
HOUR METER
The first hour meter with the lightening symbol is the power on time meter. It accumulates the
amount of time the machine has been on.
The second hour meter is the NC Running Time meter. It accumulates the length of time the
RUN lamp on the NC operation panel is on.
Operation End Mode
BUZZER This is the Operation End Buzzer activation switch. If this switch is on,
the buzzer will sound at the end of a program run. The length of time it
sounds is set by MC user parameter word No. 7.
LIGHT This is the Operation End Light activation switch. If this switch is on, the
YELLOW light on the pendant arm will come on when an end of program
code is read.
