<5> Pressing the [TP CAL] soft key causes a full-screen touch panel calibration screen to appear.

<6> Click the 9 calibration points with a stylus pen. The marker of a normally clicked point changes

from "+" to "o". If you fail to click right on a "+" mark, the message "Your stylus pen is not right on

a "+" mark. Click again." appears.

<7> After clicking all 9 calibration points, clicking the

key completes calibration. To quit or retry

calibration, click the

key. The previous screen appears again. Before clicking 9 calibration

points, clicking the

key aborts calibration.

<8> When calibration ends normally, the message "Calibration ended" appears.

<9> After completing calibration, disable the touch panel calibration screen (by resetting the DCL

parameter (bit 5 of parameter No. 3113) to 0) to prevent operation mistake.

3.15 REPLACING THE BACKUP UNIT

When "NCBOOT32- A battery backup hardware alarm(04E5)" appears on the screen of the

personalcomputer function with Windows^® CE, replace the backup unit.

Procedure

<1> Turn off the CNC power, replace the backup unit, and turn on the power again.

<2> When the Windows screen appears, press the Ctrl key and Aux key of the MDI in sequence to

display the start menu, and start Windows Explorer.

<3> Execute "Storage Card¥Fanuc¥NCBOOT32.exe".

<4> When a pop-up menu appears at the lower left of the screen, select "Open".

<5> Check "Enable battery backup unit" to enable backup operation.

<6> Select "OK" to close NCBOOT32.

<7> Execute "Storage Card¥Fanuc¥NCBOOT32.exe".

<8> When a pop-up menu appears at the lower left of the screen, select "Save".

<9> Turn off the CNC power and back on again. Confirm that a backup operates normally and no alarm

appears.

CAUTIONS COMMON TO THE OTHER UNITS

Replacing fuses

WARNING

Before replacement of a blown fuse, the cause of the blown fuse must be

corrected. So, fuse replacement work must be done only by a person who is

trained in the related maintenance and safety requirements. When opening the

cabinet and replacing a fuse inside, be careful not to touch the high-voltage

circuits (marked with

and fitted with an insulating cover). Touching the

uncovered high-voltage circuits presents an extremely dangerous electric shock

hazard.

See the descriptions of each unit in this chapter for the locations of their fuses.

See also Appendix B, “LISTS OF UNITS, PRINTED CIRCUIT BOARDS, AND CONSUMABLES” for

the specifications of the fuses for each unit.

4.2

UNITS SUPPORTING I/O Link i

4.2.1

Items Common to Units Supporting I/O Link i

- Meanings of LED displays on units supporting I/O Link i

The standard I/O Link i incorporates three LEDs, “LINK” (green), “ALM” (red), and “FUSE” (red) for

each unit separately. The information represented using each LED is as follows:

LED「LINK」(green)

Indicates the status of communication by the unit of interest.

LED「ALM」(red) Indicates that an alarm has been issued in the unit of interest.

LED「FUSE」(red)

Indicates where there is a blown fuse in the unit of interest.

See Section 10.26 for descriptions of the on/off states of the LEDs and their meanings.

- Status Alarm

Some I/O units have a function which detects unit errors including DO alarms (ground faults) and DO

common voltage errors. If these units detect an error described above, how detected information is

transferred to the master differs between the I/O Link and I/O Link i.

With the I/O Link, detected information is transferred to the master as DI signals. For this reason, to allow

the master to reference the detected information, as many signals as required for the detected information

must be assigned to X addresses. As many signals as required for the detected information are assumed as

the number of DI signals used by the group and channel.

With the I/O Link i, detected information is called a status alarm, and the CNC is notified of the status

alarm separate from DI signals. For this reason, it is not necessary to assign the information to X

addresses. If an error occurs, the information is output to the system relay (R or Z) area. The information

only for one group per channel is output to the system relay area. Only the information for the first group

in which a status alarm is detected is output.

Given below are the examples of system relay areas where a status alarm is issued.

See the descriptions of each unit in this section for the correspondence between the slot number and alarm

information number for them.

4.MAINTENANCE OF THE OTHER UNITS

B-64485EN/01

CAUTION

2 Disconnection detection is performed by monitoring, with an output element in the

module, the current flowing through a load when DO output is ON. When the

detected current value is about 100 mA or less, disconnection detection is

assumed. So, when a device (such as an LED) with a small load current is

connected, the DO alarm state results, assuming disconnection detection. Unlike

the other protection functions, however, this function does not turn off DO output.

If a connection is reactivated after the state of disconnection is once set,

disconnection detection is canceled without restarting the system.

Rotary switch

CAUTION

When replacing extension modules, set the rotary switch on a replacing module in

the same manner as for the replaced module.

Re-setting the rotary switch on each extension module can be used to connect them by skipping other

modules. For details, see descriptions of the rotary switch in Subsection 4.2.2, “I/O module for connector

4.MAINTENANCE OF THE OTHER UNITS

NOTE

In the protected mode, the lowest address number among those encountering a

configuration mismatch is displayed. In the configuration mode, nothing is

displayed.

Use ladder programs to detect and display converter unit errors.

If a converter unit error occurs, both the DO and DI are turned off.

If it is impossible to continue AS-i communication, a watchdog alarm condition

occurs in the slave unit. How the DO behaves at the watchdog alarm is

determined according to the slave unit type and parameter setting used. See

the relevant slave unit specification.

How to handle AS-i master EEPROM errors

If the 7-segment LEDs display "E1", it is likely that the registered configuration

may be corrupted. So, register it again according to the following chart.

Turn off power

Place switch in SET position, and turn on power again.

7-segment LED displays "E1" (keep switch in SET position).

Keep switch in SET position until LED "CM" changes from off to on or from on to off.

(This operation may take 5 seconds or more.)

Take your hand off switch, and turn power off and on again to restart system.

If 7-segment LEDs do not display "E1", registered configuration has been repaired.

(If LED "CM" lights, protect registered configuration for subsequent operation. Keep switch in SET position

until "E1" disappears. This operation takes 5 seconds or more.)

If 7-segment LEDs still display "E1", replace converter unit.

Note that if "E1" is displayed, the CNC may fail to start up.

The converter having this function is one shipped in or after June 2005.

Those shipped before do not support this function. If EEPROM fails to operate

normally, replace the converter unit.

How to re-install

Once the I/O Link - AS-i converter is replaced, the new I/O Link - AS-i must be loaded with AS-i slave information

according to the following procedure.

The procedure can be executed even when no I/O Link is connected (when power is supplied to the I/O Link - AS-i

converter but not to the CNC or when no I/O Link cable is attached).

Operating procedure for AS-i slave replacement

Described below is the operating procedure for AS-i slave replacement (in case the slave is faulty). It is necessary

to set a slave address, using either of the following two:

(1) Commercially available address setting device.

(2) Automatic address setting function of the I/O Link-AS-i converter; how to use the function is explained below.
