OVERVIEW

This chapter outlines the features of the EV

1

Counter for linear gages.

1.1 EV Counter

1.1.1 Features

• Three models of EV counter (EV-16P, EV-16D, and EV-16Z) are

available according to the linear gage connected. The applicable
gages for each model are as follows.
EV-16P: LGF, LGB, and LGE series linear gage (excluding the mod­els that output sine waves)
EV-16D: LGD and LGS series linear gage
EV-16Z: LGF-Z series linear gage

• EV counter is a multi-axis counter to which plural gages can be con-

nected. The maximum number of gages that each model can connect
is 6.
Only EV-16Z supports the origin embedded gages.

• The origin function of EV-16Z realizes high-speed response and re-

duces the time and labor taken by referencing with a master each time
the power is turned on.

• With the RS LINK function a maximum of ten EV Counter units can

be linked. This makes it possible to construct a system consisting of a
maximum of sixty linear gages through one RS-232C port, which is
on, for example, a personal computer.

• The display unit is of a separate type (optional) which takes in-line

use into consideration.

• Depending on the external devices to be connected and uses, the fol-

lowing I/F connection and output mode can be selected:

[Connection I/F]

Tolerance judgment output

Separately outputs the judgment result from each CEL.

Segment output

Outputs the range specified by the external signal after evenly di­viding it into ± ten stages.
The objective CEL to be output and its range can be specified with
the external SET signal.

BCD output

Output of sign and 6-digit data.
The objective CEL to be output can be designated with the external
SET signal.

RS-232C/RS LINK

A maximum of 10units/60 channels can be linked.
Preset and tolerance values can be remotely controlled.
Can be used simultaneously with other I/O devices.

[Output mode]

NORMAL mode (factory-set default)

Calculation mode

Calculate the sum, mean, maximum, minimum, and width be­tween the specified CELs and outputs the results.

High-speed mode

Quickly outputs the specified CEL.

c) Precautions in using the EV-16Z

If the EV-16Z is used, note the following precautions.

IMPORTANT Be sure to pass the spindle through the origin for

detection properly. If the spindle vibrates near the
origin, the origin may not be detected correctly.

TIP • The origin-embedded gage has a specific origin in-

side the gage. When the spindle passes through the
origin the signal generates, then the preset position is
restored.

• Origin detection is usually performed when the power
is turned on. If the origin re-detection parameter
(P.No.42) is set to 1, the counter enters the origin de­tection wait mode after completing preset or tolerance
setup (for details, refer to the section, “3.1 Setting
Parameters (with D-EV)”), or when the HOLD signal
is triggered.

• If the HOLD signal is input again during origin re-de­tection, the counter resets origin re-detection, except
when resetting an error.

TIP Relationship between the parameter setup values and

available axes
An EV Counter has six internal counters (CEL 1 - 6).
Data of gages connected to the gage input connectors,
INPUT A - F, will be displayed/output as the data of CEL
1 - 6, respectively.
Available axes are designated by determining the rela­tionship between INPUT A - F and CEL 1 - 6. The follow­ing table lists the possible combinations.

: If the setup value is "2", internal counters CEL1, 3, and 5 will
display/output the data of INPUT A. Internal counters CEL2, 4,
and 6 will display/output the data of INPUT B. By setting a differ­ent tolerance value for each of CEL1, 3, and 5, three different
types of tolerance judgments can be made from the data of IN­PUT A.
*2 : The factory-set default is "6".

3.1.4 Parameter mode OFF

(1) Press the P.SET key while holding down the Fn key to set

the parameter mode to OFF. If the EV-16Z is used, push in
the spindle to pass through the origin. The parameter setup
is modified and the Display Unit returns to the count value
display.

NOTE • If the P.SET key is pressed during the setup operation

and while the Fn key is being held down, the setup
operation is interrupted and the count value display is
restored. (If the EV-16Z is used, push in the spindle to
pass through the origin.) If this occurs, the modifica­tions made up to the interruption are reflected in ac­tual operation.

• During parameter setup operation, the parameter in-

put switch, RS-232C output, and external signal input
are all disabled.

3.2 Setting Parameters (with EV Counter)

Before using the EV Counter, various parameters must be set
up. The parameter setup operation is easily performed if a D­EV is used.

IMPORTANT The EV-16Z can not modify the origin-related set-

tings by itself. For making this modification in EV­16Z, prepare a D-EV.

NOTE • Use a D-EV for the resolution of 0.1µm setting.

Set up of EV Counter alone, is not possible.

• Only a D-EV allows setting when the modification is
made for the parameter no.41, 42, and 43.

• In order to connect a gage with a resolution that is not
1µm, the counter must modify its resolution setting to
that of the connected gage if the EV-16P or EV-16Z is
used.

• The gage type (INC, ABS, etc.) must be set for the
EV-16D.

• If the setup is made as (Number of available axes) >
(Number of gages), an error display/output (Error40)
will result.
If the setup is made as (Number of available axes) <
(Number of gages), gages that are not designated will
be ignored. For information refer to section 8.4 List of
Error Outputs.

4.2 Switching the Display/Output CH (with D-EV)

Use the DISP key to switch the display/output CH (channel).
This section explains the procedure, using the top EV Counter
connected via the RS LINK function as an example.

(1) When the counter enters the counting mode after the power

is turned on, the count value of CH01 (CEL1) is displayed
on the D-EV, and the corresponding GAGE No. LED is
turned on.

[GAGE No. LED Indicator]

TIP • CH numbers (01 - 99) will be automatically assigned

to the EV counters sequentially from the top as they
are connected via the RS LINK function. If only one
counter is connected, it is assigned CH numbers 01
through 06, which corresponds to CEL1 through
CEL6. For more information refer to chapter 5, "RS
LINK FUNCTION".

4.3 Switching the Peak Mode (with D-EV)

The internal counters, CEL1 - CEL6, will hold (lock) the peak
values (Max., Min., and TIR) of the count values. Therefore, by
switching the peak mode with the MODE key, it is possible to
switch the value to be displayed (on the D-EV) or output.

(1) Press the DISP key to select a CEL number. The count

value of the selected CEL will be displayed (on the D-EV)
or output.

(2) Press the MODE key to switch the peak mode.

• Set a lower tolerance limit that is equal to or smaller
than the upper tolerance limit. An incorrect setting
may cause a tolerance setting error (Err90). If this oc­curs, press the P.SET key and perform the input op­eration again, starting with the lower tolerance limit.

• In the case of using the EV-16D, perform presetting/
tolerance limit setting with the linear gage connected,
as the connected linear gage sets the resolution auto­matically

TIP • If the RS-232C communication function is used, a pre-

set value/tolerance value of a maximum of eight digits
can be set.

• The factory-set default preset value, lower limit value,
and upper limit value are as follows:
If a 1µm gage is used:00000.000 / -99999.999 /

99999.999

4.6 Clearing the Error State

The error state can be cleared with the following procedures.
If the EV-16Z is used, push in the spindle to pass through the
origin after completing the following procedures.

(1) Press the DISP key to select a CEL number in the error

state. Then press P.SET key.

(2) The HOLD input signal rises to "H". (I/O)
(3) Input the CS command. (RS-232C)

NOTE • While the error state is being canceled, Error40 is dis-

played (on D-EV) or output.

• While the error state is being canceled, the GAGE No.
LED flashes.

• Time required for error cancelation: 30ms (EV-16P
and EV-16Z), max. 8s ( EV-16D)

4.7 Presetting (with the D-EV)

Replace the current value with a preset value.
(1) Press the DISP key to select a CEL number. The count

value of the selected CEL will be displayed (on the D-EV)
or output.

(2) Press the MODE key to select the current-value mode.

The on/off pattern of the LEDs show the selected mode.

[MODE LED Indicators]

(3) Press the P.SET key to replace the current value (displayed

value) with a preset value. At this time the peak values will
be cleared and Max. = Min. = Current value, and TIR = 0.

TIR

MAX MIN

NOTE • The EV Counter can count a maximum of eight digits,

however the D-EV Counter can display a maximum of
six digits. If a number has more than six digits, the
most significant one or two digits will be represented
by an "F". If the count value returns to a number of six
digits or less, the D-EV also returns to normal display.

Example)
Count value of EV Counter main unit: 1000.001
Display on the D-EV: F00.001

• If the EV-16D is connected to an ABS_ORG type
gage, approximately four seconds is required for the
preset value to be recalled on the EV-16D. During this
time do not move the spindle. Doing so may displace
the zero point.

• An ABS or ABS_ORG type gage can be preset one
million times (nominal).

5.2.7 Time required for RS-232C data output

The maximum output time (ms) as a result of executing the all­data output command (GA00CRLF) is calculated as follows:
= (number of connected counters x 10) + (number of available
channels x 17) + 6
[= (number of connected counters x 10) + (number of available
channels x 8.5) + 3]
Transmission speed: 9600bps [19200bps]
(Example)
One EV-16P unit (total 6 gage channels): Max. 118ms [64ms]
Ten EV-16P units (total 60 gage channels): Max. 1126ms [610ms]

NOTE • "Number of connected counters x 20" is used for EF

Counters.

• The above figures do not include personal computer
processing time.

• The data size required if total 60 gage channels are
used, is 900 bytes (15 bytes per gage channel). For
more information refer to the specifications of the re­ception-side personal computer.

• One or more EF Counters can be combined with the
EV Counters. However, if this is done, a maximum of
six EF Counters can be combined. A D-EV, if in­serted, will not be included in the number of con­nected units.

• The maximum total length of the RS LINK cables
used in the entire system is 10m.

• Consult Mitutoyo to construct a system with more
than 10 counters and/or a total cable length greater
than 10m.

6.2 Start-Up Method

Start up the entire system with the following procedure.
(1) Either turn on the power to all the EV Counters/D-EVs si-

multaneously or turn on the power sequentially, starting
from the top EV Counter/D-EV. The initial setup will com­mence.
During initial setup, the D-EV displays a flashing "-----".

(2) If the initial setup has been completed, the flashing "-----"

on the D-EV will fix (indicating the counting stand-by
state).

(3) Quit the counting stand-by state by either pressing the

P.SET key or by inputting an external HOLD or RS com­mand. (Refer to section 8.4 List of Error Outputs.)

NOTE • RS-232C-related parameters can only be modified on

6 - 2

the top counter.

• If the existing parameters are modified, reset the
power to all the connected counters.

• Always set the start-up mode to the counting stand-by
mode (factory-set default).

6 RS LINK FUNCTION

6.3 Troubleshooting

If communication with the personal computer is not functioning
well, refer to the following examples:

• If no response to the entered command is received from the

EV Counter.

1) Is the RS LINK cable connected properly?

2) Is a straight-type RS-232C cable used?

3) Are the personal computer and EV Counter communica­tion conditions consistent?

4) With some computers it is necessary to specify the com­munication port and whether it is to be used. Is a cable
properly connected to the specified port?

5) Is key operation or parameter setup operation being per­formed?
(During the above-mentioned operations, RS-232C com­munication function is paused/suspended.)

• The initial setup operation cannot be terminated ("-----"

flashes on the D-EV).

• Some counter enter the counting stand-by state ("-----" is

displayed on the D-EV) while the power is being turned on.

1) Is the RS LINK cable connected properly?

2) If EF Counters are being used with EV Counters, make
sure that the Digimatic selection parameter of the EF
Counter is set to "RS LINK".

After removing the cause of the error, reset the power
to all counters.

• A command (such as a zero-set or preset command) from

the personal computer can be executed, but no data can be
acquired. Or, data processing is stopped during data acquisi­tion.

1) Is the response output from the counter read with such as
the zero-set command, etc?

2) Is the next command issued before the response output
from the counter is received?

3) Is the number of channels connected via the RS LINK
function consistent with the number of data pieces to be
acquired?

• A command abnomaly occurs if a command is issued.

1) Was a command consisting of 2-byte characters or lower­case characters issued?

2) Don't you specify a number greater than the number of
channels connected?

7 I/O FUNCTION

6) Relationship between the measurement value and output
terminal
If a segment output is designated, the output terminal (corre­sponding terminal Ln) corresponding to the measurement
value is turned ON.
'n' of corresponding terminal Ln (-10 ≤ n ≤ +10, n is an inte­ger) can be calculated as follows. (If n is between -10 and -1,
the corresponding terminal will be between -L10 and -L1.)

Peak mode Formula for n

Current value If the measurement value is positive:
MAX
MIN

n = INT{(measurement value + 1/2 resolution)
/resolution}
If the measurement value is negative
n = INT{(measurement value - 1/2 resolution)
/resolution}

TIR

n = -10 + INT(measurement value/resolution)

7) Output pattern
The segment output pattern varies with the peak mode
setup.

Peak mode Output

Current value
MAX
MIN
TIR

Only the corresponding terminal, Ln, is ON.
Corresponding terminals from -L10 to Ln are ON.
Corresponding terminals from Ln to +L10 are ON.
Only the corresponding terminal, Ln, is ON.

NOTE Output at range-over

Should a +0V (the measurement exceeds the upper
limit) or -0V (the measurement falls below the lower
limit) range-over occur, all terminals between -L10 to
+L10 will be set to OFF.

TIP • Difference between CH01=A and CH01_A

A CEL that is represented so as to include "=" when
the display is switched with the DISP key, is output
with the I/O function. A CEL that is represented so as
to include "_" is not output by the I/O function.

• How to make general tolerance judgment
Before tolerance judgment output, set the I/O output
logic parameter to "Output terminal is H". This en­ables general tolerance judgment, in which the output
is "H" if all the CELs, which are connected in such a
way that the GO output of each CEL is connected by
means of hard-wire OR operation, result in GO.

7.5 Calculation Mode

7.5.1 Overview of the calculation mode

1) Using the CEL that has been specified by the calculation
axis designation parameter, output the calculation result
specified by the input of SET1 to SET3, as shown below.

2) Setting the calculation method
(For the detailed procedure, refer to section 7.7.5 Designating

CELs to be output/Specifying the calculation method .)

7.5.2 Tolerance judgment result output

1) Function

• A tolerance judgment of the calculation result will be out-

put from CEL6.

• In case of no calculation, a tolerance judgment to the

count value of CEL6 will be output.

• The tolerance limits for CEL6 will be applied.

2) Parameter setup

•

I/O function selection parameter: Set to the calculation mode.

• I/O-type selection parameter: Set to tolerance judgment.

• Calculation axis designation parameter:

Select one between 0 and 3.

Calculation method

Sum of CEL data on specified calculation axes
Mean of CEL data on specified calculation axes
Max. of CEL data on specified calculation axes
Min. of CEL data on specified calculation axes
MAX - MIN of CEL data on specified calculation
axes

TIP • Display on the D-EV when the calculation mode is be-

ing set.
If the display is switched with the DISP key, the follow­ing will be sequentially displayed after normal display
(CH01 to CH06 and 6-axis tolerance judgment bar):
Displays the sum after displaying CL01_1.
Displays the mean after displaying CL02_2.
Displays the maximum value after displaying CL03_3.
Displays the minimum value after displaying CL04_4.
Displays the MAX - MIN after displaying CL05_5.
For the second EV Counter on the RS LINK, the fol­lowing will be displayed:

7 - 10

No. 99MBC034B

Displays the sum after displaying CL07_1.
Displays the mean after displaying CL08_2.
Displays the maximum value after displaying CL09_3.
Displays the minimum value after displaying CL10_4.
Displays the MAX - MIN after displaying CL11_5.
* All the keys except the DISP key will be disabled in

the calculation mode.

• Difference between CH06=F and CH06_F.
If the setups of SET1 to SET3 are not '000' (some
calculation item has been specified), and if CH06 is
specified with the DISP key, the measured value will
be displayed after 'CH06_F' is displayed. This means
that "_" indicates that tolerance judgment output is not
performed for the CH06 measurement value (i.e. the
tolerance judgment output is performed for the calcu­lation result).
In other cases, where SET=000, a tolerance judg­ment will be output to the measured value of CH06
and the measured value will be displayed after
'CH06=F' is displayed.

7.5.3 BCD output

1) Function

• Outputs the calculation results specified by SET1

through SET3 as the BCD data.

• Outputs the data of all CELs as a time-division BCD, if

the setups of SET1 to SET3 are "000".

2) Parameter setup

•

I/O function selection parameter: Set to the calculation mode.

• I/O-type selection parameter: Set to BCD output.

• Calculation axis designation parameter:

Select one between 0 and 3.

NOTE About operation during suspension

• Presetting, peak clear, or zero-setting operation (with
D-EV, I/O, RS-232C) for CELs other than those which
have been specified by SET1 through SET3 will be
suspended, and they become effective only after the
CEL has been specified.

•

Even if the tolerance judgment bar display is active, only
the bars of CELs that have been specified will operate.

•

RS-232C output from CELs other than those which have
been specified by SET1 through SET3 will be the previ­ous data (existed when the suspension state began).

• If the CELs, excluding that which is displayed on the
D-EV, are specified for output CEL designation, the
display values will be held (locked).

•

If key operation is attempted on the D-EV, the I/O func­tion will output all CEL data in a time-division format.

Output CEL
