OVERVIEW

This chapter outlines the features of the EV

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.

By setting the appropriate parameters it is possible to connect a single gage output either to one internal counter or to multiple internal counters. With this function, multiple origins and tolerance setups can be set for a single gage.

Origin setup, peak measurement, and tolerance setup can be performed individually for each of the six internal counters (CEL1 - CEL6).

Calculation function:

Each of the internal counters has a specific calculation function. Therefore, calculation can be performed between the counters specified by the parameters.

2.1 Installing the EV Counter

Both the front and rear panels of the EV Counter have four mounting holes. Use the fixing legs and junction brackets which come as the standard accessories to install the EV Counter.

a) The fixing legs

(1) Attach the fixing legs (4 places) on

the counter main unit using the supplied screws.

(2) Use the oval hole provided on each

fixing leg to secure the counter to an appropriate surface.

b) The junction brackets

Use the junction brackets and supplied screws to join the two panels along the vertical.

• Use a 12 - 24VDC power supply with a control output current of 1A or greater. Do not draw power from a source which is used by highpower equipment.

• Do not route the power cable, I/O cable, RS232C cable, RS LINK cable, or gage connection cable with other power cables.

• Use a shielded I/O cable not longer than 3m.

• Always ground.

• Each cable should be secured (to, for example,

the main body of the device).

NOTE Always use the RS LINK connection cable specified by

Mitutoyo. Refer to section 8.3 Optional Accessories.

(2) To link more than one counter with the RS LINK connec-

tion cables, refer to chapter 6 RS LINK FUNCTION.

TIP The D-EV will display the data of the EV Counter which

is connected to the RS LINK IN connector of the D-EV.

2.2.3 RS-232C, I/O/BCD, and RS LINK connections

The EV Counter has an RS-232C connector, I/O/BCD connector, and RS LINK connector. If these connectors are used, refer to chapter 5 RS-232C COMMUNICA-

TION FUNCTION; chapter 6 RS LINK FUNCTION; and chapter 7 I/O FUNCTION for information about cable connec-

tions.

2.2.4 Connecting the power supply and grounding

The EV Counter and D-EV do not have a power switch. Power is supplied by connecting the power source to the +V and -V terminals on the power inlet terminal strip.

IMPORTANT Positively ground the grounding terminal.

2.3 Power On

When the power source is connected to the EV Counter, it enters the counting stand-by state. To start operation and enter the counting state, quit the stand-by state.

TIP The counting stand-by function is an alarm function that

is entered if there is a power interruption during use.

a) If a D-EV is not connected

(1) If the EV-16P or EV-16D is used,enter the RS-232C com-

mand or I/O signal (a HOLD signal to clear the error) in the EV Counter. For information refer to chapter 5 RS-232C

COMMUNICATION FUNCTION; and chapter 7 I/O FUNCTION.

(2) If the EV-16Z is used, push in the spindles of all connected

gages to pass through the origins after completing the procedure (1) described above.

b) If a D-EV is connected

(1) When the EV Counter and D-EV are on, the counting stand-

by state is entered.

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.

SETTING PARAMETERS

This chapter describes the method used to set

the parameters required to use the EV Counter.

3.1 Setting Parameters (with D-EV)

Before using the EV Counter, various parameters must be set up. This section explains the setup method using the essential parameters, "gage resolution" (for EV-16P and EV-16Z) and "designation of available axes", as examples.
