Names andFunctions

I/O

The reset function serves to set a standard for measurement values
using a block gauge, for example. Resetting sets the current value to “0”.
If a preset value has been set, the current value becomes the preset
value.
Any of the following methods can be used to perform a reset:•

Key operation (Reset)•

Input via I/O (RESET)•

Transmission of a reset command via RS-232C (Zr)Reset

Note: Always reset after replacing the detector with a different one.

5-3-2 Preset Function

For details on setting a preset value, refer to 6-1 “Setting the SET No. Parameters”.
For example, when the instrument is reset with a block gauge or other reference, and you
wish to indicate that position as 3.5 mm, set a preset value of 3.5 mm.

5-3-3 Absolute Value Display and Relative Value Display
Absolute value display is the status where mechanically intrinsic measuring values are
displayed, taking the status where the detector’s spindle is projecting to the maximum extent
as approximately zero (actually it will be a little on the minus side).
Relative value display is the status where measurement values are displayed by taking theposition determined in master calibration using the reset operation described above as thereference.

7-4-4 Transmission without Using a Communication Command
The initial parameter P06 can be set to enable data output without use of communicationcommands from an external device.
This function is useful for output to a printer or the like.
Chapter

The internal timer or the EXT RS IN signal line is used as a data output trigger.

Instructions for
Safe Use

Internal timer mode (Initial parameter P06 = Sd-2)
Data is automatically output according to the internal timer. Data output starts when the poweris turned ON.

Details
Errors detected by the detector itself.
In most cases these are critical errors due to deterioration or to mechanical orelectrical damage.
In some cases they may also be temporary errors due to noise. To check, you arerecommended to replace the unit with a normal one and find out if the error also
occurs with the normal unit.
Detector-related errors detected by the display unit.
In most cases these are temporary errors such as connection mistakes.
Errors relating to internal control in the display unit.
Errors due to deterioration or to mechanical or electrical damage.
Errors relating to display unit operation, etc.
Note that communication-related errors can sometimes be temporary errors due tonoise.
To check, you are recommended to replace the unit with a normal one and find out if
the error also occurs with the normal unit.

Check
Is the power supply connected properly?
Is power being supplied properly?
Has the connection been made with the polarity (+/−) reversed?
Is the appropriate power voltage used?
Is there sufficient current capacity?
Is a hold signal being input?
When a hold signal is being input, “HOLD” is displayed in theupper right corner of the display.
Turn the power OFF, then disconnect and re-connect the detector.
Is the detector installed securely with no play?
Is the measurement terminal loose?
Is the detector being subjected to any excessive vibration or impact?
For example, when a detector is put on a guide rail and moved up
and down by an air cylinder, the impact from a strong collision withthe mechanical stopper on the upper edge (back clearance side)
may cause erroneous counting.
Install a shock absorber or other means of softening the impact,
reduce the air cylinder operation speed, or take other appropriate
measures.
Is the spindle moving up and down properly?
If the spindle is tightened excessively during installation, it may affectspindle operation.
Are the keys locked?
To unlock the keys, simultaneously hold down the [SET],[P-CLEAR] and [RESET] keys for about 3 seconds.
Turn the power OFF, wait a few seconds, and then turn the powerback ON.
