INPUT

Teaching with actual values is possible.

Instead of setting by inputting with the Up Key and Shift Key, current values can be

input as scaling input values for teaching. This is useful for making settings while checking the

operation status of the K3MA-F.

The initial value will change depending on the

pulse frequency selection.

When displaying the decimal point, consider the

number of digits to follow the decimal point prior to

setting the scaling display value.

If p-fre is set to 30, the initial setting for the

decimal display will be 000.00.

Note:

K3MA-F

Convenient Functions

Scaling Teach

The parameter (inp) for the K3MA-F’s initial setting level can be set using actual input values with the teaching function. After displaying the param-

eter, the actual input settings can be made with the following operation.

OUT Types (Comparative Output Models Only)

OUT 1 and OUT 2 can be set to operate in one of the three following

modes in accordance with the compared values:

•Upper limit (High Acting):

The output is turned ON when the measurement value is greater

than its set value.

•Lower limit (Low Acting):

The output is turned ON when the measurement value is less than

its set value.

•Upper and lower limits (Outside Band Acting):

An upper limit (H set value) and lower limit (L set value) can be set

independently.

The output is turned ON when the measurement value is greater

than upper-limit set value or less than the lower-limit set value.

The three types of output operations shown above can be combined as desired. The following are examples of possible combinations.

Parameter Initialization

This function returns all of the parameters to their initial values.

Use this to reset the K3MA-F after returning it to its factory-set condi-

tion.

K3MA-F

Average Processing

Average processing stabilizes the display by minimizing any pulsat-

ing or flicker caused by fluctuations in the pulse width of sensor input

or by eccentricity in rotating shafts.

Hysteresis (Comparative Output

Models Only)

The hysteresis of comparative outputs can be set to prevent chatter-

ing in the output when the measurement value fluctuates finely near

the OUT value.

Auto-zero Time

This function sets the time for the display to return to zero when input

pulses stop. Set the time longer than the expected input pulse cycle

(the interval between one input pulse and the next). Proper measure-

ment is not possible if the time is set shorter than the input pulse

cycle.

Setting range: 0.0 to 19.9 s

Startup Compensation Time

The startup compensation time is the time to wait for the

measurement operation to be entered after the power supply of the

K3MA-F is turned ON. Use this parameter to cancel measurement

and comparative output operation until the a rotating body reaches

its normal speed when the power supply to the K3MA-F and rotating

body are turned ON at the same time.

Changing the Display Color

The color of the value displayed can be set to either red or green. For

comparative output models, the display color can be set to change

from green to red, or from red to green, according to the status of the

comparison criterion.

Display Auto-return Time

This function automatically returns the display to the operation level’s

current value if no keys are pressed for a preset time (called the dis-

play auto-return time).

Move-to-Protect-Level Time

The time required to shift to the protect level can be set as desired.

MAX/MIN Display

The maximum and minimum measurement (display) values from the

time the power is turned ON until the current time can be stored and

displayed. This is useful, for example, when measuring the maximum

value.

■LCD Angle of View

The K3MA is designed to provide the best visibility at the angles

shown in the following diagram.

■Watertight Cover

■Rubber Packing

K32-P1

If the rubber packing is lost or damaged, it can

be ordered using the following model number:

K32-P1.

(Depending on the operating environment,

deterioration, contraction, or hardening of the

rubber packing may occur and so, in order to

ensure the level of waterproofing specified in

NEMA4, periodic replacement is

recommended.)

Note: Rubber packing is provided with the

Controller.

■Wiring Precautions

•Use crimp terminals.

•Tighten the terminal screws to a torque of approximately 0.5 N⋅m.

•To avoid the influence of noise, route signal lines and power lines

separately.

■Wiring

•Use the following M3 crimp terminals.

■Unit Labels (Provided)

•The unit labels are not attached to the K3MA-F. Select the desired

labels from the provided sheet.

Note: For scales and gauges, use the unit labels that are specified by

the relevant laws or regulations.

■Setting Example

Initial Settings

The settings for the following example are shown here.

Example: Display conveyor belt feed speed

Here, the conveyor belt feed speed is to be displayed in units of

0.1 m/min.

•Proximity Sensor: E2E-X5E1, NPN output

When displaying a flowrate (e.g., in l/min or l/h), make the scaling

settings after confirming the I/O characteristics of the flowrate sen-

sor. There are flowrate sensors that output analog signals. If this kind

of flowrate sensor is used, consider using the K3MA-J.

1. Select the maximum input frequency for the K3MA-F.

Set the pulse frequency selection to either 30 Hz or 5 kHz. In the

example, this is set to 30 Hz because the conveyor belt is turning

at a slow speed.

Parameter: p-fre (pulse frequency), Setting value: 30

2. Set the scaling. The display value (D) is shown with the following

formula.

D = f × α,

f: frequency and

α: prescaling value

The value of α will be internally calculated and registered if the

input value (f) and the display value (D) are set.

The number of rotations or speed is shown with the following for-

mula.

Rotations (rpm) = Frequency input/No. of pulses

per rotation × 60

Cycle speed D (m/min)= Rotations × roll circumference

= 1/N × f × 60 × d × π

N: No. of pulses per rotation

f: Frequency (Hz)

d: Roller diameter (m)

When the input conditions are applied to this equation, we obtain

the following:

Display value = 1/1 × f × 60 × 0.1 × π

For an input of 1 Hz, the display value is 18.8495 (m/min).

The scaling settings for the K3MA-F must be integers. Also, to

decrease error, the scaling value is multiplied by 1,000, to obtain

an input of 1000 Hz and a display value of 18850. However,

because the display value in this case is displayed to the first dec-

imal place, the scaling is set as shown in the following example so

that 1885.0 is displayed for an input of 100 Hz.

Parameter Setting value

inp (scaling input value) 100

dsp (scaling display value) 18850

dp (decimal point position) %%%%.%

Note: The decimal point position here refers to the position in the

number after scaling. When setting the scaling display value, it

is necessary to consider the number of digits to be displayed

past the decimal point.

■Troubleshooting

When an error occurs, error details will be displayed on the main indicator. Confirm the error from the main indicator and take the appropriate coun-

termeasures.
