Operation
■ Main Functions
Input Types and Ranges
Scaling
Analog (Process) Inputs
The K3GN converts input signals into desired physical values.
INPUT2:
Any input value
DISPLAY2: Displayed value corresponding to INPUT2
INPUT1:
Any input value
DISPLAY1: Displayed value corresponding to INPUT1
Pulse Frequency
The K3GN converts pulse signal inputs into desired units such as
revolutions or rotational speeds.
The slope of the linear relationship between the input value and dis-
play value is calculated automatically when an input value and its
corresponding display value are entered.
Input value: Any arbitrary input value
Display value: Desired display value corresponding to input value
If scaling for pulse signals is not performed, the input frequency will
be displayed.
The relationship between input, f, and display, D, is expressed in the
form D = f
× a (multiplication factor). The value of a will vary accord-
ing to the display unit. For example, if the display unit is rpm, Y is
given by the following:
D = f
× 1/N × 60 (i.e., a = 1/N × 60)
where N is the number of pulses per revolution and f is the input
pulse frequency (Hz).
If the display unit is m/min, Y is given by the following:
D = f
× πd × 1/N × 60 (i.e., a = πd × 1/N × 60)
where
πd = the wavelength (m) per revolution.
Example: When displaying the rotational speed (rpm) for a machine
that generates 5 pulse signals per revolution, D is given by the follow-
ing:
D = f
× 1/5 × 60,
so if f = 1, then D = 12. Therefore, input 1 for inp and 12 for dsp.
Average Processing
The average processing function stabilizes displayed values by aver-
aging the corresponding input signals that fluctuate dynamically.
Hysteresis
The hysteresis of comparative outputs can be set to prevent the chat-
tering of relay or transistor outputs.
