【 4.4 】 XMT Passive Current Signal
【 Mode Switch 】
:When the main interface 【 FN 】 is white.Press 【 IN/OUT 】 to switch
the display of actual value and engineering quantity of input/output
【 Output Range 】
: The limit range of passive current output can be set
【 4.5 】 Hz Pulse Signal
【 Mode 】
: The pulse signal has four modes: frequency, PWM duty cycle, speed frequency,
pulse quantitative/counting. For input, when the main interface 【 FN 】 is white,
press 【 IN 】 to switch the mode directly. For output, long press 【 OUT 】 to switch mode
【 Range 】
: Select the range of frequency output: 0~99.999Hz, 0~999.99Hz,
0~9999Hz, 0~200kHz
【 Method 】
: Select level/open circuit according to the presence or absence of pull-up
【 Output Peak Value】
: The level height of the output waveform, the highest is 24V
【 Input Counting Method 】
: The rising edge means that the level rises from 0V to
the peak value of the pulse, and the counter is incremented by 1. A falling edge
indicates that the input level falls to the OV counter and increments by 1.Jump
means that as long as the input level jumps up and down, the counter is
incremented by 1. Long press 【 IN 】 to clear the count
【 Frequency Mode Operation Instructions 】
: The input frequency range is
0~9999Hz, which cannot be selected, and the displayed decimal point is
automatically shifted.The output frequency range can be switched by
pressing 【 OUT 】 when the main interface 【 FN 】 is white
【 Operating Instructions In PWM Mode 】
: PWM displays two parameters, the
frequency value (that is, the period value) and the duty cycle.The frequency value
will be displayed in the original engineering quantity position (no engineering
quantity display).Note that the maximum frequency does not exceed 9999Hz.The
frequency value/duty cycle parameters can be set when outputting.When the main
interface 【 FN 】 is white, press 【 OUT 】 to switch, there is a yellow cursor indication
【 Operating Instructions For Speed Mode 】
:
(1)
The speed mode is used to calculate the speed of the motor or gear. One
revolution of the motor or gear produces 1 pulse, one minute is 3000 revolutions, so 1
second is 50 pulses
(2)【 Time Unit 】
: Frequency=RPS(per second)*number of pulses per revolution,
RPM(per minute)=RPS*60, RPH(per hour)=RPS*3600.In the speed setting selection,
note that the maximum frequency does not exceed 9999Hz
(3)【 Number Of Revolution Pulses 】
: The number of pulses per revolution of the
motor or gear, which can be selected in the speed setting
(4)【 Tooth Missing 】
: It is mainly used to simulate the engine speed, select it in the
speed setting
【 Quantitative/Counting Mode Operation Instructions 】
: The main purpose of
pulse quantitative is to simulate the quantitative control sensor of flow, and the pulse
count is to simulate the flow of count.For inputs, the input frequency value will be
