Support Required in Using SPD function

6 posts in this topic

Hello all

I am have FX3G PLC, where i am trying to use SPD function for speed monitoring and controling. currently i am working on software only.

I am using x4 as input (s1) , sk1000 (s2), and d4 (D)

in monitoring mode when i am forcing X4 to ON/OFF ,  there is no any value change occure on d4

i have tried to change the s2 value from k1000 to k10000, but not fruitful

i need your valuable support to confirm that my primary setup is correct or not and what things are required/missing

attached program screeshot

Good morning

I trust you are well. 

I would suggest shortening your time. Please see attached picture on how to calculate the time

The SPD instruction does not work in simulation mode.

Good Day sir,

First of all i would like to say thank you for your response on my post.

I have one query , regarded the SPD function,

is it possible to simulate like forcing ON/OFF the input used for SPD and get result at out put.

what i cam to know from that it require a minimum frequency at input which can not be achieved by manually forcing ON/OFF the input (e.g X004) of SPD

If it really require a minimum frequency at input, then is there any way to simulate an input with particular frequency (without hardware

simply check the reponses you already got. the very first one shows info from the page of the manual. it shows exactly what SPD does, with all parameters etc. as well as equation it is built on. that equation is the key to do any simulation without actual PLC hardware. minimum frequency is determined by value in S2.
