CPU 1212c, how to configur PID

Pegaia

Hi,

normally the encoder is connected directly to the driver to get more accurance.
If you decide to use the PLC, however, I suggest this way
1 - configure a HSC to read pulses
2 - in a time OB read the pulses, and convert it to frequence (speed = k * delta pulses number); e.g. k = gear ratio/time inteval). note convert the values to float point
3- in the same ob use a PID to control the speed; analogica output -> drive reference.

 Hi,

This is very helpful thanks

but i need more details

my project is to use CPU 1212c DC/DC/DC and 2 pulse encoder 100PPR

the cpu with the aid of analog o/p to drive dc 'SPRINT DRIVE'

what i need is analog signal Acceleration Referance Speed Deceleration with the encoder feed back

the speed never excced 400mm/s

how to configur PID to give the analog
