[Flow pack Machine Program]

Hi,

I'm working on a flow pack machine, it has got all the mechanical parts and the sensors and the actuators with an HMI/PLC Which I can't access, and it's working,
but I want to change the hmi and to add a Siemens S7-1200 plc And I have to make a program  to have the same function ,
I managed to make a little plc program to read all the sensors and the encoder value and to cmd all the motors, but I don't know how to synchronize between the film cutter and the film.

I have a VFD that runs the film cutter (it's a rotary resistor which cuts and seals the product package) and a potentiometer to adjust the speed of the VFD and an encoder attached to the chain of the film cutter
and I also have a servo motor which pulls the film and I control the position and speed of this Servo from the plc
I don't know how to synchronize between the speed of the film cutter (VFD) and the speed of the
film (Servo drive) so I could have the same length of the product in all speeds

I also have an eye color sensor, and I don't know what to do when the eye color sensor detects the eye mark in the film.

Any help appreciated ,

No, expansion units cannot be used for pulse output.  Only CPU OUT 100.00,100.01,100.02 and 100.03.

thank you so much for your help

High speed outputs will ONLY work if the model has transistor outputs.

Thanks for your reply , so the CP1E-N40S1DR-A is relay output ,can I add a transistor output module as an expansion and use its output for pulsing?

Welcome to the forum.

MOV instruction will only move 4 digits.  Use MOVL to move 8 digits.

Right now your target frequency is set to 0.

Additionally your plc has relay outputs.  It will never be able to switch at 50000 hertz.

Thanks for your reply 
yes I just found out that my outputs are relay type, 
I changed the mov instruction to movl for the target freq and also I lowered the Frequency to 10Hz but the outputs still off, is the plc must be transistor type 
to make the outputs toggle,

Hello All,
I'm a newbie to Omron programing 
I have a program where I want to control a stepper motor with 1 plc output "pulse output0" 
in my program I used PLS2 instruction but when I execute the instruction the motor won't rotate and the plc outputs are off, My wiring is fine, and my plc is CP1E-N40S1DR-A
MY 1st output is pulse output 0 Q100.0 and also the driver wiring with the stepper motor is good ( I did a test with siemens plc the motor does work fine ) , what could be the problem? thanks,
