Hello.
I am working with a PLC Samba SM70-J-RA22, Remote I/O Adapter EX-RC1 and I/O Module IO-D16A3-TO16.
I have a problem. I am using the HSO and the HSC of IO-D16A3-TO16 for stepper control. The HSO is connected to the HSC, so I read the number of pulses.
I have different target of pulses, but I can´t get the target that I need. For example, If I need a target of 15 pulses, I get 18, 30 or 100. The target is near when I use a low velocity (15, 17 or 18), but in my application I use a high velocity. Therefore the motor stepper moves different pulses's number.
In the HSO of the I/O Module IO-D16A3-TO16,only I have two parameter: output frequency and duty cycle.
Also, I work with virtual HSC.
I attach some images of the program.
For information:
MI21: Frequency HSO.
MI7 :Set Target.
MI11: Virtual HSC.
MI12: Pulses´s number each cycle.
Please I need your help.
Regards.
