Miguel Rojas Brenes Posted September 30, 2021 Report Share Posted September 30, 2021 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.
