Omron MC421

Hello, I would like to slow down a servo motor. It is a Yaskawa Sigma 7 servo amp and motor controlled by an Omron MC421. I am not sure if it is better to do this through the Yaskawa parameters or the Omron parameters. I only want the one axis slowed down (it is a 3-axis machine). The MC421 is using G-code programming. It will move all 3 axes at G00, simultaneously and it's great for 2 of the motors however, the third axis moves way to fast. I wasn't sure if simply changing this, would work:
