I know what You are trying to tell me, but is there more simple way, since my application if fairy simple. I can not use fixed setpoints - and JOG is exactly what I need and that is what it was designed for... I've had many applications build like this before and had no problems. So I find it unbelievable that new product is so hard to configure for basic things... My application: No profibus (will be in use in the future). I use DI0 for normal ON/OFF, analog potentiometer for speed reference and DI2 for JOG (inching the machine) signal. JOG is set to 250 RPM. Normal operational speed is around 1500 to 3000 RPM. I need linear speed reference for normal operation - can not use fixed setpoint. And normal start has to be smooth - ramp 5-10 second. But JOG has to start almost instantly - no ramp. These are basics requirements for the application that I have. Thx!

When using JOG (via profibus now) - response is very slow, since SP is going via RFG. So I want to disable RFG when using JOG (P1122) BUT I cannot access this parameter! It is simple not there! So my million dollar question is, how to disable RFG on Sinamics G120 with BICO!? THANK YOU!

When you Jog, change to CDS1 using CU's I/O, and in the end of Jog operation, change it back to CDS0.
