Hello,
I use a Siemens Sinamics G120C inverter in combination with a S7-1200 cpu.
I use the Main Setpoint with the Providrive option and send 1810 rpm to the inverter.
Now I use r722.3 digital input to select a fixed speed of 300 rpm.
But when I activated this input the totaly speed will be 2110 rpm, the fixed speed will be added.
See attachment.
I can calculated to get 300 rpm but when the main setpoint changes I get another speed then 300 rpm.
So independent of the main setpoint via Profidrive (I must use this for other situations) when I activated r722.3 always the drive must be 300 rpm.
Who can help me to fix this?
Thanx, mulderm
