One of the conversion ratios of gearboxes driven by servos It is not an integer. In this case, when the gearbox rotates 1 revolution, the motor the number of turns is fractional, but the engine in the technology object the number of turns can be entered as an integer. can you suggest a solution? The PLC I use is S7-1500 servo drives V90 Regards

For example: Gear box IN: 1 revolution Gear box OUT: 0,67 revolution -> You have to use the integer values 1000 and 670 or 100 and 67
