3.5 Conversion ratio of the setpoint and actual values (P607 and P608)
The position values are based on the number of rotations of the motor. If a different reference value is
required, with the aid of parameter P607 [03] the "Speed Ratio" and P608 [03] the "Reduction Ratio" can be
converted into a different unit. No values after the decimal point can be entered in the parameters "Speed
Ratio" and "Reduction Ratio". In order to achieve greater precision, the two values should each be multiplied
by the same factor, which should be as large as possible. The product must not exceed the value 6500, i.e. the
factor must not be too large.

NOTE: The required unit can be selected in parameter P640 "Unit Pos. Value". In the example, the
parameter P640 "Unit Pos. Value" must be parameterised to the function 4 = cm.
