Setpoint, rotation- and ramp setting
Parameter oP.64 adjusts the reference value of the calculation and is dependent on ud.02.
oP.63 Ref. value high-resolution
The factor for the setpoint calculation is adjusted here:
oP.63 x oP.64
———————
2
30
Setpoint =
That means: If value 2
30
is preset for oP.63, the setpoint is equal to oP.64 "ref. value high-resolution"
The maximum for the setpoint is twice the reference value.
The achievable high resolution is calculated as follows:
oP.64
——————
2
30
High resolution =
If oP.64 is set to 2000rpm, i.e., the half maximum value (4000 rpm mode), the high resolution is:
2000 rpm
——————
2
30
High resolution = = 1,86 x 10
-6
rpm
This should sufce for all applications.
The adjustment value for oP.63 is calculated as follows:
desired setpoint
———————————
oP.64
oP.63 = x 2

Example 1
Reference value (oP.64): 2000 rpm
requested setpoint: 0.140624 rpm
0.140624 rpm
——————
2000 rpm
oP.63 = x 2

= 75497
