Normalization of the velocity (Nominator/ Denominator) (P-AXIS-00206/ P-AXIS-00205)

The normalization of distance (path or revolution) in time interval is handled equal to the path resolution in transducer systems with setting of nominator and denominator of a quotient.

The nominator gives the number of increments, whereas the denominator gives the path in 1 μm or 0,001° .

Example 1:

The motor provides 2 ^ 20 increments per revolution. The velocity interface should provide the increments per sample interval additionally with factor 2 ^ 8, so the following settings are necessary:

v_time_base        =
2         // [cylce time]v_reso_num         =
268435456     // = 2 ^ 28 [Increments]v_reso_denom           =
360000    // [0.001 °]

Example 2:

The drive expects 10E-4 revolutions per minute on velocity interface.

v_time_base        =
0         // [Minuten]v_reso_num         =
10000     // [Inkremente]v_reso_denom           =
360000    // [0.001 °]

Example 3:

The drive expects 10E-4 revolutions in mm per minute on velocity interface.

v_time_base        =
0         // [Minuten]v_reso_num         =
1         // [Inkremente]

v_reso_denom = 1000 // [1 μm]
