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° .
P-AXIS-00206:
Variable name | Type | Permissible range | Axis type | Dimension |
v_reso_num | UNS32 | 0 < v_reso_num < MAX(UNS32) | T, R | Increments |
P-AXIS-00205:
Variable name | Type | Permissible range | Axis type | Dimension |
v_reso_denom | UNS32 | 1 < v_reso_denom < MAX(UNS32) | T | 1µm |
|
|
| R | 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 // [Minutes]
v_reso_num = 10000 // [Increments]
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 // [Minutes]
v_reso_num = 1 // [Increments]
v_reso_denom = 1000 // [1 μ m]
