Motor data identification - synchronous motor

Synchronous motor
Table 7- 13 Data determined using p1910 for synchronous motors (stationary measurement)
Determined data
r1912 stator resistance identified
r1925 threshold voltage identified
r1932 d inductance
r1934 q inductance identified
r1950 Voltage emulation error
voltage values
r1951 Voltage emulation error, current values
Note regarding r1950 to p1953:
Active when the function module "extended torque control" is activated and activated compensation of the voltage
emulation error (p1780.8 = 1).
r1973 Encoder pulse number identified
Note:
The encoder pulse number is only determined very imprecisely and is only suitable for making rough checks (p0408). The
sign is negative if inversion is required (p0410.0).
r1984 Pole position identification angular difference
Note:
r1984 indicates the difference of the angular commutation offset before being transferred into p0431.
-
Note:
If the encoder inversion is changed using MotID, fault F07993 is output, which refers to a possible change in the direction
of rotation and can only be acknowledged by p1910 = -2.
