7.1.12.2 Motor data identification - synchronous motor
Synchronous motor
Table 7- 13 Data determined using p1910 for synchronous motors (stationary measurement)
Determined data Data that are accepted (p1910 = 1)
r1912 stator resistance identified p0350 motor stator resistance, cold
+ p0352 cable resistance
r1925 threshold voltage identified -
r1932 d inductance p0356 motor stator leakage inductance
+ p0353 motor series inductance
p1715 current controller P gain
p1717 current controller integral-action time
r1934 q inductance identified -
r1950 Voltage emulation error
voltage values
p1952 Voltage emulation error, final value
r1951 Voltage emulation error, current values p1953 Voltage emulation error, current offset
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 p0431 Angular commutation offset
Note:
r1984 indicates the difference of the angular commutation offset before being transferred into p0431.
- p0410 Encoder inversion actual value
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.
