Operating ModesServo controlInduction motorThe data are identified in the gamma equivalent circuit diagram and displayed inr19xx. The motor parameters p0350, p0354, p0356, p0358 and p0360 taken fromthe MotID refer to the T equivalent circuit diagram of the induction machine andcannot be directly compared. This is the reason that an r parameter is listed in thetable, which displays the parameterized motor parameters in the gamma equivalentcircuit diagram.Table 3-11Data determined using p1910 for induction motors (stationary measurement)Determined data (gamma) Data that are accepted (p1910 = 1)r1912 identified stator resistancer1913 rotor time constant identifiedr1915 stator inductance identified –r1925 threshold voltage identified –r1927 rotor resistance identifiedr1932 d inductancer1934 q inductance identified –p0350 motor stator resistance, cold+ p0352 cable resistancer0384 motor rotor time constant/damping timeconstant, d axisr0374 motor resistance cold (gamma)p0354r0377 motor leakage inductance, total (gamma)p0353 motor series inductancep0356 motor stator leakage inductancep0358 motor rotor leakage inductancep1715 current controller P gainp1717 current controller integral action timer1936 magnetizing inductance identifiedr0382 motor magnetizing inductance transformed(gamma)p0360 motor magnetizing inductancep1590 flux controller P gainp1592 flux controller integral action timer1973 encoder pulse number identified –Note:The encoder pulse number is only determined with a very high degree of inaccuracy (p0407/p0408) andis only suitable for making rough checks. The sign is negative if inversion is required (p0410.0).– p0410 encoder inversion actual valueNote:If the encoder inversion is changed using MotID, fault F07993 is output, which refers to a possiblechange in the direction of rotation and can only be acknowledged by p1910 = –2.3-102© Siemens AG 2006 All Rights ReservedSINAMICS S120 Function Manual, 03/2006 Edition
