r1912[0] Identified stator
resistance [Ohm]
Displays measured stator resistance value (line-to-line). This value also includes the cable resistances.
Index: [0]
Notice: If the value identified (Rs = stator resistance) does not lie within the range 0.1 % < Rs [p. u.] < 100 % fault
message 41 (motor data identification failure) is issued. P0949 provides further information (fault value = 2
in this case).
Note: This value is measured using P1900 = 2.
r1920[0] Identified dynamic
leakage inductance
Displays identified total dynamic leakage inductance.
Index: [0]
r1925[0] Identified on-state
voltage [V]
Displays identified on-state voltage of IGBT.
Index: [0]
Notice: If the identified on-state voltage does not lie within the range 0.0V < 10V fault message 41 (motor data
identification failure) is issued. P0949 provides further information (fault value = 20 in this case).
r1926 Identified gating unit
dead time [μs]
Displays identified dead time of gating unit interlock.
P2000[0...2] Reference frequency
[Hz]
P2000 represents the reference frequency for frequency values which are displayed / transferred as a
percentage or a hexadecimal value.
Where:
hexadecimal 4000 H ==> P2000 (e.g.: USS-PZD)
•
percentage 100 % ==> P2000 (e.g.: AI)
