Parameter Function
Notice: Ensure that the motor holding brake is not active when performing the motor identification. P1910 can't be
changed while the motor identification with P1900 is active (P1900 = 2 or 3). When the identification is
finished P1910 is set to 0. When choosing the setting for measurement, observe the following:
"with parameter change"
•
means that the value is actually adopted as P0350 parameter setting and applied to the control as well
as being shown in the read-only parameters below.
"without parameter change"
•
means that the value is only displayed, i.e. shown for checking purposes in the read-only parameter
r1912 (identified stator resistance).
The value is not applied to the control.
Dependency: No measurement if motor data incorrect.
P1910 = 1: Calculated value for stator resistance (see P0350) is overwritten.
Note: See P1900
r1912[0] Identified stator re-
sistance [Ω]
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 leak-
age inductance
Displays identified total dynamic leakage inductance.
Index: [0]
r1925[0] Identified on-state volt-
age [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 per-
centage or a hexadecimal value.
Where:
hexadecimal 4000 H ==> P2000 (e.g.: USS-PZD)
•
percentage 100 % ==> P2000 (e.g.: analog input)
