List of parameters
r1926[0...2] Identified effective valve lockout time / t_lock_valve id
Access level: 4
Can be changed: -
Units group: -
Min
- [µs]
Description: Displays the identified effective valve lockout time.
Index: [0] = Phase U
[1] = Phase V
[2] = Phase W
r1927[0...2] Identified rotor resistance / R_rotor ident
Access level: 4
Can be changed: -
Units group: -
Min
- [ohm]
Description: Displays identified rotor resistance (on separately excited synchronous motors: damping resistance).
Index: [0] = Phase U
[1] = Phase V
[2] = Phase W
p1959[0...n] Rotating measurement configuration / Rot meas config
Access level: 3
Can be changed: T
Units group: -
Min
-
Description: Sets the configuration of the rotating measurement.
Bit field: Bit Signal name
00 Encoder test active
01 Saturation characteristic identification
02 Moment of inertia identification
03 Re-calculates the speed controller parame-
ters
04 Speed controller optimization (vibration test) Yes
Dependency: Refer to: F07988
Note: The encoder is only tested if the rotating measurement with encoder is selected (p1960 = 2).
The following parameters are influenced for the individual optimization steps:
Bit 00: None
Bit 01: p0320, p0360, p0362 ... p0369
Bit 02: p0341, p0342
Bit 03: p1400.0, p1458, p1459, p1460, p1462, p1463, p1470, p1472, p1496
Bit 04: Dependent on p1960
Bit 05: p0391, p0392, p0393, p1402.2 only for induction motors
p1960 = 1, 3: p1458, p1459, p1470, p1472, p1496, p1400.0
p1960 = 2, 4: p1458, p1459, p1460, p1462, p1496, p1461, p1463
The identification of the q leakage inductance can only be carried out for unloaded motors or motors with a low load
(load approx. 30% below the rated motor torque). Only then is a current controller adaptation (p0391 ... p0393)
parameterized if the q-leakage inductance under no-load conditions is at least 30 % higher than the total leakage
inductance (p0356, p0358).
