2.2 List of parameters
Description: Displays the rotor time constant.
For separately excited synchronous motors:
Displays the damping time constant to the rotor direction (d axis).
Note: The parameter is not used for synchronous motors.
The value is calculated from the total of the inductances on the rotor side (p0358, p0360) divided by the
rotor/damping resistance (p0354). The temperature adaptation of the rotor resistance for induction motors is not
taken into account.
Description: Displays the damping time constant of a separately excited synchronous motor quadrature to the rotor direction (q
axis).
Note: The value is calculated from the total of the inductances on the damping side (p0359, p0361) divided by the damping
resistance (p0355).
Description: Displays the stator leakage time constant.
Note: The value is calculated from the total of all leakage inductances (p0233*, p0353, p0356, p0358) divided by the total of
all motor resistances (p0350, p0352, p0354). The temperature adaptation of the resistances is not taken into
account.
* only applies for VECTOR (r0107).
Description: Displays the stator leakage time constant quadrature to the rotor direction (q axis).
Note: The value is calculated from the total of all leakage inductances (p0233, p0356, p0359) divided by the total of all
motor resistances (p0350, p0352, p0355).
The temperature adaptation of the resistances is not taken into account.
