Stator winding resistance: Stator winding resistance Ru-v of the motor winding in ohm. Enter
only for external motors. The value can be autotuned with the B41 action.
Value range in Ohm: 0.001 ... 10,300 ... 2147483.647
Fieldbus: 1LSB=0,001Ohm; Type: I32; USS-Adr: 02 0D 40 00 hex

Leakage factor: Ratio of leakage inductance to total inductance "Ls" of the motor
NOTE
The default value is sufficient for most motors and applications. Adjustments may become
necessary when an external motor is connected. In such cases the value can be autotuned with the
action B41. However, do not make this adjustment before consulting with STÖBER
ANTRIEBSTECHNIK GmbH & Co. KG.
Value range: 0.010 ... 0,100 ... 0.300
Fieldbus: 1LSB=0,001; Type: I16; USS-Adr: 02 0D 80 00 hex

Magnetic saturation coefficient: The parameter specifies how much the motor is
magnetically saturated at the nominal point. The parameter is important for the control accuracy of
control type VC (B20=2:VC) in the field weakening area.
NOTE
The default value is sufficient for most motors and applications. Adjustments may become
necessary when an external motor is connected. In such cases the value can be autotuned with the
action B41. However, do not make this adjustment before consulting with STÖBER

Integral time lq: Integral time of the current controller for the torque-generating share in msec. A
setting under 0.6 msec causes an integral gain of 0 (corresponds to an infinite integral time).
