105 SrLss Spd Reg Ki
Sets the integral gain of the speed regulator when sensorless motor speed feedback is
used. This value is automatically calculated based on the bandwidth set in Par 106 [Srlss
Spd Reg BW]. Integral gain may be manually adjusted by setting Par 106 to zero. Units
are '/Sec' (per unit torque/sec) / (per unit speed error).
Units:
Default:
Min/Max: /Sec

106 SrLss Spd Reg BW
Sets the bandwidth of the speed regulator when sensorless motor speed feedback is
used. Units are in rad/sec. Bandwidth is also referred to as the crossover frequency.
Small integral time response is approximately 1/BW and is the time to reach 63% of set
point. A change to this parameter will cause an automatic update of Parameters 104
[SrLss Spd Reg Kp] and 105 [SrLss Spd Reg Ki]. To disable the automatic gain
calculation, set this parameter to zero. The maximum limit for this parameter is
determined by Par 354 [Iq Rate Limit], the ratio of Par 8 [Motor Inertia] to Par 9 [Total
Inertia], and Par 107 [SrLss Kp Max].

107 SrLss Kp Max
Places a limit on the maximum value of proportional gain in Par 104 [SrLss Spd Reg Kp],
for use when sensorless motor speed feedback is used. When gains are autmatically
calculated, this parameter is necessary to limit the amplification of noise with increased
inertia.
