7.8.5 Tuning settings
P2.8.7.1 Flying Start Options ID1610
b0 =+1= Disable movement to reverse direction
b1 = +2=Disable AC Scanning
b2 = +4=Disable Fly Brake phase
b3 = +8=Use encoder information for frequency estimate
b4 = +16=Use frequency reference for initial guess
b5 = +32=Disable DC scanning for step-up application
P2.8.7.2 Motor Control Options ID1740
B00 =+1= Use switching frequency of 3,6 kHz during flying start if below.
B01 = +2= Analogue output selection 12; torque sign in open loop shows negative on
negative direction on motoring side.
B02 = +4= Enable angle identification in open loop control for PM Motor
B03 = +8= Reserved
B04 = +16= Reserved
B05 = +32=Reserved
P2.8.7.3 Resonance Damping Select ID1760
feature can be used to dampen the constant frequency torque oscillations in the drive
system.
0 Not in use
Only monitoring if Resonance damping frequency > 0,0 Hz.
See FW: ResonanceFrequency and FW: ResonanceAmplitude.
1 Band pass, Speed Error
Oscillation damping with band pass filter from speed error.
2 Band Stop + Band Pass, Speed Error
Oscillation damping with band stop and band pass filter from speed error.
3 Band Pass. Iq Current.
Oscillation damping with band pass filter from Iq Actual.
P2.8.7.4 Resonance Damping Frequency ID1763
Frequency of torque oscillations to be damped in Hz.
P2.8.7.5 Resonance Damping Gain ID1764
The gain for the oscillation damping. This changes amplitude of the compensating signal
used for oscillation damping.
P2.8.7.6 Resonance Damping Phase ID1765
The compensating signal used for oscillation damping can be phase shifted 0 to 360
degrees using this parameter.
P2.8.7.7 Resonance Damping Activation frequency ID1770
Defines the frequency limit when resonance damping is started.
