Bandwidth:
Cutoff characteristic: –24 dB/Oct
Phase: Nonlinear phase characteristicst
Interpolation: Interpolation can be turned on and off.
Resolver:
The angle of rotation is computed from the carrier signal, sine signal, and cosine
signal.
Supported carrier frequencies: 1 kHz to 20 kHz
Tracking filter band setting:
Maximum measurable angular acceleration:
140000 rps 2 (when the tracking filter is set to 2 kHz)
2
54000 rps (when the tracking filter is set to 1 kHz)
2
1800 rps (when the tracking filter is set to 250 Hz)
2
180 rps (when the tracking filter is set to 100 Hz)
Demodulation of the pulse width modulated (PWM) signal:
The PWM-modulated signal is integrated over the modulation period and converted
into an analog signal.
Reactive power:
The reactive power is computed from apparent power and effective power.
CAN ID detection:
The frame of the CAN bus signal with the specified ID is detected.
Torque:
The torque is computed from the measured frequenvy and the specified coefficient.
Angle difference math:
S1 – S2 (Angle)
Subtract the value (angle) of source channel 2 from the value (angle) of source
channel 1.
3 Phase Resolver:
Calculates the angle of rotation from the two sine signals that are generated from the
detection coil of the 3 phase resolver depending on the angle of the rotor.
Supported carrier frequencies: 1 kHz to 20 kHz
