6.3.4.3 Angle Accuracy Parameters

The overall angle error represents the relative angular error. Section 6.3.4.3 shows the deviation from the reference line after zero angle definition..

The uncalibrated angular error (ANGERR_NOCAL_DE) is defined as the maximum deviation from an ideal angle without any offset and amplitude mismatch calibration for the VSIN and VCOS differential signals. For single-ended signals, the uncalibrated angular error is denoted by ANGERR_NOCAL_SE .

The single point calibration angular error (ANGERR_RTCAL_DE) is defined as the maximum deviation from an ideal angle after the offset calibration is applied to the VSIN and VCOS differential signals at room temperature (25°C). For single-ended signals, the room-temperature calibrated angular error is denoted by ANGERR_RTCAL_SE .

The dynamic angular error (ANGERR_DYN) is defined as the maximum deviation from an ideal angle with the continuous offset and gain calibration applied to the VSIN and VCOS differential signals. The error is measured at 1krpm and includes the phase error owing to the propagation delay of the AMR outputs.
