Application Setup
Procedure: Calibrate sine encoder using ServoStudio2
Currently, ServoStudio2 does not support sine encoder calibration.
Sine encoder and resolver diagnosis
Overview of sine encoder and resolver diagnosis
When working with a sine encoder or resolver, the CDHD2S measures the sine and cosine
signal levels and checks if they are within the specific range. When the signal is out of range, two
faults may occur: r4 and r8.
If these faults occur, sine and cosine signals should be recorded to determine whether they are
valid.
Record signal
Sine and cosine signals can be recorded by special recording drive - internal data. A typical
RECORD (record) command is as follows:
record11000"@ENCSINE"@ENCCOSINE
This command records 1000 samples of sine and cosine values at 31.25µs intervals (based on
the drive rate).
A typical sine encoder recording might look like the figure below.
