Type into the parameter box ‘azer’ this is the servo voltage measurement.
Adjust the phase shifter on the horses head till you hit
the maximum negative output voltage on ‘azer’. The
negative voltage, shown above, is the head rotating anticlockwise.
Note down the voltage in section 4.8 of the build record, the build record is filled in mV so -0.313 is -313mV.
Change the servo loop ga
in ‘slgn’ from 5 to 4 and note down the voltage again. Repeat with ‘slgn’ set at 3 and
2.
Adjust the phase shifter on the horses head till you hit the maximum positive output voltage on ‘azer’. The
positive voltage, shown below, is the head rotating clockwise.
Note down the voltage in section 4.8 of the build record, the build record is filled in mV so 0.318 is 318mV.
Change the servo loop gain ‘slgn’ from 5 to 4 and note down the voltage again. Repeat with ‘slgn’ set at 3 and
2.
