Parameter Descriptions
Hardware Detection :
The trip is issued from the sine and cosine inputs, based on the following nominal values for the resolver :
CARRIER VOLTAGE : 7Vrms
RATIO : 0.5
Software Detection :
The trip is also issued from the sine and cosine inputs. The trigger value used is based on the following formula :
trip level = 0.15 *( CARRIER VOLTAGE * 0.1414 * RATIO * 2.0 )
where
CARRIER VOLTAGE = 7Vrms, RATIO = 0.5 for a standard resolver
0.15 is the trigger value.
RESET LINE COUNT
If TRUE the LINE COUNT X4 diagnostic is reset.
LINE COUNT X4
Diagnostic showing the resolver position with a resolution of 65536 points per resolver division. This diagnostic is set to 0 at
power-up and reset when RESET LINE COUNT is TRUE.
PULLEYBELT RATIO
Set the ratio of Pulley Belt system between the encoder feedback and the motor shaft ( Typically PARVEX Torque Motors ) .
Can be used either for resolver or ENDAT encoder.
Default value is 1 ( feedback mounted directly on the motor shaft )
