Resolver Mode
Selecting ‘Mode 3’ as the mode of operation on the conguration screen sets the simulator module into resolver
mode. The bank controls for this mode are outlined below:
Zone 1 - Shows the method of operation for the “Set Position in Degrees” control shown in Zone 2. It will set the
scale to -180 to 180 degrees, or to 0 to 360 degrees - whatever is suitable for you application.
Zone 2 - This shows the main method of controlling the output of the bank:
• The top slider “Maximum Output Voltage (V) [VSUM]” controls the maximum output voltage.
• The second slider “Set Position in Degrees” sets the rotation within a range of either -180 to 180 degrees or 0
to 360 degrees as selected in the Zone 1 option.
• Note; if you double click on the rst slider it will reset the “Set Position in Degrees” slider below it.
Zone 3 - These are some of the auxiliary functions available for controlling the bank, these enable the manipulation
of Rotational speeds, iterations, Loss of Signal (LOS) and Frequency Read / Write functionality.
• “Write Frequency” - Sets the frequency value from the adjacent text box.
• “Read Frequency” - Reads the current frequency value and sets it in the adjacent text box.
• “Null Offset” - Functionality is disabled in the Resolver mode, hence it is greyed out.
• “Set LOS Threshold” - This button reads the value from the adjacent text box and uses it as the threshold
value used for Loss of Signal (LOS) detection.
• “Poll LOS (Off)” - This button will toggle the LOS functionality on or off. The adjacent box; “Bank 1 Input
Signal” will change colour to green when in operation and change to red when the LOS threshold has been
exceeded.
