Block

Mask

The OP7160EX1 Resolver Out is based on the basic resolver which is a two-pole resolver. The Resolver Out block is used to control the resolver.

This block has the following properties and features:

Possibility to use 2 resolvers per block.
Real-time adjustments of the speed, amplitude (carrier, sin and cos), frequency (carrier), and offset (sin and cos).
Carrier selects between an internal carrier and an external carrier.

Controller Name	Bind this block to an OpCtrl OP7160EX1 block by entering the same 'Controller Name' as specified in the OpCtrl OP7160EX1 block. The OpCtrl OP7160EX1 block controls the initialization of the settings of one specific OP7160 card in the system.
DataIn port number	Enter the index of the DataIn port to be controlled by this block, in the range [1:32].
Slot info	This non-editable parameter displays the physical location of the analog output channels related to the selected DataIn port, as obtained from the parsing of the configuration file.
Number of resolver signals	The block can use between 1 and 2 resolvers. To use 2 resolvers, it is required to set the number of resolvers in the block parameters and to use a 2:1 multiplexer before sending the data into each respective data input.
Carrier Select Mode	The user can select to use an internal carrier or an external carrier. Internal Carrier: When the resolver is set in this mode, the internal exciter is configured via a generated carrier from the FPGA. External Carrier: When the resolver is set in this mode, the external carrier is taken via an analog input port of the FPGA board.

Speed	Set the speed of the simulated rotor. The value is represented in Hz. Range of values: -20000 to 20000.
Car.Amp	Carrier amplitude if no external exciter is used. The value is represented in Volts. Range of values: 0 to 15.
Car.Freq	Carrier frequency if no external exciter is used. The value is represented in Hz. Range of values: 0 to 95000.
Sin.Amp	Sine of the modulated amplitude. The value is represented in Volts. Range of values: 0 to 15. Due to hardware limitations, the product of Car.Amp and Sin.Amp should be less than 15.
Sin.Bias	Sine offset. The value is represented in Volts. Range of values: -15 to 15.
Cos.Amp	Cosine of the modulated amplitude. The value is represented in Volts. Range of values: 0 to 15. Due to hardware limitations, the product of Car.Amp and Sin.Amp should be less than 15.
Cos.Bias	Cosine offset. The value is represented in Volts. Range of values: -15 to 15.

The Status output returns the following values:

Value	Description
0	No error.
-1	Block could not be matched with an OpCtrl OP7160EX1 block (check the 'Controller Name' value), or OP7160 card initialization problem.
-2	Internal memory initialization problem.
