Parameter Dictionary Parameters
I/O extension configuration for modules. This parameter is used to configure
the I/O extension feature on plus modules which support it.
For a detailed description of this I/O extension feature, see the Extending Plus
Module I/O application note.
Number of bits to transfer less 1 (e.g., set to 19 to transfer 20
bits).
Set to enable SPI I/O extension feature. Clear for LED/Switch
interface.
Automatically restart transmission if set.
Leave the CS line low after transfer if set.
Clock period (100ns units).
I/O extension transmit data. Data to be transferred over the SPI port is sent
immediately after being written to this parameter.
*Data size is variable dependent on drive configuration. Refer to the Extending Plus
Module I/O application note.
I/O extension receive data. Data received from the SPI port can be read from this
parameter.
*Data size is variable dependent on drive configuration. Refer to the Extending Plus
Module I/O application note.
Encoder sine offset. This is set in A/D units and only used with resolvers and
servo-tube motors. It gives an offset which is added to the encoder sine
signal before calculating position.
Encoder cosine offset. Like 0x18F, but for encoder cosine signal.
Encoder cosine scaling factor. Used by the resolver & servo tube encoder
calculations. This scaling factor is used to adjust the cosine signal amplitude so that
it's the same as the sine signal amplitude.
If set to zero, both the scaling and offsets (0x18F,0x190) will be ignored. If non-zero
the cosine is scaled by N/32768 where N is the value of this parameter.
