Direct Data Transmit Parameters

Parameters 911 [SL Tx DirectSel0]…914 [SL Tx DirectSel3] select what direct
transmit data you want to send. The most common settings for these parameters
are:

• 0 “No Data” - No data is selected for that transmit word.

• 1 “SL Multiply” - See details on

Multiply Block on page 183

.

• 2 “Event P0” - Transmits registration value from registration latch 0.

• 3 “Event P1” - Transmits registration value from registration latch 1. Event

P1 is not functional over SynchLink at the time of publication.

• 10 “Event Status” - Transmits the found bits for registration latch 0/1

status.

• 21 “Dir Tx Data” - Use this selection to transmit a parameter. Parameters

965 [SL Dir Data Tx00]…968 [SL Dir Data Tx03] contain the values for
direct data transmitted to SynchLink. When 21 “Dir Tx Data” is selected
the corresponding direct transmit parameter (parameters 965…968)
parameters can be linked to source parameters.

• 22 “Dir Rx Data” - Use this selection to transmit data that was received on

SynchLink straight through.

• 23 “E0 Accum” - Use this selection to transmit Encoder 0 counts directly

through before they enter the feedback control loop. This eliminates the
update delay of the feedback control loop.

• 24 “E1 Accum” - Use this selection to transmit Encoder 1 counts directly

through before they enter the feedback control loop. This eliminates the
update delay of the feedback control loop.
