D/S Synchro / Resolver Select
As
required, write a “11” or “00” (Synchro = 11; Resolver = 00) to each corresponding channel bit pair,
representing a channel commanded output format, of the
Synchro/Resolver
register.

D/S Torque Receiver Select
When selected, channel will be subjected to an automatic control algorithm which minimizes torque receiver
power draw. Applies only to the single channel modules.
Normal = “0”; Torque Receiver = “1”

D/S Trigger Source Select
May be used during implementation of D/S rotation. When triggered, the D/S channel will commence rotation.
Triggering may be initiated via “internal” software command (
D/S Start Rotation
register)
or via “external’ signal
application (see pin-out).
Internal = “0x29”; External = “0x28”

D/S Trigger Slope Select
May be used during implementation of D/S rotation when

register i
s set for “external”.
For rotation trigger on positive slope, set the corresponding channel bit to "0" in the
Trigger Slope Select
register.
For negative slope, set the bit to "1"

D/S Module Power Enable
The
D/S Module Power Enable
register is utilized for module channel output/power control. Set the bit,
corresponding to either channel, to enable the power output stage of the D/S channel(s). “1” = Enable; “0” =
Disabled. For dual channel modules, writing a “1” to either or both channel bits will enable and turn the output
stage power “on”. To disable, or turn off power to the output stage, all channels (both) bits must be set to “0”.
Initialized default is “00”.
