2. IMPLEMENTATION 
The implementation has been directed under standard version 4.1.0. 
2.1 INDEX RANGE & CHANNEL SELECTION 
All the SDOs described in DS402 standard range from index 0x600 - 0x67FF. However these 
are only for controlling one motor channel. For multi channel controllers the controller should 
be able to accept index ranges for the other channels as well. These index ranges are shifted 
ranges of the abovementioned one as shown below: 
  0x6000 - 0x67FF, for channel 1. 
  0x6800 - 0x6FFF, for channel 2. 
  0x7000 - 0x77FF, for channel 3. 
There are Roboteq motor controllers with up to three channels available. 
2.2 MODES OF OPERATION 
Roboteq Controllers support the following operation Modes: 
A.  Open Loop 
B.  Closed Loop Speed, controls Speed using Speed as feedback. 
C.  Closed Loop Speed Position, controls Speed using Position as feedback. 
D.  Closed Loop Count Position, controls Position. 
E.  Closed Loop Position Relative, controls Position within specific boundaries. 
F.  Closed Loop  Position Tracking, controls  Position within specific boundaries, with 
abrupt transition. 
In order to conform the above operation modes to the operation modes described, the DS402 
modes  of  operation supported by  Roboteq are shown in  Table 1 - Operation Table  1. Any 
other mode described in DS402 standard is not supported by Roboteq controllers.
