Clear Sticky Bits
Command value:
0xB
Number of data bytes:
0
Command byte:
0x0B
Description:
The overcurrent and position error bits in the status byte and the position wrap and servo timer overrun
bits in the auxiliary status byte will stay set unless cleared explicitly with this command.
Save Current Position as Home
Command value:
0xC
Number of data bytes:
0
Command byte:
0x0C
Description:
Causes the current position to be saved as the home position. This command is typically issued to a group
of controllers to cause their current positions to be stored synchronously. The stored positions can then be
read individually by reading the home position.
Add path points
Command value:
0xD
Number of data bytes:
n = 0, 2, 4, 6, 8, 10, 12 or 14
Command byte:
0xnD
Data bytes:
1, 2:
Incremental data for path point 1 (n >= 2)
3, 4:
Incremental data for path point 2 (n >= 4)
…
13, 14:
Incremental data for path point 7 (n = 0xE) or
None Starts execution of path point mode (n = 0)
Description:
The data format of the points is a 2-byte signed value. The most significant byte is the integer part and the
least significant byte is fractional part (1/256 of encoder count). The whole value is added to the desired
position each servo tick. The same value is applied Path Points Buffer counter times, thus forming the
desired frequency between the path points.
No Operation
Command value:
0xE
Number of data bytes:
0
Command byte:
0x0E
Data bytes: None
Description:
The No Operation command does nothing except cause a status packet with the currently defined status
data to be returned.
