12.5.1. Position Ranges
A position is coded by using the binary two’s complement format. According to the positioning commands used and to the chosen
stepping mode, the position range will be as shown in Table 11.
Table 11: Position Range
Command
SetPosition
SetPositionShort
When using the command SetPosition, although coded on 16 bits, the position word will have to be shifted to the left by a certain
number of bits, according to the stepping mode.
12.5.2. Secure Position
A secure position can be programmed. It is coded in 11-bits, thus having a lower resolution than normal positions, as shown in
Table 12. See also the command GotoSecurePosition.

Important Notes:
12.5.3. Shaft
A shaft bit which can be programmed in
counter-clockwise rotation (an outer or an inner motion for linear actuators):
(1)
(2)
• Shaft = 0 ⇒ MOTXP is used as positive pin of the X coil, while MOTXN is the negative one
• Shaft = 1 ⇒ opposite situation.
T
The resolution of the secure position is limited to 9 bit at start-up. The OTP register is copied in RAM as illustrated below. SecPos1 and SecPos0 = 0.
he secure position is disabled in case the programmed value is the reserved code “10000000000” (0x400 or most negative position).
