Data Sheet
13.5.1. 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.

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.

13.5.2. 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:
(1)
T
he secure position is disabled in case the programmed value is the reserved code “10000000000” (0x400 or most negative position).
(2)
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.

13.5.3. Shaft
A shaft bit which can be programmed in
OTP
or with command
SetMotorParam
,
defines whether a positive motion is a clockwise or
counter-clockwise rotation (an outer or an inner motion for linear actuators):
Shaft = 0
MOTXP is used as positive pin of the X coil, while MOTXN is the negative one
Shaft = 1
