Zero Position Programming
Zero position programming is an OTP option that simplifies assembly of a system, as the magnet does not need to be
manually adjusted to the mechanical zero position. Once the assembly is completed, the mechanical and electrical
zero positions can be matched by software. Any position within a full turn can be defined as the permanent new
zero/index position.
For zero position programming, the magnet is turned to the mechanical zero position (e.g. the “off”-position of a rotary
switch) and the actual angular value is read.
This value is written into the OTP register bits Z9:Z0 (see Figure 14) and programmed as described in section 12.
This new absolute zero position is also the new Index pulse position for incremental output modes.
Note: The zero position value may also be modified before programming, e.g. to program an electrical zero position
that is 180° (half turn) from the mechanical zero position, just add 512 to the value read at the mechanical zero
position and program the new value into the OTP register.
