2.5.4 "Sensor type 1" Zero search
Sensor type 1 zero search is carried out according to the following illustration.
Zero search position
offset. See description in
other chapter.
Zero search velocity
velocity used during Zero search.
The sign of the specified velocity
defines the zero search direction.
Zero search torque
trip level when the zero position
is reached.
1=active high -1=active low.
The Zero sensor must be connected to the analogue input (AIN), which during Zero
search functions as a digital input. For connection information, see Analogue input, page
70.
2.5.5 "Sensor type 2" Zero search
Sensor type 2 zero search is carried out according to the following illustration.
Zero search position
offset. See description in
other chapter.
Z
velocity used during Zero search.
The sign of the specified velocity
defines the zero search direction.
Zero search torque
trip level when the zero position is
reached.
+1=active high 1=active low.
The Zero sensor must be connected to the analogue input (AIN), which during Zero
search functions as a digital input.
For connection information, see Analogue input, page 70.

When the zero search sensor is activated, the
motor decelerates and starts to move in
the reverse direction with 1/64 of Zero search
Velocity. When the edge of the Zero search
sensor is passed the motor stops and the
zero position is found.

The position is sampled in the exact
position where the sensor was
activated. The motor the decelerates
and moves the reverse distance back
to the position where the sensor was
activated.
