6.5.5 "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.
The Zero sensor must be connected to a user input
For connection information, see
6.5.6 "Sensor type 2" Zero search
Sensor type 2 zero search is carried out according to the following illustration.
This type of zero search is more precise than the other types of zero search.
The Zero sensor must be connected to a user input. For connection information, see
User Inputs, page 21.
Hint: Make sure the acceleration/deceleration is set to an appropriate value which stops
the motor when the Zero search switch is detected but before mechanical collision.

Zero search position is an
optional offset. See description

Z ero search velocity defines the
velocity used during Zero search.
The sign of the specified velocity
defines the Zero search direction.
Zero search crawl velocity
is
used to "crawl" back to the sensor
edge after it has been detected.
This parameter is only supported
in FW2.08 or newer.

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.
