“Torque” Zero search
Torque
Zero search
is carried out according to the following illustration.
The
Zero search
method using a torque as a reference is a cheap, simple way to find the
mechanical zero position, but please be aware of following critical points.
•
Make sure that the
Zero search
torque is set to a proper value higher than the me-
chanical friction in the system in order to avoid a faulty zero point being found. It is a
good idea to let the motor run in velocity mode with the same velocity and observe
what the actual motor torque is. This value can be observed in the status area in the
right side of the main window. Set the
Zero search
torque to a value 10-20% higher
than the actual torque observed during this procedure.
•
To improve the repeatability precision of the zero point make sure that the mechan-
ical “collision” point is as stiff and well-defined as possible.
When the torque rises higher than the value
specified in the field
the speed will
Zero search Torque
drop to zero. And the actual position is set to the value
specified in
Zero search position.
Zero search
started
Zero search position
is an optional offset.
This position is preset to the position-
counter after the zero point is found.
Zero search
defines the velocity
velocity
used during Zero search. The sign of the
specified velocity defines the zero search
direction.
Zero search timeout defines the maxi-
mum allowed time to find the zero point.
If not found within this time an error bit
is set. The bit is called Zero search timeout.
Zero search
is used as the trip
torque
level when the zero position is reached
