3. Ride off of the
HOME sensor HOME
(before the index)
4. Ride off of the
HOME sensor (at the
index moment)
As shown on the diagram above, the drive should extend the active state on the HOME output until it
step on the encoder index. During the tests with ARBAH drive the achieved homing accuracy at
2000mm/min speed and encoder's 10000imp/rev - ranged +/-1 imp. of the encoder.
That detailed homing is useful in practice, because after power failure or E-Stop pressing or any other
incident that causes that we need to re-home, we are sure that there will be no trace in a place
where the process was continued.
Homing algorithm in the CSMIO/IP-S is made in such way, that the base point does not change even
after acceleration and/or speed for the axis changed. It gives the possibility to adjust the acceleration
parameter during the process (requires a temporary stop, configuration parameters change and re-
homing).
You should note that at the moment you back off the HOME switch, the rotor should be turned for
o
min. 15 to the index point, because - if the index would be very close to the Home switch travel back
off point then homing dispersion may occure. In case the back off point and the index are to close,
you have to adjust the HOME switch position. Do not regulate on the encoder!
