10. Setting the Home Position
10.1 Principle of the Homing Operation
10.2 Fine Control of the Home Position
IA performs homing in the following manner.
(1) The moving direction is determined by the parameters set by the homing command.
(2) The software senses the mechanical end in the homing operation.
(3) The slider reverses direction when this end is reached and the place where the Z phase signal is detected becomes the
reference point.
(4) The slider travels further by an offset amount defined by the parameters and this position becomes home.
(1) Initiate the homing operation and confirm home.
(2) After that, move to the desired home position, check the difference and adjust the parameters (For the E/G controller,
any negative value is not acceptable).
(3) If you allow for ample offset amount the movement range is that much more limited.
If the offset is greater than 1mm, you will have to reset the stroke soft limit.
The number of motor revolutions from the time the slider hits the stopper to when the Z phase signal is generated
is adjusted when the unit is shipped.
The standard value of the backing distance when the slider hits the stopper, reverses and then stops at the home position
is,
10.3 Changing the Home Direction
If you need to change the home direction after the unit is delivered, the move direction parameter must be
changed and you may need to adjust the encoder Z-phase so please contact IAI.
Also, the origin direction can not be changed in your company when it has the double slider.
10.4 Counter Mark Affixation
Make sure to affix the counter mark on the slider and base so
that the origin position can be confirmed.
It is necessary as the reference position when the positional
deviation is confirmed because of the timing belt tooth
missing or in the case of the motor change.
As long as the homing direction is the same, you can make fine adjustments to the home position for each actuator by
changing the parameters based on this value. Adjustments are made as follows:
