Caution on Homing Operation
• In homing action by using the host controller, stop position might not be stabilized if
the origin input (Z-phase of the encoder) is entered while the motor is not decelerated
enough after the proximity input is turned on. Set up the ON-positions of proximity input
and the position of origin point, considering the necessary pulse counts for decelera -
tion. Take the positioning action and homing action into account when you set put ac -
celeration/deceleration time with parameter, since this affect these action as well.
For the details of homing, observe the instruction manual of the host controller.
• Example of Homing Action
Proximity dog on... .Decelerates at an entry of the proximity input, and stops at an entry
of the first origin input (Z-phase)
Proximity dog off... .Decelerates at an entry of the proximity input, and stops at an entry
of the first origin input (Z-phase) after the input is tuned off
