Caution On Homing - Panasonic minas a4 series Instruction Manual

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 deceleration. Take the positioning action and homing action into account when
you set put acceleration/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
