8.2.7 Machine zero mode
P212: setting the machine zero mode
="0": MZ equals external initiator rounded with resolver zero & machine zero travel
using 2 reversing initiators.
="1": MZ equals external initiator rounded with resolver zero.
="3": MZ equals external zero pulse
*
="4": MZ equals external initiator rounded with the external zero pulse.
*
="5": MZ equals resolver zero
="6": reserved
="7": MZ equals external initiator (without resolver zero).
="8": MZ equals a limit switch
="10": MZ teach
="11": Machine zero - initiator (without resolver zero) with 2 reversing initiators
P212 becomes valid immediately after a modification.
*
P212=3 & P212=4 is only permitted for COMPAX XX00 and COMPAX XX30.
Function of the machine zero mode
P212 ="0"
Start search direction / initiator side Application
P213: defines the initiator flank of the machine zero
initiator that is being evaluated; i.e. the side
from which the initiator is approached.
P3: the prefix defines the start search direction.
P215: influences the start search direction during
find machine zero.
P29: shifts the actual machine zero in the direction
of the clockwise rotating motor.
P216: sets the limit switch position
(must also then be set if there are no
configured limit switches (P217=0)
Linear movements
P215="0": the motor rotates clockwise when traveling in the positive direction; i.e.
the positive end in the diagram is on the right-hand side.
P212="0": operating mode with reversing initiators; i.e. with 3 initiators.
P217="0": operating mode without end initiators. I1 and I2 act as reversing
initiators during "Find machine zero".
P216="0": the I1 initiator is started by the clockwise rotating motor.
P3 = positive (when P3 = negative, reverses start search direction)
