Pa1_11 Output Pulse Phase Selection At Ccw Rotation; Pa1_12 Z-Phase Position Offset - Fuji Electric Alpha7 VV User Manual

PA1_11 Output pulse phase selection at CCW rotation

No. Name
Output pulse phase
11 selection at CCW
rotation
The phase of the output pulse of the servomotor is adjusted to the traveling direction of the machine.
Select the phase of forward rotation (CCW rotation) of the servomotor.
The pulse is output at connector CN1 (FFA, *FFA, FFB and *FFB).
 If the reference value is 0
A-phase
B-phase
 If the reference value is 1
A-phase
B-phase

PA1_12 Z-phase position offset

No. Name
Z-phase position
12
offset
The Z-phase output position shifts. The Z-phase output position shifts in the CCW direction by the
specified pulse amount.
This parameter is irrelevant to the rotation direction selection (parameter PA1_04).
The Z-phase used for homing is also the position that is offset with this parameter.

* The position of the key is not always the Z-phase position.
The position of the key is supposed to be the Z-phase position in this explanation.
