Explanation
Calculation
BZ
(Block Zero) stop point
AZ
(Axis Zero Point) axis zero point
= BZ + a
PZ
(Project Zero Point) project zero point
= AZ + b
SLN
(Software Limit Negative) software end position negative
= AZ + d
SLP
(Software Limit Positive) software end position positive
= AZ + f
TP/AP
(Target Pos./Actual Pos.) target position/actual position
= PZ + c = AZ + b + c
a
Offset BZ to AZ (fixed)
EXCM-30: 1.4 mm
EXCM-40: 2.0 mm
b
Offset AZ to PZ
c
Offset PZ to TP/AP
d
Offset AZ to SLN
e
Working stroke
f
Offset AZ to SLP
