B–63610EN/01
204
D When bit 6 (ESI) of parameter No.4950=0
Six M code from M a to M(a+5) are used for half–fixed angle
positioning, when a is the value of this parameter.
D When bit 6(ESI) of parameter No.4950=1
Set the start M code in this parameter, and set the number of M codes
in parameter No.4964. Then b M codes from Ma to M(a+b–1) are
used for half fixed angle positioning.
The table below indicates the relationship between the M codes and
positioning angles.
M code Positioning angle
Example: Positioning
angle when q = 30_
Mα θ 30°
M (α+1) 2θ 60°
M (α+2) 3θ 90°
M (α+3) 4θ 120°
M (α+4) 5θ 150°
M (α+5) 6θ 180°
L L L
M (α+n) (n+1) θ
NOTE
q represents the basic angular displacement set in
pamrameter No.4963.
4963
Basic angular displacement used for spindle positioning using M code
[Data type] Word
[Unit of data] deg
[Valid data range] 1 to 60
This parameter sets a basic angular displacement used for half–fixed
angle positioning using M codes.
4964
Number of M codes for specifying a spindle positioning angle
[Data type] Byte
[Unit of data] Integer
[Valid data range] 0, 1 to 255
This parameter sets the number of M codes used for Half–fixed angle
positioning using M codes.
As many M codes as the number specified in this parameter, starting with
the M code specified in parameter No.4962, are used to specify half–fixed
angle positioning.
Let a be the value of parameter No.4962, and let b be the value of
parameter No.4964. That is, M codes from Ma to M (a+b–1) are used for
half–fixed angle positioning.
