3. SPECIFKATIONS /MELSEC-A
(d) M code
Specifies an "M" code relevant to that position address. (range: 0
to 255)
The code should be set to 0 if it is not required.
During interpolation positioning, M codes are given individually
for the X and Y axes. (X-axis M code, buffer address = 46. Y-axis
M code, buffer address = 346.)
(2) Positioning speed
Specifies the speed at which the next position is to be approached.
POINT I
bfore operation, the parameter zpeed limit is checked and if
the positioning rpeed exds the speed limit value, the
parameter speed limit value is used.
Positioning speed for linear interpolation
During linear interpolation positioning, the speed set for the axis
with the furthest to travel takes precedence and the speed of the
other axis is derived as follows.
(Short travel axis speed)
- (short travel distance)
- (long axis 'peed) x (long travel distance)
An example of this is given in Fig. 3.20 which uses the following
data:
X Axis Y Axis
Parameter set value
: speed limit value
50KPLS/sec
20KPLS/sec
Positioning data set value
: positioning speed
50KPLS/sec
POKPLS/sec
To move from point A (address 0, 0) to point B (lwkp, 200kp),
X-axis travel is less than Y-axis travel so Vy = 50kp/s has precedence.
X-axis positioning speed = 50 x - =
200
loo 25KPLS/sec
(This speed exceeds the speed limit value which is ignored in thiscase.)
