3.2.8 Current Segment Time Adjustment – Fig. 3.8 & 3.9
The Time Adjust function allows the time of a segment to be extended or reduced by a value preset in the 't.Adj'
frame – see
Ramp/Soak Profile Control Page. The segment time can be adjusted repeatedly (in preset increments)
while the segment is running, either from the controller faceplate or by a digital signal (assigned in the '
Inc.S' or
'
dEc.S' frames).
Note. Any changes made to the segment time using this function are not saved in the program memory.
At the end of the program, all segment times are reset to their original values.
