9-24 Applications
In mode #32, only two inputs are available for step transitions.
When the Step Value parameter;
= 0,TB3 terminal #22 is selected
= 1,TB3 terminal #23 is selected
When an input step is executed it will command the Step Speed until
the associated TB3 input is true.
When the associated input goes high, the Control will move to the
next step.
Figure 9.11- Input Step Transitions
Motor Speed P81
The example in Figure 9.11 shows a profile sequence utilizing Input
Mode #31 to control transitions from one step speed to the next.
Since there are 16 steps and a maximum of 6 inputs available for use,
multiple steps can reference the same digital inputs.
Note: When two steps reference the same input you must make
certain they are not adjacent to each other. Note that step 1 and step 7
are both utilizing the same input terminal #19.
For Example: If Step 1 and Step 2 referenced the same input, the
profile control would command Step 1 speed until it saw the input go
true. Upon entering Step 2, it would see the same input high and
immediately (12.5 ms) go to Step 3.
Using Mode #32
Digital input mode #32 duplicates the function of the first three bits of
the Profile Enable command parameter #235 to determine the
command state of the Profile Control. It is best to clear the Profile
Enable command parameter #235 when controlling Profile
operation via input mode 32 to avoid unwanted interactions.
The three profile control TB3 inputs are or’ed with the Profile Enable
command parameter #235 to determine the command state of the
Profile Control.
