The PCL6025/6045B have five built in circuits with 28-bit comparators (CMP1 to 5), and can select the
comparison data shown in the table below.
In addition, there are 9 methods for comparison and four responses to choose from when the conditions are
met.
By using the comparators and counters above, you can do the following:
◆
Interrupt output, output comparison results externally, use as an internal synchronous start.
◆
Immediate stop, or deceleration stop of the operation
◆
Automatic speed change during operation
◆
Software limit function
◆
Out-of-step detection for stepper motors
◆
Synchronous signal output
