Speed change using the comparator]
When the comparator conditions are met, you can use the function which changes the operation data to
the values stored as pre-register data. This function is used to change the speed when a specified
position is reached.
Also, comparator 5 has a pre-register function, and can be specified for use in changing the speed at
specified positions. In this case, use the "Pre-register set command (4Fh)," to specify several sets of
speed data.
If the speed change data (data used with set commands) are left in Pre-registers 1 and 2 when the
current operation completes (Example 1), or if the speed change data is left in Pre-register 1 and some
next operation data exists in Pre-register 2 (Example 2), the PCL will ignore the speed change data and
shift the data in the pre-registers.
Then, in Example 2, the PCL will start the next operation after shifting the data in the pre-registers.
