General
On the PL-series DC Drive, several parameters are not writable via the serial communications port. This is due to internal limitations of the drive software. The affected parameters are listed below.
You should review the following list to ensure that using the serial port will not cause you problems. Note that fitting a speedy board to the drive and using Ethernet will avoid these limitations
