External Control of the Drive
Communications Command
When sequencing is in the Remote Comms mode, the sequencing of the Drive is controlled by writing to
the COMMS COMMAND (PREF 95.05).
The COMMS COMMAND parameter is a 16-bit word based on standard fieldbus drive profiles. Some bits
are not implemented in this release (see “Supported” column of the table below).
