OVERVIEW OF BASIC OPERATION MODES
The Indexing Operation Mode allows for different methods for executing the stored functions:
ASCII Serial Mode
PCX Programming Mode
Input/Output Mode
Serial Mode
The serial interface provides a capability that basically is an additional control mode beyond the
three basic control modes (ANALOG, PULSE and INDEXING).
The Serial Control Mode can also be used to execute or program motion functions. The user can
send the execution serial commands from his programming device through the serial interface to
the drive. Common types of programming devices are programmable logic controllers (PLCs)
equipped with BASIC or ASCII communication modules.
In Serial Control Mode, the numeric display indicates an (E.). This control mode is accessible
via the serial connector “A” on the drive and the protocol is based on ASCII characters. To enter
the Serial Control Mode, the digital drive must receive an SC=1 string preceded by an axis I.D.
character if the appropriate DIP switches are set.
The serial interface is always accessible via serial ASCII commands. The difference, as far as
the display is concerned, is that serial commands to initiate motion will be ignored unless the
decimal point after the E is on (E.). If the decimal is on, meaning you are under Serial Control
Mode, then motion initiation from the I/O is ignored. Stop commands from either serial or I/O
are always accepted and additionally, both hardware or software travel limits are going to work if
programmed in the (E) or (E.) modes.
