1718Figure 8. Motion Tab SMC35 Programmable Indexer Disks
Included with the DPD72351 is the SMC35 Programmable Indexers Disks.  These
disks contain all of the software needed to run the indexer via a PC.  Also included
in the disks are examples programs that can be downloaded into the indexer.  This
software requires  a minimum system of a 486/66MHz processor with 8Mbytes of
RAM and Windows 3.1. Running the Setup.exe from disk 1 of the SMC35
Programmable Indexer Disks will install the software into the...

1920PROGRAMMING
COMMANDSCommands are sent to the DPD72351 by a computer, dumb terminal,  or
handheld terminal.  These commands must be sent in ASCII by a RS232 or
RS422 communications format.  RS232 is used most commonly by computers. 
Commands are made up of one or two letters, possibly followed by one or more
numbers.  All letters are upper case 8-bit ASCII characters with the most
significant bit ignored.  All numbers are ASCII sent with the most significant digit
first. Spaces can be imbedded with no...

2324COMMAND DICTIONARY
A  (2 to 127)  The ACCELERATION command controls the time that the motor
will take to move from base speed to maximum speed. The higher the value, the
slower the motor will accelerate.  The default value is 5.
B  (50 to 3500)  The BASE SPEED is the speed at which motion starts and
stops.  It is entered directly as the number of steps per second.  This is also the
stepping rate in the Fast Jog Mode.  Not all base speeds will be possible.    On
the computer, if you enter B2455, and...

2526G  (no value)  The GO command causes the motion to start in the direction last    34 = 2 + 32
specified.  This command will move the motor the number of steps given by the
N command or to the absolute position given by the P command.  This is one of
three ways to start motion; the other two are the H command and the S
command.
H  (0 or 1)  The HOME command starts the controller searching for Home in the
direction last set.  Motion will start immediately after a terminator , is supplied.

only one axis at a time may be addressed with this command.  The POLL
command is especially useful in debugging a program.
