- Page 2 Overview INTRODUCTION The SWIFT 100 is a self-contained , single axis, stepping motor controller and drivecard housed on a standard eurocard pcb. It receives instructions via the RS232 link (J10). A second channel (J9) is used for daisy-chaining. There are manual control options using an analogue joystick and/or digital potentiometer.

Page 5: Manual Control
MANUAL CONTROL In addition to software commands for the SWIFT 100, there is also a manual control mode which will allow motion via a joystick or a hand encoder, see commands L1 and L0. Joystick control is invoked by connecting the joystick analogue voltage, which must be between 0 and 5V , to the edge connector input A15. -
Page 6: Inputs And Outputs
--o-- logic 0V This circuit removes the risks outlined in point 1 but not those of point 2. Furthermore, it does not cater for the condition of a damaged opto-isolator. A true break-to-stop circuit can be employed using a special PAL, this may be requested. ---7--- INPUTS AND OUTPUTS Inputs... - Page 7 The commands are ascii characters from the host which must be followed by either a LF, CR or CRLF. The SWIFT 100 will respond to every command, even if it is not understood. For every legitimate command the SWIFT 100 will return a # after executing. Illegitimate commands are are returned an E.
- Page 8 D [n] If n is not specified make current position the coordinate zero. If n is specified then change coordinate system so current position is n. Set motor current (0<=n<=15) approx 40*n mA. NB. DO NOT EXCEED n=4 IN CONTINUOUS USE UNLESS A HEATSINK IS FITTED.
- Page 9 MC n Move n steps at constant speed (see command C). MCA n Move to position n at constant speed. MCL n Move to limit in direction n at constant speed where (n= -1,0,1). ML n Move to limit in direction n with acceleration If n=1 add a newline (LF) (0x0A) to the normal line terminator of carriage return (0x0D).

Page 10: Important Notes
If N=1 (add newline) then \r above is expanded to \r\n ie: carriage return (0x0D) followed by linefeed (0x0A). Further error processing commands: Get length of the error message (no terminator). EM Returns the error message. Returns the error number. Toggles the echoing of the command input and is intended for initial debugging of communications with a single card. -

SWIFT 100. In fact N SWIFT 100 cards may be linked or daisy-chained to form an N axis system. A command prefixed with a number >1 is sent to the nth card in the system ie: Report the position of 2nd card. - Page 12 RS232 9600/4800/2400/1200/600/300/19200 baud 8/7 data bits 1/2 stop bit, on/off parity odd/even parity (if on) XON-XOFF handshaking...
