MN100 Command Summary

Command Command Definition Parameter Function
E Read Position None Returns the position counter.
F Profile Select 0 to 5 Selects the acceleration profile (See Table 4).
G Jog Tap Steps 1 to 255 Set the number of steps per button push.
H Hold 0 or 1 0 - disables synchronized moves between drivers. Execute moves immediately.
1 - enables synchronized moves between drivers. Waits for release command before executing move commands. (Remote)
I Set Mode 0 or 1 0 - absolute mode (default)
1 - incremental mode
K Release None Enables move commands if HOLD is enabled. (Remote)
L Load Count ±8,388,607 Loads the position register with the specified data.
M Move ±8,388,607 Performs an accelerated move generating the specified number of steps. Returns exit code if an error occurred or if the move was terminated by a switch closure.
N Read Count None Returns the number of uncompleted steps.
O Loop None Restart the program from beginning. (Program)
Q Abort Move None Aborts the move in progress. (Remote)
R Read Memory None Returns the program stored in memory.
S Port Status 0 to 2 Returns status of the input ports (port0 or port 2).
U Run Program None Runs the program stored in memory. (Remote)
V Velocity 20 to 20000 Sets the speed in steps/sec.
W Wait None Halts program until input is low. (Remote)
Y Jog Speed 20 to 20000 Sets the speed for jogging (not accelerated).
Z Program Mode None Puts the device in program mode. All subsequent commands are written to memory until <Ctrl-D> is received. (Remote)
? Firmware Revision None Returns the device name and firmware revision. (Remote)
* Poll None Request response from all connected controllers. (Remote)
& Retransmit None Request the MN slave to resend the last message. (Remote)
~ Change Baud Rate 0 to 4 Changes baud rate. Must be sent to all devices simultaneously (address 0) . 0 - 9600, 1 - 19200, 2 - 38.4K, 3 - 57.6K, 4 - 115K. (Remote)
! Configure and Read/Write I/O Port 0 to 3 Controls reading and writing of I/O port.
0 - output at 0VDC (low)
1 - output at 5VDC (high)
2 - input to run program on switch closure (default)
3 - input with interrupt (high to low transition) (Remote)
# Label <text> Marks a point in the program for branching. (Program)
^ Branch <text> Transfers program execution to a line following a # with matching label. (Program)
