MNEMONIC | FUNCTION | TYPE |
PG | Enter/Exit Program Mode | Program Instruction |
DESCRIPTION
When starting program mode, you must specify at what address to enter the program instructions in the program space. Simply type “PG” again when you have finished entering your program commands to go back to immediate mode.
While in program mode, leading tabs, spaces and blank lines are ignored. This allows the user to format a text file for readability, and then download the program to the MDrive by transferring the text file in a program such as IMSTerminal or Hyperterminal. The example given below could be stored in a text file and downloaded. The lines preceded by an apostrophe (‘) are comments and will be ignored by the MDrive Motion Control.
USAGE
PG <address>
EXAMPLE: |
|
PG 100 | ‘Enter program mode, start program at address 100 |
*********PROGRAM********* | |
E | ‘End prgram |
PG | ‘Exit program, return to immediate mode |

MNEMONIC | FUNCTION | TYPE |
PR | Print Selected Data/Text | Instruction |
DESCRIPTION
This instruction is used to output text and parameter value(s) to the host PC. Text should be enclosed in quotation marks while parameters (variables and flags) should not. Text strings and parameters which are to be output by the same PR instruction should be separated by commas. The information being output is followed by a carriage return and line feed unless a semicolon (;) is included at the end of the PR instruction to indicate that the cursor should remain on the same line.
It is important to note that the receive buffer for the MDrive Motion Control is 64 characters, this includes the PR instruction itself, any spaces, text characters, etc. If the buffer length is exceeded ASCII code “OxFF” will echo to the terminal screen.
USAGE
PR <data/text>
EXAMPLE: |
|
PR “Position =”, P | ‘print axis position, 18 characters used |
‘the terminal will display: Position = 1234567
