Problems with my rv m1 project

Post by ali_jamal » Tue 25 Dec , 2012 16:29 pm

hello everyone,

i hope someone can help me with my problems cause they are killing me.
i have a RV M1 mitsubishi robot, movemaster drive unit and am using denfords robot communication software.
1. the robot gives an error every time i would upload to it positions
2. the robot would also send an error when i upload a program evetho i would have uploaded the same program before without any problems
3. the most important problem is the following
this is an example of a program i wrote
10 MO 1
20 MO 2
30 OB +3
40 ED

NOW isnt the robot supposed to follow this program line by line, and when it finishes these movements send an output signal through bit 3, and then end the program. because in my case it doesnt, the minute i run the program and output signal is sent!!!!

Enter as much information about your CNC hardware and software as you can - it makes it easier for everyone to know what you're talking about then.

If this was all working OK in the past, my guess is that communication to the robot is getting corrupted.
Has anything changed ? Can you try another RS232 cable ?
Have you got the RVM1 manual ?
I was able to download it from here: ... =2&sstr=RV
The service manual may help with finding the fault.

Does this help for setting up DIP swithches on the RV-M1.

Ensure that the rear silver toggle switch in the Robot control box (PC Control) is DOWN

1. The terminator for Data transmission from the drive unit through the RS232 interface
Upper position CR+LF
Lower position CR

2. Selects whether to check if the contents of the RAM data are retained upon power up
Upper position Check is performed
Lower position Check is not performed

3. Selects the type of I/O card used
Upper position Type A16 or B16
Lower position Type A8 or B8

4. Selects whether or not to set, change, or delete the reference position data in the Cartesian co-ordinate system
Upper position Enable
Lower position Disable

5. Selects whether to enable either the drive unit front control switches or external signals for running the program while type A16 or B16 I/O card is being used
Upper position External signals
Lower position Front control switches

6. Selects whether to enable the ENT key on the teaching box to release Robot brakes
Upper position Disable
Lower position Enable

7. Not used

8. Selects whether to turn ON or OFF the buzzer
Upper position Buzzer On
Lower position Buzzer Off
