I recently wanted to run a program by using the EXECUTE command. When I try to do this, I get an error message. Basically, cannot execute because of EXT_IT. This is a C controller FS10 series robot. We do use RPS for signals back and forth from plc to robot. Searching for the error hasn't produced any results. Any help would be greatly appreciated,
EXT_IT input signal

Can you explain this and provide:
- Error code and description.
- Screenshot of error.
- Screenshot of Teach Pendant Status screen.
- Image of TB2 configuration and wiring.
-
The error code was (#213) Cannot execute a program because of EXT_IT. I would have to recreate to get screenshots and unable to do so currently. In AUX. 111 EXT_IT is set to reset.

Can you show the STATUS screen too?
Can you show an image of TB2 terminal rail too?
-
That error usually relates to Aux 111 setting and possibly SLOGIC (1FS/1HS) board being used in the application.
You need to find out which signal is being used by SLOGIC I think and set Aux 111 data accordingly.
You could try turning off RPS and then create a simple test program and try it again.
This would prove it is software rather than hardware related.
Have you got a full file save you could post?

I may try turning off RPS at some point later, not practical at the moment. I did notice in D controllers that the EXT_IT is used as a hold.

Kawasaki Controllers have a dedicated input called external hold which needs to be hard wired:
C Controller on TB2
D Controller on 1KP board X9.
E Controller on 1TR board X9.
Without the hard wired input, motion is not possible permanently.
These are not to be confused with EXT_IT.
In addition to this you have HOLD/RUN switch either on the controller operation panel, or teach pendant (E controller).
Again, whilst in HOLD, will apply brakes/not release brakes restricting motion.
This is applicable across teach and repeat operations.
However, EXT_IT is only used in Repeat mode for external hold purposes, like if supplied from a light curtain or PLC during the process.
It has to be allocated a signal, internal signal in the dedicated input signal function and that signal needs to be permanently high in order for the robot to move, if the signal is lost/low, it will turn off EXT_IT and put the robot into hold (apply the brakes/prevent brakes from being released) but ONLY used in Repeat.
So in short the:
- HOLD/RUN switch is used by the operator to manually place the robot in hold.
- EXT_IT is used by the process to automatically place the robot in hold.

OK. Thanks for all the info.
