How to assign a station to external axis

kentz

I have two external axis, but both axis share the same extax value. 

How can i assign them to different external axis values?

Then probably they are hidden parameters.

It is likely the setup of the system is so that there is only one drive unit for the two axis.

Therfor they can never be activated at the same time

I think the only option you have is to totaly rebuild your MOC file. Maybe best if you contact your local ABB representative

SjoLi

in the parameters for motion (MOC) you can  assign a logical axis.

MOC -> Joint -> logical axis  7-12 assign to extax.a to extax.f

6.16.3 Logical Axis

Parent

Logical Axis belongs to the type Joint, in the topic Motion.

Cfg name

logical_axis

Description

Logical Axis defines the axis number as seen by a RAPID program.

Usage

The value of Logical Axis is used by RAPID programs to identify individual axes

in mechanical units.

Two mechanical units can have the same value set for Logical Axis, but then they

cannot be activated at the same time by a RAPID program.

Robots from ABB normally use the values 1-6, while additional axes use 7-12.

Allowed values

A value between 1 and 12.

Hi, SjoLi.

I am pretty new to RS.

How do I change the moc file?

I can see it under controller tab--> configuration editor-->Moc and there's nothing within Joint.

I can't add anything. Do you need write permission or something to do so?

Thanks
