Solved: Re: Is motion app necessary ?

Servodude · ‎03-07-2022

Hello,

We are thinking of a simple application

1x ctrlX core with PLC app

2x ctrlx drive

It is a simple point-to-point positioning. The drives are not syncronized and do not run on the same time.

The idea is to set drives in drive-controlled positioning mode.

This means basically that sequence is in the PLC and the drives are controlled through the input and output words.
In otherwords setting a homing, start, error reset bit etc to control the drives and in return bits telling ready, in position etc.

For this simple application is the motion app needed?

Best regards

Hello dude,

like in the past with our Indradrive it is also possible with ctrlX DRIVE to use operating modes with drive internal interpolation for application as mentioned by you. With these opmodes you can control the drive directly out of your PLC or an App without a motion axis.

Therfore you can use operation mode "drive-controlled positioning" or the simple "drive-internal interpolation"

1. Drive-internal interpolation

Use S-0-0259.0.0 (velocity), S-0-0260.0.0 (acceleration) and S-0-0359.0.0 (deceleration) to configure the behaviour.

As soon as you send a new target positon to S-0-0258.0.0 the drive will start positioning.

2. Drive-controlled positioning

Use S-0-0282.0.0 (position command value), S-0-0259.0.0 (velocity), S-0-0260.0.0 (acceleration) and S-0-0359.0.0 (deceleration) to configure the behaviour.

Use S-0-0346.0.0 (position control word) to start or interupt the movement.

This op mode can also be used for a more advanced motion when using sequential block mode.

Best regards

Thanks,

so to be 100% clear that I have understood it correcly, with a ctrlX Core it is not necessary to install the motion app, but only required to install the PLC to control the ctrlx Drives in one of the mentioned op modes?

best regards

You are right.

But also have in mind this requires more effort and system knowledge (i.e. parameters) when controlling a drive from PLC, because you can not use the motion FBs.

Best regards.
