Try reversing  the encoder in the plugin, see screenshot.

Your servo drives should only be enabled when Mach is in control. If they are moving when Mach is in Reset or fully closed then you do not have the servo drives controlled properly.

You can either use the enables in Mach itself or use the ones in the CSMIO plu8gin (Misc I/O page)

Can you give me the picture where i can find the configuration for enable the drivers ....exemple i would connect all my drivers to I/O 3 on csmio

It will depend on what signal your servo drives expect for their enable. If it is simply a positive 24v signal then you could just connect any output to the drive and configure that as an enable in Mach or CSMIO plugin. You can link all drives to the same output if you wish as long as the current draw isnt higher than the max output of the CSMIO (250mA if I recall)

i will probably use the relays    because my SON (enable ) need to connect to LG (GND) of my drivers .... i will use 4 relays each for one drive connected in parallel  to IO3 of csmio

You can use a single relay to do that, just have all of the drives enable inputs to one side of the contacts and the LG to the other.

Afraid I have never slaved a motor  so cant really help except to say it sounds like you have tu8ning issues with the slaved motor. If the motor/drive are exactly the same as the other motor then try setting the PID exactly the same and see if that helps.

Hi hood

I +- finished my CNC  ... but i have a problems with a limit switches ..... when the cmc go and touch the limit switch  ...the cmc stop ... and i can not run it in opposite side  ....i need to remove my limit switch  (manually ) to move my cnc .

thanks

If you hit a limit switch with the CSMIO you have to jog off via the keyboard, MPG mode does not allow you to jog off.

i think it is my problem     form user guide csmio
what is the solution ?   the HV disable my motors if limits is activated ?

10.9.5.2 HV Enable
In this place you can – for any CSMIO/IP con-
troller output – assign a function of main voltage activation (e.g. for servo drives). In many alarm situations like e.g. E-STOP signal activation, additionally main supply disconnection it may increase security level.
Output defined as „HV Enable” will be active during normal work of CSMIO/IP controller, in case of any alarm situations, such as limit switch or E-Stop touch, the signal will become inactive.

When you hit an E-Stop can you take Mach out of Reset (steady  green LED rather than flashing red)?

non every  time  it detect the switch limit and go into reset

Title: Re: tuning motors

Go to settings page and choose the Auto Limit Override option and see if that allows you to take Mach out of Reset.
