question volatge siemens drive

hello,

Friends,

I have doubt, i am from colombia, we work with 110V, 220V, 440V, but not 165V or 380V, how configure my drive siemens for work with 440V three-phase?

thanks

jorge

Hello

I know I have already responded on this topic, but I have some doubts yet.

I understand it must be connected to 14 and 56. but on the card "7i77"-and also has ENA0 ENA0 +, these are not used?

Still do not understand how to connect the encoder to the card "7i77".

Something more .. about my motor and the spindle drive. I understand that it is also fed to 0 - +10 V, but with respect to the direction of rotation as the drives would understand that is M3 or M4.?

interprets linuxcnc M3 and M4 positive and negative example sends the voltage so?

any help is precious friends, I see that everything is possible now.


thanks

The 7I77s ENAX+ and ENAX- signals are drive enables. Depending on your drive these would be wired differently

For a drive with an active high enable you would wire ENAX+ to the voltage the
drive enable circuit needs (5V,12V, or 24V typically) and ENAX- to the drive enable input.

For a drive with active low enable you would wire ENAX+ to the enable signal and ENAX- to ground

On the 7I77 ENA5 is different in that it can be controlled independently so it is suggested
that analog channel 5 and ENA5 be used for spindle control

Peter,

But always be connected, or in my case would only need GND and AOUT1.

I understand that the board "7I77" analog output 5 is specified for the spindle, but my question is how does the driver must rotate CW or CCW? I looked in my manual but can not find vector drive that defines something that clear.

so my question about "ENAX +" and "ENAX-" if they define the direction of rotation of the motors?

or also only need to connect GND and AOUT5 to control the spindle motor?

Thanks friend

Motor drives almost universally have an enable input
especially analog servo drives for the axis. It is very important
that these enables are connected and work properly as they will
disable drive motion:

1. At startup and shutdown
2. With following errors
3. At watchdog bites due to crashes/hardware faults

The ENAX outputs are not for direction control but enabling and disabling the drive.

Direction on axis drives is controlled by the polarity of the +-10V analog signal.
Some spindle drives work (or can work) this way, and others use a 0 to 10V
speed signal and a separate DIR or CW/CCW inputs.

For spindle drives that use a separate dir or CW/CCW inputs you
must use some free 7I77 or 7I64 outputs to drive these signals.

Peter,

I found in the manual that works the same way as the servomotor. with voltage ranges 0 +-10V.

in this case as I can make it rotate CW and CCW, M3 and M4 code to indicate whether negative or positive voltage commands?

or as I should?

Thank you.
