I'm also scratching my head on how to e stop the spindle. Is it just a case of cutting the mains power supply with the e stop contactor??

Yes, e-stop cuts power to the servo.

Ideally, e-stop would cut motor power to the servos while leaving the servo control still powered up. Same for the spindle - remove the motor power, but leave the VFD control power on.

This lets you retrieve any error or fault codes from the devices.

If a Servo goes on error, the machine stops anyway, so i can read the error code.

But when I hit E-Stop I want to cut off all high voltage going to the machine for safety reasons.

Its a SCSI 50 pin connector.

Uwe, I am comparing your wiring diagram for the JASD 15002 spindle servo with the one in the JASD manual. Excuse me if I am wrong but I think there was a typo on the pin17 connection should read pin 7. Here's the diagram from the manual.

Pin 7 is for external 24V, Pin 17 to Pin11 for internal 24V.

Hello Uwe, I am bench testing now and have one question. Above you wrote:

"In the Zip is the schematic as PDF and DWG , all JMC manuals / selection guides and the XML file for the drive types to use with Acorn."

What is the XML file used for?

Thanks... Richard

This is a Drivetype file for the wizard.

Uwe

Got it. So you don't need it for a spindle application.

Thank you.
