Thanks, here is a link to it http://www.sorotec.de/shop/CNC-Contr...anced-PRO.html . Its an Advanced PRO from Benezan electrics. I bought adaptors for the drivers also. This made wiring a lot easier.
Heres the options i had

• Stepper motors, no VFD speed control: 4-5, 7-8

Relay 1 controlled by LPT pin 1, no PWM, current reduction by pin 17, watchdog signal at pin 16


• Stepper motors with VFD and analogue output: 3-4, 5-6, 7-8


Relay 1 on if PWM>10%, PWM at pin 1, current reduction pin 17, watchdog pin 16


• Servo drives and VFD: 4-5. 6-7


Relay 1 at pin 1, PWM at pin 17, no current reduction, watchdog pin 16


• Special mode for Leadshine stepper drives: 4-5, 6-7, 10-11


Relay 1 at pin 1, PWM at pin 17, enable signal instead of current reduction, watchdog pin 16

I used the last one , now i am using the 2nd one.
