CS-Lab / Problem in CSMIO IP A configuration
« on: August 02, 2015, 10:07:06 PM »
Hello all,

I am retrofittig one old cnc with csmio ip/a

I started tuning controller. I faced some issue and needs your help

I decoupled motor as i wanted to first make it in my control. It runs fine except couple of strange behave

1) i am getting encoder error - please check encoder connection- when i look at diagnosis screen, encoder value is showing with red flashing value (255 and sometimes 14). When i run motor, values are changing as it should be, motor is in control, movement is as desired then what this error indicates? I couldn't find it in manual

2) during trial, sometimes as soon as i press reset in mach, motor start running at full speed at any direction and trips on pid fault. Then i tried swapping encoder in configuration (not actual) and set it back to original, couple of times doing this made motor working again in control

I faced same issues in both axis where i took trial

3) during trial, first run always shorter then expected. I mean giving 10 mm command makes movement of 7 mm in first run, then onwards it runs 10 mm without any error

Hi guys

Kflop with kanalog or CSMIO/IP-A - which is better? Easier? Less complex for newbies?

General Mach Discussion / Heidenhain scale interpolation
« on: June 30, 2015, 10:07:40 AM »

I have analog drives with tacho connected with drives. Axis have linear encoder- heidenhain scales

Now to use any controller - csmio/ip-a or kflop; i will need some differential signal as a feedback

Heidenhain signals are 11uA signals. I know there are convertor available but i am not able to get those

Can anyone suggest some good economical convertor which can help me in this case?

General Mach Discussion / Servo Tuning help Please
« on: April 01, 2015, 02:48:57 AM »

I am trying to tune one servo
Motor is directly coupled with screw.  2 revolution of motor will make 5 mm movement

Servo motor has techo connected. There is no cpr written. Only 20mVrpm written on name plate

What should i feed to tunning page?

I kept mach steps 140 after lot of trials. Now if i give command from mdi to move 550 mm, my physical movement is around 554/557/555 - varying random and that too in both directions

Please suggest what to do now

I have one old machine Voest Alpine model WNC500

Machine is turning centre, with milling online

Can I use mach for this machine?

General Mach Discussion / Reviving old machine using mach

Hello Friends

I am new here. I am going to revive an old CNC Devlieg using MACH controller. My drives are DC servo drives for Axes and spindle. All are old analog drives. As of now i am not going to replace drives as all drives are healthy.

I am going to use one breakout board for control with PWM to analog convertor for all axis drive

I am also using S7 200. I want to know what control i should use with PLC and what from MACH? Should i use toolchanger program in PLC? or Mach will take care of that?
