Hi Craig

I have attached the Norwin drive manual. The plate on the servo's reads:

MT30H4-33
C.STALL: TORQUE 2.1nm
MAX RPM 4000
130v
37a
Tacho 9.5
G90-1582

Thought I had a manual for motors will have another look.

Cheers
Mick

Hi Craig

Norwin are still repairing the drives as I had one repaired a year or so ago. Only cost about £100 (May have been lucky). I think it would be nice to use the servo's and existing drives but after further thought it really makes no sense. At some point in the future maybe not this year someone will need those servo's and drives to fix a machine and probably pay decent money. So I think replacement with steppers is the way I will go.

If I was to go for ordinary steppers without encoders is there any particular brand you would recommend? There loads available all over the net but what do you buy?
I looked at the Smooth stepper and found a company in the Uk that has them. Obviously that still needs a breakout board so need to take that into account and what to use? The Cs Labs  CSMIO/IP-M 4  is around £270 and doesn't require BOB.

Really want to get this one right. The last conversion was poor to say the least.

Cheers
Mick

Hi Craig

Thanks for your reply. Haven't really looked at going out and buying new servo motors and drivers due to cost. Was trying to utilize the original servos if it was a better option. Did think that using the servo steppers would cure loosing steps. Did a conversion a few years ago and never got it right. Very limited speed and threading was never very good.
What would you recommend on a cheaper step and direction controller?

Cheers

Hi All

Looking for some advice regarding keeping original servos and doing a total upgrade and using Leadshine servo steppers. I have a Denford Senior which has a fanuc ot control. A fault occurred about a year ago but never got to the bottom of it. Decided to do something with it now. Don't really want to throw money at such an old control system.

Considering two options : Option 1 keep the original Sem Mt30 Servos along with the Norwin 2110 drives and use a CS Labs CSMIO/IP-A capable of 0 to 10v for the drives.
                                     Option 2 Try and sell the servos and drives and use appropriate Leadshine Servo stepper motors along with a CS labs CSMIO/IP-M.

Seen some good reviews on the forum about Cs Labs products and would really appreciate any comments.

Many Thanks
Mick

Ok thank you.

Will call Norwin to confirm. What do you think of the CSMIO-IP-A.  Unfortunately the DSPMC/ip is out of my price range. What would be a good breakout board to use?

Cheers

Thanks for the reply.

There are a few with analog outputs. They all seem to be +/- 10v. I think the Norwin drive needs +/-15v.
Would this be right?

Cheers
