Isel Router with KEB S4 Drives

Hello guys , i have started some new projects on some old isel routers. I have some problems whit this KEB drives and dont know why .

I got encoders working in mesa but the analog voltage dot work . It just enables and i can fill the drive been stift . But wont move . Its posible this drive is a digial one . I attach the manual maybe we can get some sugestion .

As far as I can tell from the manual, that drive can do analog velocity mode but needs to be programmed properly
(the LF parameters)

do you have the Keypad/display module?

yes i have the programing module on the drive . What parameter you mean on the display or internal . I can see it has a rs232 interface its possible the parameter is edit in the PC

i cant find any sentting on analog in parameters . I can be torque ?

At the minimum you need to set LF2 = 4
This sets the drive into analog +-10V velocity mode

You probably also have to set all the accel and jerk limit parameters to maximums (or disable if possible)

was this drive used with a CNC machine?


It seems to be a drive for a elevator

PCW first post is wrong on the manual we have S4 not F4 for that i was not finding LF parameter

All the drives are from a isel router and we want to change to linux as its old system . We have enable the drive and i can see in linux the encoder but as it is in torque i cant drive it from a 7i77

You can use torque mode with a 7i77. The loop is a little harder to tune, but it works.
Both my servo machines run torque-mode (8i20 drives).

There is any exemple of torque conf ? its a different configuration on ha?

No, it looks exactly the same. The proportions of P, I, D and FF in the PID control loop will be different, but they are different for every machine anyway.

There is the option of using nested control loops (with a speed control loop controlling torque and a position control loop controlling the speed control loop) and that is something I intend to experiment with. but it isn't necessary to make a working machine.
