However, everything has its pros and cons. So what are the disadvantages of servo drives?  They are 

certainly more expensive - how much, it depends what kind of stepper and servo drives you compare. 
There are e.g. stepper motors controllers that cost 800 USD and there are some other that cost 40 USD 
(with the same power!).  Generally we can conclude that  the servo motor + drive package is more 
expensive.  Other disadvantage of the servo drives is necessity for PID controllers tuning and wiring that is 
more complicated. That will be the end of the disadvantages. Great advantage of the servo drives is that - 
thanks to the feedback - the servo drive indicates the overload and positioning error. When the CSMIO/IP-
M receives this signal it immediately stops the axes. In the stepper motors there is no feedback like this, 
so even if one of the axis becomes overloaded it will not keep the set trajectory, but the machine will 
continue the work – but not follow the desired trajectory breaking the same entire processed detail. 

In sum – we recommend the servo drives. Their disadvantages are negligible in comparison to the 

benefits they offer. Please note that the servo drive can have much lower nominal torque than holding 
torque of the stepper motor. When we compare the 3Nm stepper drive and 3Nm servo drive – the price 
difference may be significant. However, if we compare the 3Nm stepper drive with the 1Nm servo drive, 
the price difference is not so big.  

Practice shows that sometimes - mechanically identical machines are sold in two versions, with 3Nm 

stepper and 1Nm servo drives. The machine with the stepper motor reaches a max 7,5m/min feed rate and 
0,1g. acceleration. The machine with the servo drive reaches 20m/min feed rate and 0,4g. acceleration. If 
we add the feedback, which was mentioned before, further comparing is pointless. 

The choice is in your hands of course, in some solutions the stepper motors are adequate and work 

very well. Thanks to perfectly precise STEP signal timing of the CSMIO/IP-M controller the stepper motors 
behave much better then when controlling from e.g.  the LPT port. We can use a higher stepper division, so 
the motors will work quieter, smoother and they get higher revs by reducing the resonance.
