General information 

The CMMS-ST stepping motor controller is a fully digital servo positioning controller for 
activating two-phase hybrid stepping motors.  

The CMMS-ST is intended for activating hybrid stepping motors with a maximum current 
of up to 8 A, in particular the MTR-STand EMMS-STseries by Festo.  
The MTR-ST and EMMS-ST series motors without encoders are controlled in an open 
control circuit (open loop). 

The EMMS-ST series motors with encoders are operated in a closed control circuit  
(closed loop). 

The device can be operated via digital and analogue control signals and networked via the 
integrated CAN bus. Other field bus systems can also be implemented via the technology 
module slot. 

The parameterisation tool FCT (Festo Configuration Tool) makes possible simple operation 
and start-up of the servo positioning controller. Graphic depictions and pictograms make 
intuitive parameterization possible.
