3.1 General data
The CMMS-ST stepping motor controller is a fully digital 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 fieldbus 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 parameterisation possible.
