2.2 Overview of CMMO-ST
2.2.1 General properties
– Rotor-oriented control: stepper motor behaves like a servo motor; force control possible, energy-
optimised operation, low heat generation
– Separate load and logic supply (no new homing run required after emergency stop)
– Control cabinet unit, field use in IP40 environments is also possible (with full pin assignment)
– Ethernet interface with integrated web server
– Backup file: includes all parameterisation settings. It can be stored on separate data storage
media. Enables seamless device replacement.
– 7 segment display to indicate device states, errors and warnings
– Internal braking resistor present
– The CMMO is available as an NPN variant (type code CMMO-…-DION) and a PNP variant
(type code CMMO-…-DIOP). This document describes both variants.
– Function “Safe torque off ” (STO):

2.2.2 Commissioning options
The CMMO-ST can be parameterised and commissioned as follows:
– With the integrated web server, using a mechanical drive of the OMS series (optimised motion
series): diagnostics and parameterisation via standard web browser, simple positioning
( section 5.3)
– with FCT, the Festo Configuration Tool: convenient, full function range ( section 5.4)
Control via Ethernet (CVE):
It is possible to start records from a PC programme via the Ethernet interface. However,
in-depth knowledge of programming TCP/IP applications is required for this purpose
( appendix B.1).
2.2.3 Control profiles of the I/O interface
Valve profile (7)
Simple I/O control: Based on the pneumatic valve pilot, 7 position records can be selected directly
through one input each (7 separate inputs). Upon reaching the target position the output correspond-
ing to the input is set (7 separate outputs). The valve profile exclusively supports simple positioning
operation, optionally with reduced torque.
Binary profile (31)
Flexible I/O control: 31 records (plus record 0 = homing) can be addressed via 5 inputs. The binary
profile also enables jogging and teaching, force mode, speed mode and record linking.
A detailed description of these profiles section 5.5.
