CMMO-ST_U L1)
Requirements for operating the product in the USA and Canada in
accordance with certification by Underwriters Laboratories Inc.
(UL).
1) The documentation is enclosed in printed format.
Fig. 1 Documentation on the CMMO-ST
1 Safety
 Observe the safety instructions and warnings in the documentation of the motor
controller and the documentation of the other components used.
 Before mounting and installation work: Switch off the supply voltage. Secure
against accidental reactivation. Only switch on the supply voltage again when
mounting and installation work is complete.
 Never remove or insert a plug connector when the motor controller is powered.
 Observe the handling specifications for electrostatically sensitive devices.
 Only enable the controller if the drive has been professionally installed and fully
parameterised.
 Do not perform any repairs on the motor controller. In the event of a defect:
Replace the complete motor controller.
Warning
Serious injury or damage to components as a result of collisions.
 Make sure that there are no objects in the positioning range while the system
is connected to a source of electric power.
 Make sure that nobody is in, or is able to reach into, the operating area of the
connected actuators.
 Secure the danger zone through suitable safeguarding measures, e.g. guards
and warnings.
Caution
Personal injury and material damage.
Falling loads in the event of a voltage failure or disconnection of the power sup
ply when installing the drive in an inclined or vertical position.
 Secure loads through external safety measures (e.g. toothed latches or mov
able bolts).
Caution
High temperatures on the housing surfaces.
Touching the surface may cause a person to be startled and react in an uncon
trolled manner, with subsequent damages.
 Protect the motor controller to prevent accidental touching.
 Inform operating and maintenance staff about any potential hazards.
 Before touching the product, e.g. for mounting or installation: Allow the motor
controller to cool down to room temperature.
1.1 Intended use of the CMMO-ST
The intended use of the CMMO-ST is to control the following drives with 2-phase
step motors from Festo:
– Positioning systems in the Optimised Motion Series (OMS) with axis/motor units
from Festo
– Configured drives (rotary/linear):
– Axes from Festo e. g. EGC, DNCE, DGE
– User-defined axes
 Observe the specified standards as well as the regulations of the trade associa
tions, the German Technical Control Board (TÜV), the VDE regulations or the
relevant national regulations.
 Observe the limit values for all additional components (e.g. sensors, actuators).
Use the CMMO-ST only as follows:
– In perfect technical condition
– in its original condition, without unauthorised modifications
– within the limits of the product defined through the technical data
– within the specified service life of the switching elements for the safety function
– as an installed device in a control cabinet
Use outside this control cabinet is possible provided that all plug connectors are
connected or are sealed with protective caps.
1.2 Intended use of the STO function
The STO function (“Safe Torque Off”) according to EN 61800-5-2 is intended to
disconnect the torque from a motor that is connected to the CMMO-ST. The STO
function prevents an unexpected start-up of the connected motor. The STO functi
on should only be used for applications in which the specified safety characteri
stics suffice.
Safety characteristics
The STO function of the CMMO-ST fulfils the requirements for the following safety
characteristics:
– PL e/Cat. 3 according to ENISO13849-1
– SIL 3 according to EN61800-5-2
– SILCL3 according to EN62061
The achievable safety level depends on the other components used to implement
the safety function.
To protect against unintended motor start-up, the motor controller must be ac
tivated via the connection [X3] with the category required for the application ac
cording to EN ISO 13849-1, e.g. via an external safety switching device.
Qualification of specialists (personnel requirements)
The product may only be placed in operation by a qualified electrotechnician who
is familiar with:
– installation and operation of electrical control systems
– the applicable regulations for operating safety-engineered systems
– the applicable regulations for accident prevention and occupational safety
– the documentation for the product
Diagnostic coverage (DC) for the safety function
Diagnostic coverage depends on the interconnection of the motor controller with
the control loop system as well as the implemented diagnostics measures.
If a potentially dangerous malfunction is recognised during the diagnostics, appro
priate measures must be taken to maintain the safety level.
Note
The motor controller cannot detect a cross circuit in the input circuit by itself.
 If required, use a safety switching device with cross-circuit detection.

1.3 Possible misuse of the STO function
The following misuses are among those not approved as intended use:
– Bridging of the STO function
– Use in applications where switching off can result in hazardous movements or
conditions.
Note
The STO function must not be used as the sole safety function for drives that are
subject to permanent torque or force (e.g. suspended loads, vertical axes).
The STO function does not provide protection against electric shock, only
against dangerous movements!
2 Requirements for product use
 Provide the complete product documentation to the following personnel:
– the design engineer and the installer of the machine or system
– the personnel responsible for commissioning
 Keep the documentation safe throughout the entire product lifecycle.
 Ensure compliance with the specifications in this documentation. Also comply
with the supplementary documentation for the other components and modules
(e.g. motor controller, circuits, etc.).
 Take into consideration all of the legal regulations that are applicable for the
installation site, as well as the following documents:
– Regulations and standards
– Regulations of the testing organisations and insurers
– National specifications
For correct and safe use of the STO function:
 Conduct a risk assessment for your machine
 Comply with the specified safety characteristics (èChapter 7, Technical data).

6 Commissioning
To commission the CMMO-ST (DHCP server) with Ethernet cable via parameterisati
on interface directly with the computer/notebook (DHCP client) (point-to-point
connection). 2 variants for commissioning:
– Simplified commissioning of positioning systems (OMS) via integrated webser
ver with English-language parameterisation and diagnostics website
(http://192.168.178.1)
– Complete commissioning of positioning systems and of configured drives with
FCT (Festo Configuration Tool)
The complete commissioning process for the motor controller is described
in the manual GDCP-CMMO-ST-LK-SY-… and in the Online Help for the
CMMO-ST plug-in of the FCT software.
The process control of the motor unit is performed by the control interface
with device profile FHPP (Festo Handling and Positioning Profile):
– Informations about the FHPP èDescription GDCP-CMMO-ST-LK-C-HP-...
– Function elements (CODESYS, ...) èwww.festo.com/sp
Prior to integration in the network:
 Do not connect the motor controller to the network as a DHCP server if another
DHCP server is already enabled on the network.
 For inclusion in a network, change the IP configuration of the motor controller
with FCT or webserver.

8.1 7-segments display
The 7-segment display on the CMMO-ST
provides information about the current
operating mode, errors and warnings.
4 characters are always displayed in
succession, followed by a space.
The numbers of diagnostic messages in the Error or Warning categories are coded
in hexadecimal format.
During a firmware update the display
alternates between vertical and horizontal
segments.
The wave function enables a motor
controller to be identified within a network
that has multiple motor controllers.
The point flashes in the display of the
selected motor controller; the motor
controller “nods”.
