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. Lock to
prevent accidental reactivation. Only switch on the supply voltages again when
Mounting and installation work is complete.
– Never remove or insert a plug when the power is switched on.
– Observe the handling specifications for electrostatically sensitive devices.
– Do not enable the closed-loop controller until 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 motion path while the system is
connected to a source of electric power.
• Make sure that nobody is in or able to reach into the operating area of the
connected actuators.
• Secure the danger zone with suitable protective measures, e.g. guards and
warnings.
CAUTION
Personal injury and material damage
Falling loads in the event of a power failure or when the power supply is switched
off when the drive is installed in an inclined or vertical position.
• Secure loads by external safety measures (e.g. toothed latches or moveable
bolts).
CAUTION
High temperatures on the housing surfaces.
Touching the surface may cause a person to be startled and to react in an uncon-
trolled manner, causing subsequent secondary damage.
• Protect the product to prevent accidental touching.
• Before touching the product, e.g. for mounting or installation: allow the motor
controller to cool down to room temperature.
2.1

Intended use of the CMMO-ST

The motor controller CMMO-ST is intended for controlling the following drives
with Festo 2-phase stepper motors:
– Positioning systems in the Optimised Motion Series (OMS) with Festo axis/
motor units.
– Configured drives (rotary/linear):
– Festo axes, e.g. EGC, DNCE, DGE
– User-defined axes
• Observe the specified standards as well as the regulations of the trade asso-
ciations, 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, actua-
tors).
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 by the technical data
– within the specified service life of the switching elements for the safety func-
tion
– as an installed device in a control cabinet
Use outside the control cabinet is possible if all of the plugs are connected and all
unused interfaces are sealed with protective caps.
2.2

Intended use of the STO function

The STO function ("Safe Torque Off") in accordance with EN 61800-5-2 is intended
to shut off the torque of a motor connected to the CMMO-ST. The STO function
prevents an unexpected start-up of the connected motor. The STO function should
only be used for applications for which the stated safety characteristics are suffi-
cient.
Safety characteristics
The STO function of the CMMO-ST satisfies the requirements for the following
safety characteristics:
– PL e/Cat. 3 in accordance with EN ISO 13849-1
– SIL 3 in accordance with EN 61800-5-2
– SIL CL 3 in accordance with EN 62061
The achievable safety level depends on the other components used to implement
a safety function.
To protect against unintended motor start-up, the motor controller must be acti-
vated via the connection [X3] with the category required for the application in
accordance with EN ISO 13849-1, e.g. via an external safety relay unit.
Qualification of the specialist technicians (requirements for staff )
The product may be placed in operation only by a qualified electrotechnician, who
is familiar with:
– The installation and operation of electrical control systems.
– The applicable instructions for operating safety engineering systems.
– The applicable regulations for accident prevention and occupational safety.
– The documentation for the product.
Diagnostic coverage (DC) for the safety function
The diagnostic coverage depends on the integration of the motor controller in the
control chain as well as the implemented diagnostics measures. If a potentially
dangerous malfunction is recognised during diagnostics, appropriate measures
must be taken to maintain the safety level.
NOTICE
The motor controller cannot detect a cross circuit in the input circuit by itself.
• If required, use a safety relay unit with detection of shorts across contacts.
