1 Safety and requirements for product use
Festo – GDCP-CMMO-ST-EA-SY-EN – 1301a – English 9
1 Safety and requirements for product use
1.1 Safety
1.1.1 General safety instructions
When commissioning and programming positioning systems, the safety regulations in this description
as well as those in the operating instructions for the other components used must be observed.
The user must make sure that nobody is within the sphere of influence of the connected actuators or
axis system. Access to the possible danger area must be prevented by suitable measures such as
shutting them off and warning signs.
Warning
Electric axes move with high force and at high speed. Collisions can lead to serious
injury to people and damage to components.
• Make sure that nobody can place body parts in the positioning range of the axes or
other connected actuators and that there are no objects in the positioning path
while the system is still connected to a power supply.
Warning
Parameterisation errors can cause injury to people and damage to property.
• Only enable the controller if the axis system has been installed and parameterised
by technically qualified staff.
Note
Damage to the product from incorrect handling.
• Switch off the supply voltage before mounting and installation work. Switch on
supply voltage only when mounting and installation work are completely finished.
• Never unplug or plug in a product when powered!
• Observe the handling specifications for electrostatically sensitive devices.

10 Festo – GDCP-CMMO-ST-EA-SY-EN – 1301a – English
1.1.2 Intended use
The CMMO-ST motor controller is used for controlling stepper motors in accordance with the Festo
catalogue, and is especially intended for use with EPCO electric drives.
This description documents the basic functions of the CMMO-ST and the I/O interface.
EPCO drives and additional components are documented in separate operating instructions.
The CMMO-ST and the connectable modules and cables may only be used as follows:
–asintended
– only in an industrial environment
– in perfect technical condition
– in original status without unauthorised modifications (only the conversions or modifications
described in the documentation supplied with the product are permitted)
• Observe the safety instructions and intended use in the documentation for all the components and
modules.
• Observe the standards specified in the relevant chapters, as well as the regulations of the trade
associations, the German Technical Control Board (TÜV), the VDE conditions or relevant national
regulations.
• Observe the limit values for all additional components (e.g. sensors, actuators).
Note
In the event of damage caused by unauthorised manipulation or other than intended
use, the guarantee is invalidated and the manufacturer is not liable for damages.
