5.2 System structure
The servo drive CMMT­AS is a 1­axis servo drive. Depending on the product vari­
ant, the following components, which are necessary for standard applications, are
integrated into the device or into the cooling profile of the device:
–
Mains filter (guarantees immunity to interference and limits conducted emit­
ted interference)
– Electronics for intermediate circuit voltage conditioning
– Output stage (for motor control)
– Braking resistor (integrated into the cooling element)
– Brake chopper (switches the braking resistor in the intermediate circuit, if and
when required)
– Temperature sensors (for monitoring the temperature of the power module
and of the air in the device)
– Fan in cooling profile (depending on product variant)
The servo drive features a Real­time Ethernet interface for process control. Vari­
ous bus protocols are supported depending on the product design (EtherCAT, Eth­
erNet/IP or PROFINET).
The device can be parameterised via a PC using either the Real­time Ethernet
interface or the separate standard Ethernet interface.
Festo recommends use of servo motors, electromechanical drives, lines and
accessories from the Festo accessory programme.
