4.2 System structure
The servo drive CMMT-AS is a 1-axis servo drive. Depending on the product
variant, 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 emis-
sions)
– Electronics for DC link voltage conditioning
– Power stage (for motor control)
– Braking resistor (integrated into the cooling element)
– Brake chopper (switches the braking resistor in the DC link circuit, if and when
required)
– Temperature sensors (for monitoring the temperature of the power module and
of the air in the device)
– Fan in the cooling profile (depending on product variant)
The servo drive features a real-time Ethernet interface for process control. Var-
ious bus protocols are supported depending on the product design (EtherCAT,
EtherNet/IP or PROFINET).
The device can be parameterised via a PC using either the real-time Ethernet
interface or the separate standard Ethernet interface.
Festo recommends use of servo motors, electromechanical drives, lines and
accessories from the Festo accessory programme.

The CMMT-AS-...-MP product variant supports several bus protocols.
The following options are available for setting the protocol:
– automatic detection by the CMMT-AS-...-MP
5
– Configuration in the CMMT-AS plug-in
– direct specification via SW1 to SW3
