Festo — CMMT-AS-C2/3/5/7/12-11A-P3-... — 2021-12e
Product overview
13
–
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 device has separate connections for logic and load voltage supply. The load voltage supply comes
directly from the low-voltage network. The logic supply must be provided by a PELV fixed power supply
(+24 V DC).
The servo drive includes the option of connecting 2 encoders. In addition, the device has 1 switching
output for direct connection of the holding brake in the motor and 1 output for control of an external
clamping unit.
An external braking resistor can be connected instead of the internal braking resistor, if necessary.
The servo drive features a real-time Ethernet interface for process control. Various 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.
If required, the CDSB operator unit can be plugged in at the top of the front panel of the device. The
CDSB displays, for example, diagnostic information as well as setpoint and actual values in plain text.
To enable you to operate several servo drives in a device compound, the DC link circuits of several
devices can be coupled, and the power supplies and I/O signals of the devices can be linked through
cross-wiring. The DC link coupling can increase the energy efficiency of the device compound.
Festo recommends use of servo motors, electromechanical drives, lines and accessories from the
Festo accessory programme.
