General meaning Meaning with the CMMT-AS-...
Attention! Hot surface Metallic housing parts of the device can have high temperatures
during operation. In case of error, internal components can be
overloaded. Overloading of components can result in high temper-
atures and release of hot gases.
Attention! General danger point The touch current in the protective earth connector can exceed an
alternating current of 3.5mA or a DC current of 10mA.
The minimum cross-section of the protective earth connector must
comply with the local safety regulations for protective earth con-
nectors for equipment with high leakage current.
Attention! Dangerous voltage The product is equipped with intermediate circuit capacitors,
which store dangerous voltage for up to 5minutes after the power
supply is switched off. Do not touch power connections for
5minutes after the power supply is switched off.
5minutes (wait) After the power supply is switched off, wait at least 5minutes
until the intermediate circuit capacitors have discharged.

5.2 System structure
The servo drive CMMT-AS is a 1-axis servo drive. Depending on the product variant, the following com-
ponents, which are necessary for standard applications, are integrated into the device or into the cool-
ing profile of the device:
– Mains filter (guarantees immunity to interference and limits line-bound emitted interference)
– Electronics for intermediate circuit voltage processing
– Output stage (for motor activation)
Further information
12 Festo — CMMT-AS-C2/C4-3A-... — 2018-02

– Braking resistor (integrated into the cooling element)
– Brake chopper (switches the braking resistor in the intermediate circuit, as needed)
– Temperature sensors (for monitoring the temperature of the power module and of the air in the
device)
– Fan (dependent on the product variant in the cooling profile)
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 through a PELV power sup-
ply unit (+24VDC).
The servo drive offers the possibility to connect 2sensors. In addition, the device has 1switching out-
put 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.
An Ethernet interface is available for parameterisation through a PC. The type of activations depends
on the product design (e.g.over bus/network, over EtherCAT, EtherNet/IP or PROFINET).
If required, the CDSB display and operating unit can be plugged in on top of the front side of the
device. The CDSB displays, for example,diagnostic information as well as setpoint and actual values
in plain text and permits updating of parameter record and firmware.
For operation of several servo drives in a device compound, the intermediate 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 intermediate circuit coupling can increase the energy efficiency of the device com-
pound.
Festo recommends use of servo motors, electromechanical drives, lines and accessories from the
Festo accessory programme.

The cooling element on the rear side of the device serves to dissipate the heat from internal compon-
ents to the ambient air. The cooling element has one slot each on the top and bottom for mounting the
device on the rear wall of the control cabinet. If a display and operating unit is not required, the upper
area is covered with a blind plate.
The rear side of the device is part of the cooling element. The integrated braking resistor is integrated
in the air duct of the cooling element. The connecting cable for the braking resistor is passed from the
cooling profile, emerging from the top of the cooling profile, and is connected to the connection [X9B].

Servo drive H1 H21) L1 L2 L3
The required minimum lateral distance from neighbouring CMMT-AS devices is thus 2mm
(52mm–50mm).
For adjacent third-party devices, Festo recommends a distance of at least10mm (surface temperat-
ure of third-party device max.40°C). The double counterplug for cross wiring of the connection [X9A]
projects approx.6…7mm over the right side of the device. But this is not an obstacle for arraying
additional CMMT-AS.
7.2 Installation
The servo drive CMMT-AS is intended to be installed in a control cabinet.
The cooling element of the device has one slot each on the top and on the bottom. The device is
screwed vertically and flat to the mounting surface using the two slots.
Assembly instructions
– Use a control cabinet with at least degree of protection IP54.
– Always install device vertically in the control cabinet (mains supply lines [X9A] point upwards).
– Screw device flat to a sufficiently stable mounting surface so that a good heat transfer from the
cooling element to the mounting surface is ensured (e.g.to the rear wall of the control cabinet).
– Maintain minimum distances and installation clearance to ensure sufficient air flow. The surround-
ing air in the control cabinet must be able to flow through the device without hindrance.
– Take into account the required clearance for the wiring (connecting cables of the device are
guided in from above and from the front).
– Do not mount any temperature-sensitive components near the device. The device can become
very hot in operation (switch-off temperature of the temperature monitoringèTechnical data).
– When assembling several devices in a device compound, consider general rules for cross-wiring.
For intermediate circuit coupling, devices with greater power use must be placed closer to the
mains supply.
For assembling to the rear panel of the control cabinet, the cooling element of the servo drive has a
slot on top in the shape of a keyhole and on the bottom in the shape of a simple slot.
Assembly of the servo drive
WARNING!
Danger of burns through hot escaping gases and hot surfaces.
In case of error, incorrect wiring or incorrect polarity of the connections [X9A], [X9B] and [X6A], internal
components can be overloaded. High temperatures can develop and hot gases can be released.
• Have an authorised electrician perform the installation according to the documentation.
WARNING!
Danger of burns from hot housing surfaces.
Metallic housing parts can accept high temperatures in operation. In particular, the braking resistor
installed in the profile on the back side can become very hot.
Contact with metal housing parts can cause burn injuries.
• Do not touch metallic housing parts.
• After the power supply is switched off, let the device cool off to room temperature.
