Information on EMC-compliant installation
A mains filter is integrated into the device. The mains filter fulfils the following
tasks:
–
Guarantees the device’s immunity to interference
–
Limits the conducted emissions of the device
The device fulfills the requirements of the relevant product standard EN 61800-3
with suitable installation and wiring of all connecting cables.
The category that the device fulfils is dependent on the filter measures used and
the motor cable length. The integrated mains filter is designed so the device fulfils
the following categories when operated as an individual device:
CMMT-AS...

If set-up and commissioning are performed by a professional with the neces-
sary experience for setting up and commissioning drive systems, including
their EMC aspects, category C2 devices can be used in the first environment
(residential area).
–
For operation of category C2 devices, limit values for the harmonic currents
in the network (EN 61000-3-2 or EN 61000-3-12) apply, depending on the
connected load of the machine. Please check whether this is the case for your
facility/system.
–
Category C3 devices are intended for use in the second environment only
(industrial environment). Use in the first environment is not permitted.
This product can generate high frequency interference, which may make it neces-
sary to implement interference suppression measures in residential areas.
In practice, the combination of the components used and their properties influ-
ence the achievable length of the motor cable

STO connection example
The safety sub-function STO (safe torque off) is triggered by an input device that
makes the safety request (e.g. light curtain).

4 Drive axle
Information on the sample circuit
The safety request is passed on to the servo drive on 2 channels via the inputs
#STO-A and #STO-B at the connection [X1A]. This safety request results in the
2-channel switch-off of the driver supply to the servo drive’s power output stage.
The safety relay unit can use the STA diagnostic output to monitor whether the
safe status has been reached for the safety sub-function STO.
SBC connection example
The safety sub-function SBC (safe brake control) is triggered by an input device
that makes the safety request.

example) of the clamping unit
Information on the sample circuit
The safety request is passed on to the servo drive on 2 channels via the inputs
#SBC-A and #SBC-B at the connection [X1A].
–
The request via the input #SBC-A switches off power to the signals BR+ and BR-
at the connection [X6B]. This de-energises and closes the holding brake.
–
The request via the input #SBC-B switches off power to the signal BR-EXT at the
connection [X1C]. This shuts off power to the control of the external clamping
unit. The clamping unit closes.
–
The safety relay unit monitors the SBA diagnostic output and checks whether
the safe status has been reached for the safety sub-function SBC.
