Safety

– Always observe the safety instructions and warnings in the documentation of
the product and the other components.
– Before mounting and installation work, switch off supply voltage and secure it
against being switched on again. Do not switch on the supply voltage until
mounting and installation work is complete.
– Never remove or insert a plug when the motor controller is powered.
– Handhabungsvorschriften für elektrostatisch gefährdete Bauelemente einhal­
ten.
– Do not enable the closed­loop controller until the drive has been profession­
ally installed and fully parameterised.
– Do not carry out repairs on the device. If it is defective, replace the device.
– Do not loosen any screws except for the 4 screws on the housing cover.
WARNING!
Risk of injury from touching hot surfaces.
Contact with housing can cause burn injuries. This can frighten people and cause
them to act in an unpredictable manner. This can lead to other forms of secondary
damage.
• Avoid unconscious touching of the housing.
• Inform operating and maintenance staff about the possible hazards.
• Before maintenance work: Let the drive cool down to below 40°C.
WARNING!
Fast rotating motor shaft with high torque.
Contact with the motor shaft can cause burn injuries and abrasions.
• Ensure that the rotating motor shaft and components attached to it cannot be
touched.
WARNING!
Gas formation with fire risk.
If cleaning agents come into contact with the hot surface of the drive, gases may
be formed and may ignite.
• Allow the drive cool down to room temperature before starting cleaning.

Intended use

The product is intended for the actuation and control of electromechanical drives.
The product is intended for installation in a machine.
Use exclusively:
– In perfect technical condition
– In original condition without unauthorised modifications; only the extensions
described in the documentation supplied with the product are permitted
– Within the limits of the product defined by the technical data
– in an industrial environment
Outside of industrial environments, measures may need to be implemented for
radio interference suppression, e.g. in commercial and residential/mixed­used
areas.
2.2

Intended use of the STO function

The STO function "safe torque off" in accordance with EN 61800­5­2 is intended
to shut down the torque of the integrated motor. The STO function prevents unex­
pected start­up of the integrated motor. The STO function may only be used in
applications in which the specified safety characteristics are sufficient.
Safety characteristics
The product's STO function fulfils requirements for the following characteristic
safety values:
– PL dl/cat. 3 in accordance with ISO 13849­1 (Performance Level/PL)
– SIL 2 in accordance with EN 61800­5­2 (Safety Integrity Level/SIL)
– SIL CL 2 in accordance with IEC 62061 (Claim Limit/CL)
The achievable safety level depends on the other components used to implement
a safety function.
To protect against unintended motor start­up, the controller of the product must
be activated via connection [X6] with the category required for the application in
accordance with ISO 13849­1, e.g. via an external safety relay unit.
Qualification of the specialist technicians (requirements for staff)
The product may be commissioned only by a person with electrical engineering
qualifications who is familiar with the following:
– installation and operation of electrical control systems
– the applicable regulations for operating safety­related systems
– the applicable regulations for accident prevention and occupational safety
– the documentation for the product:
Diagnostic coverage (DC) for the safety function
Diagnostic coverage is determined by including the product in the control chain
and the measures implemented for the diagnostics. In order to achieve the spe­
cified diagnostic coverage, the status of the feedback contact must be evaluated
by the control system every time the STO function is requested. If a potentially
dangerous malfunction is detected during diagnostics, appropriate measures
must be taken to maintain the safety level.
The device cannot detect a cross circuit in the input circuit by itself.
• If required, use a safety relay unit with detection of shorts across contacts.
2.3

Foreseeable misuse of the STO function

The following examples of foreseeable misuse are among those not approved as
intended use:
– bypassing the STO function
– use in applications where switching off can result in hazardous movements or
conditions.
The STO function is not sufficient as the sole safety function for drives that are
subject to permanent torque or force (e.g. suspended loads, vertical axes).
2.4

Obligations of the operator for the safety function

The implemented safety function must be subjected to a regular and documented
performance test by a specialist during the period of use of the machine.
The frequency of these tests must be determined by the machine operator based
on the specifications of the machine manufacturer.
– Check the EMCA at least once a year.
