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 the supply voltage and
secure it against being switched on again. Do not switch on the supply voltage
again until all mounting and installation work has been completed.
–
Never remove or insert a plug when the motor controller is powered.
–
Handhabungsvorschriften für elektrostatisch gefährdete Bauelemente ein-
halten.
–
Do not enable the closed-loop controller until the drive has been professionally
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.
2.1
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 industrial environments, e.g. in commercial and residential mixed-use
areas, measures to suppress interference may be required.
2.2
Intended use of the STO function
The STO "Safe torque off" function (Safe torque off) in accordance with
EN 61800-5-2 is intended for use in switching off the torque of the integrated
motor. The STO function prevents unexpected start-up 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 d/cat. 3 in accordance with EN ISO 13849-1 (Performance Level/PL)
–
SIL 2 in accordance with EN 61800-5-2 (Safety Integrity Level/SIL)
–
SILCL 2 in accordance with EN 62061 (Claim Limit/CL)
The achievable safety level depends on the other components used to implement
a safety function.
For protection against unexpected start-up, the product must be actuated via the
connection [X6] with the category required for the application in accordance with
EN ISO 13849-1, e.g. by 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
–
Applicable regulations for operating safety-related systems
–
Applicable regulations for accident prevention and occupational safety
–
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 speci-
fied 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 dan-
gerous 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 are examples of foreseeable misuse and are 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.

Requirements for product use
–
Provide the complete product documentation to the following personnel:
–
the design engineer and the installer of the machine or system
–
the personnel responsible for commissioning
–
Keep the documentation available throughout the entire product lifecycle.
–
Ensure compliance with the specifications in this documentation. Also observe
the information in the documentation for the other components and modules,
e.g. axial kit, gear unit, actuator, lines.
–
Observe all of the legal regulations applicable for the installation site and the
following documents:
–
instructions and standards
–
regulations of the testing organisations and insurers
–
national specifications
For correct and safe use of the STO function:
–
Conduct a risk assessment for your machine.
–
Comply with the specified safety characteristics
