Safety
Always observe the safety information and warnings in the documentation of
the product and of the other components used.
Before mounting and installation work, switch off supply voltage and secure it
against being switched on again. Only switch on the supply voltage again when
mounting and installation work is complete.
Never remove or insert a plug connector when the motor controller is powered.
Observe the handling specifications for electrostatically sensitive devices.
Only enable the controller if the drive has been professionally installed and fully
parameterised.
Do not carry out repairs on the device. If defective, replace the device.
Do not loosen any screws except for the 4 screws on the housing cover.
Warning
Danger of burns from hot housing surfaces.
Touching the motor 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.
Make sure that personnel cannot touch the motor housing.
Inform operating and maintenance staff about the possible hazards.
Let the drive cool down to room temperature before maintenance work.
Warning
Rapidly rotating motor shaft with high torque.
Clothing, jewellery and hair can be caught and wrapped around the shaft. People
can be injured as a result.
Make sure that clothing, jewellery or hair can
not
be caught by the rotating
motor shaft.
Ensure that clothing fits tightly.
Personnel with long hair must wear hair nets.
Caution
Rapidly 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.
Note
Gas formation with fire risk.
If cleaning agents make contact with the hot surface of the motor, gases can
form and ignite.
Prior to cleaning work, let the drive cool down to room temperature.
Pay attention to the instructions for use of the cleaning agent.
1.1 Use for intended purpose
The product is intended for driving and controlling electromechanical drives.
The product is intended for installation in a machine.
Use exclusively:
– In perfect technical condition
– In original status without unauthorised modifications; only the expansions
described in the documentation supplied with the product are permitted
– Within the limits of the product defined through the technical data
– In an industrial environment
The product is intended for use in industrial environments. Outside of industrial
environments, e.g. in commercial and mixed-residential areas, actions to suppress
interference may have to be taken.
1.2 Intended use of the STO function
The STO function (safe torque off ) in accordance with EN61800-5-2 is intended to
shut down the torque of the integrated motor. The STO function prevents unexpec
ted start-up of the integrated motor. The STO function may only be used in applica
tions in which the specified safety characteristics suffice.
Safety characteristics
The product’s STO function fulfils requirements for the following characteristic
safety values:
– PLd/cat.3 in accordance with ENISO13849-1 (Performance Level/PL)
– SIL 2 in accordance with EN61800-5-2 (Safety Integrity Level/SIL)
– SIL CL2 in accordance with EN62061 (Claim Limit/CL)
The achievable safety level depends on the other components used to implement
the safety function.
To protect against unintended motor start-up, the controller of the product must
be activated via the connection [X6] with the category required for the application
in accordance with ENISO 13849-1, e.g. via an external safety relay.
Training of specialized personnel (requirements for staff )
The product may only be commissioned by an electrotechnically qualified person
who is familiar with the topics:
– installation and operation of electrical control systems
– applicable regulations for operating safety-engineering 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 specified diagnostic
coverage, the status of the acknowledgment contact must be evaluated by the control
system every time the STO function is requested. If a potentially dangerous malfunction
is recognised during the diagnostics, appropriate measures must be taken to maintain
the safety level.
Note
The device cannot detect a cross circuit in the input circuit by itself.
If required, use a safety relay with cross-circuit detection.
1.3 Foreseeable misuse of the STO function
The following foreseeable misuses are not approved as intended use:
– Bridging of the STO function
– Applications where switching off can result in hazardous movements or conditions
Note
The STO function must not be used as the sole safety function for drives that are
subject to permanent torque or force (e.g. suspended loads, vertical axes).
