WARNING
The safe motor feedback system may be used only within the limits of the prescribed
and specified technical data, dimensions and tolerances of the dimensional drawings
and operating conditions, and the specified tightening torques must be complied with.
If used in any other way or if alterations are made to the device – including in the
context of mounting and installation – this will render void any warranty claims directed
to SICK AG.
The motor feedback system must be mounted and adjusted exactly in accordance
with the specifications of the installation instructions. Every faulty installation or faulty
adjustment of the encoder can impair the specified functions and data; partial restric‐
tion or a total failure of the specified safety functions cannot be ruled out in individual
cases.
WARNING
If stimuli near the resonance frequency (resonance point > 1,100 Hz) cannot be reliably
ruled out in the application, suitable tests must be carried out for the entire drive sys‐
tem before commissioning the system. Suitable corrective measures must be installed.
WARNING
Violations of the specified accuracy of the position value in the vicinity of the resonance
frequencies can occur due to physical restraints. If the mechanical stimulation in the
vicinity of the resonance frequencies has a very high amplitude, faults or failures of the
specified safety functions can occur. We recommend avoiding operation in the vicinity
of the resonance frequencies or at least limiting the amplitude.
The safe motor feedback system may be mounted, put into operation, checked,
maintained, or used only by qualified safety personnel. A qualified person
is someone who has taken part in adequate technical training
•
has been instructed by a machine operator in machine operation and the applica‐
•
ble safety guidelines and
can access these operating instructions.
•
WARNING
The supply voltage must be generated from PELV systems (EN 50178). The motor
feedback system conforms to protection class III in accordance with EN 61140. If the
supply voltage is not generated from PELV systems, the user must take other measures
to ensure safe disconnection for live parts.
WARNING
Use only temperature sensors with doubled or reinforced insulation because there is no
galvanic separation of the temperature sensor in the motor feedback system.
The power supply unit current used for the motor feedback system must be limited to
a maximum continuous current of 1 A, either by the power supply unit itself or using a
fuse.
