3.5 Encoder Safety Precautions for Installation, Operation and Maintenance
•
The ATM60/ATM90/KHK53 encoders must only be fitted or main-
tained when free from voltage. Consequently, for any electrical or
electronic devices, machine and system parts linked to installa-
tion, operation or maintenance, the voltage must previously have
been switched off. Also check that they are voltage-free.
•
Cabling, earthing, screening and overvoltage protection are of
particular importance.
•
Check whether switching off devices, machines or system parts
causes dangers.
•
If necessary, place warning signs to prevent unauthorised per-
sons from entering the danger area.
•
The correct functioning of safety features shall be checked (e.g.
emergency stop).
•
EMC-compliant earthing and screening must be performed with
particular care, to ensure satisfactory operation of the devices.
•
The safe assembly of all components must be checked prior to
switching back on.
•
Avoid impacts on shaft and collet.
•
Programs which frequently use Explicit Messages, to write pa-
rameters to the EEPROM (non-volatile memory) of the encoders,
should be avoided. This could significantly reduce the lifetime.
•
During commissioning of the encoders via a configuration tool,
there must be no connection to a running network.
