Description
WARNING
Before installing and commissioning, please read these safety instructions and warning
carefully and all the warning labels attached to the equipment. Make sure that the warning
labels are kept in a legible condition and replace missing or damaged labels.
This equipment contains dangerous voltages and controls potentially dangerous rotating
mechanical parts.
Non-Compliance with Warnings or failure to follow the instructions contained in this manual
can result in loss of life, severe personal injury or serious damage to property.
Only suitably qualified personnel should work on this equipment, and only after becoming
familiar with all safety notices and maintenance procedures contained in this manual.
The successful and safe operation of this equipment is dependent upon its proper handling,
storage, installation, operation and maintenance.
National safety regulations are also applicable.
Procedure of encoder commissioning
The encoder commissioning differs slightly for HTL and TTL encoder. The following table
gives an overview about the single steps depending on the type of encoder.
