7 Incremental interface
Danger of damage to subsequent electronics due to overvoltages caused
by a missing ground reference point!
•
If the ground reference point is completely missing, e.g. 0 V of the power
supply not connected, voltages equal to the supply voltage can occur at the
outputs of this interface.
It must be ensured that a ground reference point is present at all times,
or the system operator must provide appropriate protective mechanisms
for the subsequent electronics.
•
If the input voltage exceeds 30 V, these voltages occur accordingly at the
HTL outputs. This can lead to damage of the output or input circuit of the
downstream processing unit.
Danger of unnoticed damage to the internal electronics, due to
unacceptable overvoltages!
•
If overvoltages of >7 V DC are inadvertently applied at the incremental
analog output signals SIN+, SIN–, COS+, COS–, Ref+ or Ref–, the
measuring system must be checked in the factory.
The measuring system must be shut down immediately
When sending the measuring system to the factory, the reasons and
circumstances relating to the overvoltage must be specified
