X120
Prerequisite for using interface X120:
•
REA 5001 or
•
XEA 5001
Information
Remember that the encoder interfaces can usually evaluate or
simulate several systems (e.g., EnDat® and incremental encoder).
In the parameters enter the particular system that you are
connecting to an interface. Please consult the inverter operating
manual in this case.
Information
Interface X120 is a double interface on option board XEA 5001. The
double interface makes it possible to distribute encoder signals to
other inverters without a great amount of wiring work. This is why
the two sub D connections have the same allocation.
