Contents of this chapter
This chapter gives a short description of the extension module.
Product overview
The FAIO-01 analog I/O extension module expands the analog inputs
and outputs of the drive control unit. It has two bipolar/unipolar
current/voltage inputs and two unipolar current outputs. In the bipolar
mode, the inputs can handle positive and negative signals. In the
unipolar mode, the inputs can handle positive signals only. The way
the drive interprets the negative range of the inputs depends on the
parameter settings of the drive, see the firmware manual.
FAIO-01 has basic insulation against the drive control unit ground,
but together with basic-insulated motor temperature sensors, FAIO-01
forms double insulation. This allows you to measure, for example,
motor winding temperature without a double or reinforced insulation
requirement on the measuring element.
