Analog inputs on the I/O extension board
The I/O extension board has an additional analog input. A signal type and function
must be selected for the analog input. The measuring range is scaled for the signal
selected by setting a defined upper and lower limit. (ðSection8.10.2,Page118)
NOTE
The parameter values and value ranges/units entered are mutually dependent. This
is why the first step in parameterising the frequency inverter is always to specify the
applicable value range and units (3-11). If the value range or unit is subsequently
changed, all dependent parameters must be checked for correctness again.

Relay outputs on the I/O extension board
The I/O extension board has one volt-free (NO/NC) relay and five volt-free (NO) relays.
The function of the relays can be parameterised via the control panel.
