3.23.1 26-** Analog I/O Option MCB 109
3 3
The Analog I/O Option MCB 109 extends the functionality
®
of VLT AQUA Drive FC 200 Series adjustable frequency
drives, by adding a number of additional, programmable
analog inputs and outputs. This could be especially useful
in control installations in which the adjustable frequency
drive may be used as decentral I/O, obviating the need for
an outstation, and thus reducing cost. It also provides
flexibility in project planning.
NOTICE!
The maximum current for the analog outputs 0–10 V is 1
mA.
NOTICE!
Where Live Zero Monitoring is used, it is important that
any analog inputs not being used for the frequency
controller, i.e., being used as part of the building
management system decentral I/O, should have their Live
Zero function disabled.

It is also possible to read the analog inputs, write to the
analog outputs and control the relays, using communi-
cation via the serial bus. In this instance, these are the
relevant parameters.

Setting of on-board Real Time Clock.
The analog I/O option incorporates a real time clock with
battery backup. This can be used as a backup of the clock
function included in the adjustable frequency drive as
standard. See parameter group 0-7*, Clock Settings.
The analog I/O option can be used for the control of
devices such as servos or valves, using the extended
closed-loop facility, thus removing control from the
existing control system. See 3.18 Parameters 21-** Extended
Closed Loop. There are three independent closed-loop PID
controllers.
