Parameter Descriptions
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 converter,
that is, being used as part of the building management system decentral I/O, should have their live zero-function
disabled.

Table 3.29 Relevant Parameters
It is also possible to read the analog inputs, write to the analog outputs, and control the relays, using communication via
the serial bus. In this instance, these are the relevant parameters.

Table 3.30 Relevant Parameters
Setting of on-board real time clock
The analog I/O option incorporates a real time clock with battery back-up. This can be used as back-up of the clock function
included in the frequency converter as standard. See chapter 3.2.8 0-7* Clock Settings.
The analog I/O option can be used for the control of devices such as actuators or valves, using the extended closed loop
facility, thus removing control from the building management system. See chapter 3.19 Parameters: 21-** Main Menu -
Extended Closed Loop. There are 3 independent closed-loop PID controllers.
