2.3.5 Analogue output function
This parameter selects the desired function for the analogue output signal.
See the table on page 8 for the parameter values.
Description of parameters
Signal content
Out of operation
Relay output RO1 and expander board
programmable relays (RO1, RO2) are activated
when:
The frequency converter is ready to operate
The frequency converter operates (motor is running)
A fault trip has occurred
A fault trip not occurred
The heat-sink temperature exceeds +70°C
Fault or warning depending on par. 2.7.2
Fault or warning depending on par. 2.7.1
- if analogue reference is 4—20 mA and signal is <4mA
Always if a warning exists
The reverse command has been selected
A preset speed has been selected
The output frequency has reached the set reference
Overvoltage or overcurrent regulator was activated
The output frequency goes outside the set
supervision low limit/high limit (see parameters
2.3.12 and 2.3.13 below)
Selected control place (Menu K3; par. 3.1) is "I/O
terminal"
The thermistor input of option board indicates
overtemperature. Fault or warning depending on
parameter 2.7.19.
Parameters 2.7.22 – 2.7.24
Pump 1 control, parameters 2.10.1 – 2.10.7
Pump 2 control, parameters 2.10.1 – 2.10.7
Pump 3 control, parameters 2.10.1 – 2.10.7
The relay energizes according to settings of
parameters 2.3.14 – 2.3.16.
