Pump and fan control with autochange
scale.
3. 6 Digital output function
Setting value Signal content
0 = Not used Out of operation
Digital output DO1 sinks current and programmable
relay (RO1, RO2) is activated when:
1 = Ready The frequency converter is ready to operate
2 = Run The frequency converter operates (motor is running)
3 = Fault A fault trip has occurred
4 = Fault inverted A fault trip
has not occurred
5 = Vacon overheat warning The heat-sink temperature exceeds +70°C
6 = External fault or warning Fault or warning depending on parameter 7. 2
7 = Reference fault or warning Fault or warning depending on parameter 7. 1
- if analogue reference is 4—20 mA and signal is <4mA
8 = Warning Always if a warning exists
9 = Reversed The reverse command has been selected
10= Multi-step or jogging speed Multi-step or jog. speed has been selected with digital
input
11 = At speed The output frequency has reached the set reference
12= Motor regulator activated Overvoltage or overcurrent regulator was activated
13= Output frequency supervision 1 The output frequency goes beyond the set supervision
Low limit/ High limit (par. 3. 9 and par. 3. 10)
14= Output frequency supervision 2 The output frequency goes beyond the set supervision
Low limit/ High limit (par. 3. 11 and par. 3. 12)
15= Torque limit supervision The motor torque goes beyond the set supervision
Low limit/ High limit (par. 3. 13 and par. 3. 14)
16= Active reference Active reference goes beyond the set supervision
limit supervision Low limit/ High limit (par. 3. 15 and par. 3. 16)
17= External brake control External brake ON/OFF control with programmable de
lay (par 3. 17 and 3. 18)
18= Control from I/O terminals External control mode selected with pr. push-button #2
19= Frequency converter Temperature on frequency converter goes beyond
temperature limit supervision set supervision limits (par. 3. 19 and 3. 20)
20= Unrequested rotation direction Rotation direction of the motor shaft is different from the
requested one
21 = External brake control inverted External brake ON/OFF control (par. 3.17 and 3.18),
output active when brake control is ON
22= Analog input limit supervision The level of selected analog input goes beyond the
set supervision low / high limit (par. 3. 29 and par. 3. 30)
23—26 = Not in use
27 = Autochange 3 control Control signal for drive 3 in autochange system
28 = Auxiliary drive 1 start Starts and stops auxiliary drive 1
29 = Auxiliary drive 2 start Starts and stops auxiliary drive 2
30 = Auxiliary drive 3 start Starts and stops auxiliary drive 3
Table 6-3a Output signals via DO1
3. 7 Relay output 1 content
Setting value Signal content
0-22 = Same as parameter 3.6
23—25 = Not in use
26 = Autochange 1 control Control signal for drive 1 in autochange system
27 = Autochange 4 control Control signal for drive 1 in autochange system with
I/O-expander option
28 = Auxiliary drive 1 start Starts and stops auxiliary drive 1
29 = Auxiliary drive 2 start Starts and stops auxiliary drive 2
30 = Auxiliary drive 3 start Starts and stops auxiliary drive 3
