314 RELAY OUTPUT 2 FUNCTION 2345 (2.3.9)
Table 122: Output signals via DO1 and output relays RO1 and RO2
Setting value Signal content
0 = Not used Out of operation
Digital output DO1 sinks the current and programmable relay (RO1,
RO2) is activated when:
1 = Ready The AC drive is ready to operate
2 = Run The AC drive operates (motor is running)
3 = Fault A fault trip has occurred
4 = Fault inverted A fault trip not occurred
5 = Frequency converter overheat warn-
ing
The heat-sink temperature exceeds +70 °C
6 = External fault or warning Fault or warning depending on parameter ID701
7 = Reference fault or warning
Fault or warning depending on parameter ID700 - if analogue refer-
ence is 4—20 mA and signal is <4 mA
8 = Warning Always if a warning exists
9 = Reversed The reverse command has been selected
10 = Preset speed (Applications 2)
10 = Jogging speed (Applications 3456)
The preset speed has been selected with digital input
The jogging speed has been selected with digital input
11 = At speed The output frequency has reached the set reference.
12 = Motor regulator activated
One of the limit regulators (e.g. current limit, torque limit) is activa-
ted.
13 = Output frequency limit 1 supervision
The output frequency goes outside the set supervision low limit/
high limit (see parameters ID315 and ID316 below).
14 = Control from I/O terminals (Appl. 2)
14 = Output frequency limit 2 supervision
(Applications 3456)
I/O control mode selected (in menu M3)
The output frequency goes outside the set supervision low limit/
high limit (see parameters ID346 and ID347 below).
15 = Thermistor fault or warning (Appl.2)
15 = Torque limit supervision (Appl.3456)
The thermistor input of option board indicates motor overtempera-
ture. Fault or warning depending on parameter ID732.
The motor torque goes beyond the set supervision low limit/high
limit (parameters ID348 and ID349).
