3.6.2.5 Digital Output (Transistor)
When using the device’s default configuration, control signal terminal 8 will
be configured as an analog output (AO).
It can be set to work as a digital output instead (DO) with parameter P-25:
Table 13: Control signal terminal 8 (DO)
Transistor output DO uses control signal terminal 8 to switch the device’s
internal control voltage (+24 V) as a digital signal (1 = High). The maximum
permissible load current is 20 mA.

Signal
1 = High (+24 V)
Description
0 RUN Enable (FWD/REV)
1 Ready Ready for operation. No fault signal
2 Actual value =
Setpoint value
The output frequency (f-Out) or speed is equal to the setpoint value (REF).
3
Error (Fault) Fault (not ready).
4 f-Out ≧ P-19 The output frequency (f-Out) is greater than or equal to the value set in P-19
(RO1 upper limit).
5
I-Out ≧ P-19 The output current (I-Out) is greater than or equal to the value set in P-19 (RO1
upper limit).
6
f-Out < P-19 The output frequency (f-Out) is less than the value set in P-19 (RO1 upper limit).
7 I-Out < P-19 The output current (I-Out) is less than the value set in P-19 (RO1 upper limit).
10
Not Enable No enable signal (FWD/REV)
11 Actual value ≠
Setpoint value
The output frequency (f-Out) / speed is not equal to the setpoint value (REF).
Digital output DO: Accuracy ≧ 1% relative to maximum value
