Mains imbalance.
This output is activated at too high
line imbalance or when a phase is missing in the line
supply. Check the line voltage to the VLT AFD.

320 Terminal 42, output, pulse scaling
(AO 42 PULS SCALE)
Value:
1 - 32000 Hz
✭
5000 Hz
Function:
This parameter allows scaling of the pulse output signal.
Description of choice:
Set the desired value.
321 Terminal 45, output
(AO 45 FUNCTION)
Value:
See description of parameter 319
Terminal 42, Output.
Function:
This output can function both as a digital or an analog
output. When used as a digital output (data value
[0]-[26]) it generates a 24 V (max. 40 mA) signal. For
the analog outputs (data value [27] - [41]) there is a
choice of 0-20 mA, 4-20 mA or a pulse sequence.
Description of choice:
See description of parameter 319
Terminal 42, Output.
