Actual signals and parameters 209
AUTO Automatic fan control. The fan is switched on when the drive
is modulating. After the drive has stopped, the fan stays on
until the temperature of the drive has dropped below 55 °C.
The fan then remains switched off until either the drive is
started or the temperature increases above 65 °C.
If the control board is powered from an external 24 V power
supply, the fan is switched off.
0
ON Fan always on 1
18 FREQ IN & TRAN
OUT
Frequency input and transistor output signal processing.
1801 FREQ INPUT
MIN
Defines the minimum input value when DI5 is used as a
frequency input. See section Frequency input on page 133.
0Hz
0…16000 Hz Minimum frequency 1 = 1 Hz
1802 FREQ INPUT
MAX
Defines the maximum input value when DI5 is used as a
frequency input. See section Frequency input on page 133.
1000 Hz
0…16000 Hz Maximum frequency 1 = 1 Hz
1803 FILTER FREQ
IN
Defines the filter time constant for frequency input, ie the
time within which 63% of a step change is reached. See
section Frequency input on page 133.
0.1 s
0.0…10.0 s Filter time constant 1 = 0.1 s
1804 TO MODE Selects the operation mode for the transistor output TO.
See section Transistor output on page 134.
DIGITAL
DIGITAL Transistor output is used as a digital output DO. 0
FREQUENCY Transistor output is used as a frequency output FO. 1
1805 DO SIGNAL Selects a drive status indicated through digital output DO. FAULT(-1)
See parameter 1401 RELAY OUTPUT 1.
1806 DO ON DELAY Defines the operation delay for digital output DO. 0.0 s
0.0…3600.0 s Delay time 1 = 0.1 s
1807 DO OFF
DELAY
Defines the release delay for digital output DO. 0.0 s
0.0…3600.0 s Delay time 1 = 0.1 s
1808 FO CONTENT
