188 Actual signals and parameters

Group 18: Freq in & tran out
This group defines the frequency input and transistor output signal processing.
1707
OVERRIDE REF
Selects the source of the override reference.
1 = CONSTANT – Selects a preset frequency or speed for the override. The frequency
value is defined by parameter 1702 OVERRIDE FREQ .
2 = PID – The reference is taken from the PID output, see group Group 40: Process
PID set 1 .
Note: The following conditions must be met when using PID in the override mode:
• PID1 setpoint (parameter 4010 SET POINT SEL ) can be either A1, A2 OR
INTERNAL PID1 parameter set 1 must be active (parameter 4027 PID 1 PARAM
SET = set 1).
• Override direction (parameter 1706 OVERRIDE DIR ) can be either 0 = forward
or 7 = reverse.
Group 18: Freq in & tran out
Code Description Range Resolution Default S
1801 FREQ INPUT MIN 0 … 16000 Hz 1 =1 Hz 0 Hz
Defines the minimum input value when DI5 is used as a frequency input. See section
Frequency input on page 111 .
1802
FREQ INPUT MAX
0 … 16000 Hz 1 =1 Hz 1000 Hz
Defines the maximum input value when DI5 is used as a frequency input. See section
Frequency input on page 111 .
1803 FILTER FREQ IN 0.0 … 10.0 s 1 = 0.1 s 0.1 s
Defines the filter time constant for frequency input, ie the time within 63% of a step
change is reached. See section
Frequency input on page 111 .
1804 TO MODE DIGITAL
Selects the operation mode for the transistor output TO. See section Transistor output
on page 111 .
0 = DIGITAL – Transistor output is used as a digital output DO.
1 = FREQUENCY – Transistor output is used as a frequency output FO.
1805 DO SIGNAL FAULT (-1)
Selects a drive status indicated through digital output DO. See parameter 1401
RELAY OUTPUT 1 .
1806
DO ON DELAY
0.0 … 3600.0 s 1 = 0.1 s 0.0 s
Defines the operation delay for digital output DO.
1807 DO OFF DELAY 0.0 … 3600.0 s 1 = 0.1 s 0.0 s
Defines the release delay for digital output DO.
1808
FO CONTENT SEL
0…178 104
Selects a drive signal to be connected to frequency output FO. Parameter index in
