409 Terminal 01 Relay Output (RELAY 01)
Value:
★
Unit ready (UNIT READY)
[0]
Unit ready - remote control (UNT RDY RCTL)
[1]
Enabled no warning (ENABLED noWR)
[2]
Running (RUNNING)
[3]
Running, no warning (RUNNING noWR)
[4]
Running in range, no warning (RUNinRANGE)
[5]
Running on reference, no warn (RUN@REF noWR) [6]
Alarm (ALARM)
[7]
Alarm or warning (ALARM or WARN)
[8]
Current limit (CURRENT LIMIT)
[9]
Out of frequency range (OUT FREQ RGE)
[10]
Out of current range (OUT CURR RGE)
[11]
Reversing (REVERSING)
[12]
Description:
You can use the relay output 01 to indicate selected status
and warnings. The relay is activated when the conditions
for the selected data values are fulfilled.
When relay output 01 is not active, there is no connection
between terminal 01 and 02. The relay output is potential-
free and the maximum load is 2 A at 24 VDC or 250 VAC.
411 Analog Input Current (ANALOG REFTYPE)
Value:
★
Linear between minimum and maximum (LINEAR)
[0]
Proportional with lower limit (PROP W/LIMIT)
[1]
Function:
Is used to determine which frequency converter is to follow
an analog reference signal.
Description:
When you select [1] the reference signal will not affect the
output frequency until it reaches a value equivalent to the
set minimum frequency (parameter 201).
412 Terminal 53 Analog Input Voltage
(INPUT #53)
Value:
No Function (NO FUNCTION)
[0]
★
0 to 10 V (0 to 10 V DC)
[1]
10 to 0 V (10 to 0 V DC)
[2]
Description:
Record the polarity of analog control signals to inputs 53
and 60. You can choose between voltage, current and
polarity.
If you use both inputs for reference signals the total
reference signal will be a summation.
413 Terminal 60 Analog Input Current
(INPUT #60)
Value:
No Function (NO FUNCTION)
[0]
★
0 to 20 mA (0 to 20 mA)
[1]
4 to 20 mA (4 to 20 mA)
[2]
20 to 0 mA (20 to 0 mA)
[3]
20 to 4 mA (20 to 4 mA)
[4]
Description:
If you are using a PI controller one of the inputs or the pulse
input must be used for the feedback signal.
If you are using current control, one of the inputs must be
used to set a current limit.
Naturally these choices block the same type of reference
signal.
