Parameters: Analog In/Out

"
6-0* Analog I/O Mode
"
FC 300 is equipped with 2 analog inputs: Terminal
53 and 54. The analog inputs on FC 302 are
designed to free selection for either voltage (–10V
- +10V) or current input (0/4 – 20 mA).
NB!:
Thermistors are connected either to an
analog or a digital input.
6-00 Live Zero Timeout Time
Range:
1 - 99 s
Function:
Is active when A53 (SW201) and /or A54 (SW202)
is/are in the position ON (the analog inputs are
selected to current inputs). If the reference signal
value connected to the selected current input falls
below 50% of the value set in par. 6-12 or par. 6-22
for a time period longer than the time set in par.
6-00, the function selected in par. 6-01 is activated.
6-01 Live Zero Timeout Function
Option:
*
Off
Freeze Output
Stop
Jogging
Max. speed
Stop and trip
Function:
The function set in par. 6-01 will be activated
if the input signal on terminal 53 or 54 is below
50% of the value in par. 6-10, par. 6-12, par.
6-20 or par. 6-22 for a time period defined in
par. 6-00. If more time-outs occur at the same
time, the frequency converter makes the following
priority of the time-out function:
Live Zero Time-out Function par. 6-01
1.
2. Encoder Loss Function par. 5-74
Control-word Time-out Function par. 8-04.
3.
The output frequency of the frequency
converter can be:
frozen at the present value
•
overruled to jog speed
•
overruled to max. speed
•
overruled to stop with subsequent trip
•
• Par. 6-01 cannot be adjusted while the
motor is running.

6-1* Analog Input 1
"
Parameters for configuring the scaling and limits
for analog input 1 (terminal 53).
10s
6-10 Terminal 53 Low Voltage
Range:
-10.0 - par. 6-11
Function:
Sets the analog input scaling value to correspond to
the minimum reference value (set in par. 3-02).
6-11 Terminal 53 High Voltage
Range:
Par. 6-10 to 10.0 V
Function:
Sets the analog input scaling value to correspond to
the maximum reference value (set in par. 3-03).
6-12 Terminal 53 Low Current
Range:
0.0 to par. 6-13 mA
Function:
Determines the value of the reference signal to
correspond to the minimum reference value (set in
par. 3-02). If the Time-out function of par. 6-01
is activated, the value must be set at >2 mA.
6-13 Terminal 53 High Current
Range:
Par. 6-12 to - 20.0 mA
Function:
Sets the value of the reference signal to correspond
to the maximum reference value (set in par. 3-03).
