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 for free selection of either voltage (-10V
- +10V) or current input (0/4 - 20 mA).
NOTE
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 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:
Activates the function if the input signal on terminal
53 or 54 drops below 2 mA, provided that par.
6-12 or 6.22 is set higher than 2 mA, and that
the time for timeout in par. 6-00 is exceeded.
If more timeouts occur at the same time, the
adjustable frequency drive makes the following
priority of the time-out function:
Live Zero Time-out Function par. 6-01
1.
Encoder Loss Function par. 5-74
2.
Control-word Time-out Function par. 8-04.

6-10 Terminal 53 Low Voltage
Range:
0.0 - 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.
