Danfoss VLT CDS 302 User Manual

6.7 Par. Group 6 - Analog In/Out
Parameter group for conguration of the analog input and
output.
6.7.1 6-0* Analog In/Out Mode
Parameter group for setting up the analog In/Out congu-
ration.
The frequency converter is equipped with 2 analog inputs:
Terminal 53 and 54. The analog inputs on the frequency
converter can freely be allocated to either voltage (-10 V to
+10 V) or current input (0/4 to 20 mA).
6-00 Live Zero Timeout Time
Range: Function:
10 s* [1 -
99 s]
Enter the Live Zero Time-out time period. Live
Zero Time-out Time is active for analog inputs, i.e.
terminal 53 or terminal 54, used as reference or
feedback sources. If the reference signal value
associated with the selected current input falls
below 50% of the value set in
parameter 6-10 Terminal 53 Low Voltage,
parameter 6-12 Terminal 53 Low Current,
parameter 6-20 Terminal 54 Low Voltage or
parameter 6-22 Terminal 54 Low Current for a time
period longer than the time set in
parameter 6-00 Live Zero Timeout Time, the
function selected in parameter 6-01 Live Zero
Timeout Function will be activated.
6-01 Live Zero Timeout Function
Option: Function:
Select the time-out function. The function set
in parameter 6-01 Live Zero Timeout Function
will be activated if the input signal on terminal
53 or 54 is below 50% of the value in
parameter 6-10 Terminal 53 Low Voltage,
parameter 6-12 Terminal 53 Low Current,
parameter 6-20 Terminal 54 Low Voltage or
parameter 6-22 Terminal 54 Low Current for a
time period dened in parameter 6-00 Live Zero
Timeout Time. If several time-outs occur
simultaneously, the frequency converter
prioritizes the time-out functions as follows:
1. Parameter 6-01 Live Zero Timeout
Function
2. Parameter 8-04 Control Word Timeout
Function
[1] Freeze
Output
Frozen at the present value
[0] * O
6-01 Live Zero Timeout Function
Option: Function:
[1] Freeze
output
Frozen at the present value
[2] Stop Overruled to stop
[3] Jogging Overruled to jog speed
[4] Max. speed Overruled to max. speed
[5] Stop and
trip
Overruled to stop with subsequent trip
6.7.2 6-1* Analog Input 1
Parameters for conguring the scaling and limits for analog
input 1 (terminal 53).
NOTICE!
Analog input 53 is preset for usage with “Open Loop”
control on 0-10 V. Terminal 54 is preset for “Process
Loop” control using a pressure sensor AKS with a
pressure range of -14 : 174 psi.
6-10 Terminal 53 Low Voltage
Range: Function:
0.00V* [-10.0 - par.
6-11]
This analog input scaling value should
correspond to the minimum reference
value, set in parameter 3-02 Minimum
Reference.
6-11 Terminal 53 High Voltage
Range: Function:
10.00 V* [6-10 to 10 V] This analog input scaling value should
correspond to the maximum reference
value, set in par. 3-03.
6-12 Terminal 53 Low Current
Range: Function:
4.0mA* [0.0 to par.
6-13 mA]
This reference signal should correspond
to the minimum reference value, set in
parameter 3-02 Minimum Reference.
6-13 Terminal 53 High Current
Range: Function:
20.0mA* [6-12 to 20
mA]
This reference signal should correspond
to the maximum reference value, set in
parameter 3-02 Minimum Reference.
6-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
Size
related*
[Enter the analog input scaling value
that corresponds to the low voltage/low
current set in parameter 6-10 Terminal 53
