3.8.3 6-1* Analog Input 1
Parameters for configuring the scaling and limits for analog input 1 (terminal 53).
6-10 Terminal 53 Low Voltage
Range: Function:
0.07 V* [0.00 - par. 6-11 V] Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par.6-14
Terminal 53 Low Ref./Feedb. Value .
6-11 Terminal 53 High Voltage
Range: Function:
10.00 V* [par. 6-10 - 10.00 V] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par.6-15
Terminal 53 High Ref./Feedb. Value .
6-12 Terminal 53 Low Current
Range: Function:
4.00 mA* [0.00 - par. 6-13 mA] Enter the low current value. This reference signal should correspond to the low reference/feedback
value, set in par.6-14
Terminal 53 Low Ref./Feedb. Value . The value must be set at >2 mA in order
to activate the Live Zero Timeout Function in par.6-01
Live Zero Timeout Function .
6-13 Terminal 53 High Current
Range: Function:
20.00 mA* [par. 6-12 - 20.00 mA] Enter the high current value corresponding to the high reference/feedback set in par.6-15 Terminal
53 High Ref./Feedb. Value
.
6-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the low voltage/low current set in par.
6-10
Terminal 53 Low Voltage and par.6-12 Terminal 53 Low Current .
6-15 Terminal 53 High Ref./Feedb. Value
Range: Function:
50.000 N/
A*
[-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the high voltage/high current value set in
par.6-11
Terminal 53 High Voltage and par.6-13 Terminal 53 High Current .
6-16 Terminal 53 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10.000 s] Enter the time constant. This is a first-order digital low pass filter time constant for suppressing
electrical noise in terminal 53. A high time constant value improves damping, but also increases the
time delay through the filter.
This parameter cannot be adjusted while the motor is running.
6-17 Terminal 53 Live Zero
Option: Function:
This parameter makes it possible to disable the Live Zero monitoring. For example, this is to be used
if the analog outputs are used as part of a de-central I/O system (e.g., when not used as part of
any adjustable frequency drive related control functions, but for feeding a building management
system with data).
