Range:
0.07 V* [ 0.00 - par. 6-21 V]
6-21 Terminal 54 High Voltage
Range:
6
10.00 V* [ par. 6-20 - 10.00 V]
6-24 Terminal 54 Low Ref./Feedb. Value
Range:
0.000 * [-999999.999 - 999999.999 ]
6-25 Terminal 54 High Ref./Feedb. Value
Range:
100.000 * [-999999.999 - 999999.999 ]
6-26 Terminal 54 Filter Time Constant
Range:
0.001 s* [0.001 - 10.000 s]
This parameter cannot be adjusted while the motor
is running.
6-27 Terminal 54 Live Zero
Option:
[0] Disabled
[1] * Enabled
6-50 Terminal 42 Output
Option:
[0] * No operation
[100] Output freq. 0-100

Function:
This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the ana-
log outputs are used as part of a de-central I/O system (e.g. when not as part of any frequency
converter related control functions, but feeding a Building Management system with data).
Function:
Enter the low voltage value. This analog input scaling value should correspond to the low refer-
ence/feedback value, set in par. 6-24
Function:
Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 6-25
Function:
Enter the analog input scaling value that corresponds to the low voltage/low current value set in
Terminal 54 Low Voltage and par. 6-22 Terminal 54 Low Current .
par. 6-20
Function:
Enter the analog input scaling value that corresponds to the high voltage/high current value set in
par. 6-21 Terminal 54 High Voltage and par. 6-23 Terminal 54 High Current .
Function:
Enter the time constant. This is a first-order digital low pass filter time constant for suppressing
electrical noise in terminal 54. A high time constant value improves dampening but also increases
the time delay through the filter.
Function:
This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the ana-
log outputs are used as part of a de-central I/O system (e.g. when not as part of any frequency
converter related control functions, but feeding a Building Management System with data).
Function:
Select the function of Terminal 42 as an analog current output. A motor current of 20 mA corre-
sponds to I .
