VLT HVAC Basic Drive Programming Guide
Function:
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
dampening but also increases the time delay
through the filter.
This parameter cannot be adjusted while the
motor is running.
Function:
Select if terminal 54 is used for current- or
voltage input.
Function:
Enter the voltage (V) that corresponds to the
low reference value (set in 6-24 Terminal 54
Low Ref./Feedb. Value). The value must be set
at >1V in order to activate 6-01 Live Zero
Timeout Function.
Function:
the high reference value (set in
6-25 Terminal 54 High Ref./Feedb. Value).
Function:
Enter the low current value. This reference
signal should correspond to the low
reference/feedback value, set in 6-24 Terminal
54 Low Ref./Feedb. Value. The value must be
set at >2 mA in order to activate the Live Zero
Timeout Function in 6-01 Live Zero Timeout
Function.
Function:
Enter the high current value
corresponding to the high
reference/feedback value set in
6-25 Terminal 54 High Ref./Feedb.

3.7.4 6-7* Analog/Digital Output 45

Parameters for configuring the scaling and limits for analog/
digital output Terminal 45. Analog outputs are current
outputs: 0/4 - 20mA. Resolution on analog output is 12 bit.
Analog output terminals can also be setup as digital output.

Function:
Enter the time constant. This is a first-order

Function:
Set terminal 45 to act as analog output or as
digital output.
Function:
