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 >1 V in order to activate 6-01 Live Zero
Timeout Function.
Function:
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

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: 0/4-20 mA. Resolution on analog output is
12 bit. Analog output terminals can also be set up for
digital output.
