6-16 Terminal 53 Filter Time Constant
Range: Function:
0.01 s* [0.01 -
10.0 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
dampening but also increases the time delay
through the filter.
This parameter cannot be adjusted while the
motor is running.
6-19 Terminal 53 mode
Option: Function:
Select if terminal 54 is used for current- or
voltage input.
[0] Current mode
[1] Voltage mode
3.7.3 6-2* Analog Input 54
Parameters for configuring the scaling and limits for analog
input 54 (terminal 54).
6-20 Terminal 54 Low Voltage
Range: Function:
0.07 V* [0.0 - 10.0
V]
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.
6-21 Terminal 54 High Voltage
Range: Function:
10.0 V* [0.0 - 10.0 V] Enter the voltage (V) that corresponds to
the high reference value (set in
6-25 Terminal 54 High Ref./Feedb. Value).
6-22 Terminal 54 Low Current
Range: Function:
4.0 mA* [0.0 -
20.0 mA]
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.
6-23 Terminal 54 High Current
Range: Function:
20.0 mA*
20.00 mA*
[0.0 - 20.0 mA]
[par. 6-22 - 20.00
mA]
Enter the high current value
corresponding to the high
reference/feedback value set in
6-25 Terminal 54 High Ref./Feedb.
Value.
6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
0.0 * [-4999.0 -
4999.0 ]
Enter the reference or feedback value
that corresponds to the voltage or
current set in 6-21 Terminal 54 High
Voltage/6-22 Terminal 54 Low Current.
6-25 Terminal 54 High Ref./Feedb. Value
Range: Function:
50.0 * [-4999.0 -
4999.0 ]
Enter the reference or feedback value
that corresponds to the voltage or
current set in 6-21 Terminal 54 High
Voltage/6-23 Terminal 54 High Current.
6-26 Terminal 54 Filter Time Constant
Range: Function:
0.01 s* [0.01 -
10.0 s]
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.
This parameter cannot be adjusted while the
motor is running.
6-29 Terminal 54 mode
Option: Function:
Select if terminal 54 is used for current- or
voltage input.
[0] Current mode
[1] Voltage mode
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.
6-70 Terminal 45 Mode
Option: Function:
Set terminal 45 to act as analog output or as
digital output.
[0] * 0-20 mA
[1] 4-20 mA
[2] Digital Output
6-71 Terminal 45 Analog Output
Option: Function:
Select the function of Terminal 45 as an
analog current output. See also
6-70 Terminal 45 Mode.
[0] * No operation
[100] Output frequency 0 - 100Hz
