6-20 Terminal 54 Low Voltage
Value:
0.00 – par. 6-21
0.07V
Function:
Enter the low voltage value. This analog input
scaling value should correspond to the low
reference/feedback value, set in par. 6-24.
6-21 Terminal 54 High Voltage
Value:
Par. 6-20 to 10.0 V
10.0V
Function:
Enter the high voltage value. This analog input
scaling value should correspond to the high
reference/feedback value set in par. 6-25.
6-24
Terminal 54 Low Ref./Feedb.
Value
Value:
-1000000.000 to par. 6-25
0.000 Unit
Function:
Enter the analog input scaling value that cor-
responds to the low voltage/low current value
set in par. 6-20/6-22.
6-25
Terminal 54 high ref./feedb.
value
Value:
Par. 6-24 to 1000000.000
100.000 Unit
Function:
Enter the analog input scaling value that cor-
responds to the high voltage/high current val-
ue set in par. 6-21/6-23.
6-26
Terminal 54 Filter Time Con-
stant
Value:
0.001 - 10.000 s
0.001s
Function:
Enter the time constant. This is a first-order
digital low pass filter time constant for sup-
pressing electrical noise in terminal 54. A high
time constant value improves dampening but
also increases the time delay through the fil-
ter.
This parameter cannot be adjusted while the
motor is running.
6-27 Terminal 54 Live Zero
Value:
Disabled [0]
Enabled [1]
Function:
This parameter makes it possible to disable
the Live Zero monitoring. E.g. to be used if the
analog outputs are used as part of a decentral
I/O system (e.g. when not part of any fre-
quency converter related control functions,
but feeding a Building Management System
with data)
6-50 Terminal 42 Output
Value:
No operation [0]
Output frequency [100]
Reference [101]
Feedback [102]
Motor current [103]
Torque rel to lim [104]
Torque rel to rated [105]
Power [106]
Speed [107]
Torque [108]
Ext. closed loop 1 [113]
Ext. closed loop 2 [114]
Ext. closed loop 3 [115]
Output freq. 4-20mA [130]
Reference 4-20mA [131]
Feedback 4-20mA [132]
Motor cur. 4-20mA [133]
Torque % lim. 4-20mA [134]
Torque % nom 4-20mA [135]
Power 4-20mA [136]
Speed 4-20mA [137]
Torque 4-20mA [138]
Bus ctrl. 0-20 mA [139]
Bus ctrl. 4-20 mA [140]
Bus ctrl. 0-20 mA, timeout [141]
Bus ctrl. 4-20 mA, timeout [142]
