MG.20.O2.02 - VLT
Function:
spond to the low reference/feedback value, set in par. 6-24. The
value must be set at >2 mA in order to activate the Live Zero
Time-out Function in par. 6-01.
Function:
Enter the high current value corresponding 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 par. 6-20/6-22.
Function:
Enter the analog input scaling value that corresponds to the high
voltage/high current value set in par. 6-21/6-23.
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 increa-
ses the time delay through the filter.
This parameter cannot be adjusted while the motor is running.
Function:
This parameter makes it possible to disable the Live Zero mon-
itoring. 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 frequency
converter related control functions, but feeding an external con-
trol system with data)
