C04.6* Speed Bypass
In some applications mechanical resonance may occur. Avoid resonance
points by creating a bypass. The frequency converter ramps through the
bypass area thereby passing mechanical resonance points quickly.
●
Function:
Array [2]
Enter either the lower or upper limit of the speeds to be avoided. It
does not matter whether Bypass From or Bypass Too is the upper or
lower limit, however the Speed Bypass function is disabled if the two
parameters are set to the same value.
C04.61 Bypass Speed From [Hz]
Default setting 0.0Hz
Range
[0.0 - 400.0 Hz]
●
Function:
Array [2]
Enter either the upper or lower limit of the speed area to be avoided.
Make sure to enter the opposite limit of that in par. C04.61 Speed
Bypass From [Hz].
C04.63 Bypass Speed To [Hz]
Default setting 0.0Hz
Range
[0.0 - 400.0 Hz]
Parameter group 5: Digital In/Out
The following describes all digital input command functions and signals.
C05.1* Digital Inputs
Parameters for configuring the functions for the input terminals.
The digital inputs are used for selecting various functions in the
frequency converter. All digital inputs can be set to the following:
●
Function:
A missing motor phase causes the motor torque to drop.
This monitor may be disabled for special purposes (eg. small motors
running pure V/F mode), but as there is a risk of overheating the motor,
Danfoss strongly recommends that the function is On.
A missing motor phases causes the frequency converter to trip and
report an alarm.
●
ATTENTION!
This parameter cannot be changed while motor runs.
