Operating Display

The 4 parameters below serve to control the frequency inverter during operation.
Display of the actual output frequency with a resolution of 0.0125 Hz. The
rotation of the inverter is indicated by the sign.
Examples:
The status display shows the actual working conditions of the inverter. Possible
displays and their meanings are:
" no Operation " control release (terminal X1.19) not bridged,
modulation switched off, output voltage = 0 V, drive is not
controlled.
" Low Speed " no rotation preset ( terminal X1.10 or X1.11),
modulation switched off, output voltage = 0 V, drive is not
controlled.
" Forward Acceleration " drive accelerates with a forward
direction of rotation.
" Forward Deceleration " drive decelerates with a forward
direction of rotation.
" Reverse Acceleration " drives accelerates with a reverse
direction of rotation.
" Reverse Deceleration " drive decelerates with a reverse
direction of rotation.
" Forward Constant " drive runs with a constant speed and a
forward direction of rotation.
" Reverse Constant " drive runs with constant speed and a
reverse direction of rotation.
Other status messages are described at the parameters, which they cause.
Display of the actual inverter rate of utilization in percent. 100% rate of utilization
is equal to the inverter rated current. Only positive values are displayed,
meaning there is no differentiation between motor and regenerative operation.
This display makes it possible to recognize short-term fluctuations of the rate
of utilization by storing the highest value that occurred. The display occurs in
percent (100% = inverter rated current).
With the UP or DOWN key the peak value can be reset when the unit
is on. As a result it is possible to measure the highest rate of utilization
in certain operating phases. Switching off the unit deletes the peak
value.
Output frequency 18.3 Hz, rotation forward
Output frequency 18.3 Hz, rotation reverse
