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 rege-
nerative 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 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
