Peak Inverter Utilization
8. Parameter Description
Display of the actual apparent current. Resolution 0.1A
Shows the actual inverter status.
See status/error messages pages GB 44 - GB 45
ru.8 makes it possible to immediately detect peak utilization within
an operating cycle. In addition the highest value that occurs in LF.87
is stored in ru.8. The peak memory can be deleted by pressing the
UP or DOWN key, or with Bus by writing any value onto the address
of ru. 8. The memory is deleted when the inverter is switched off.
The actual operating condition of the inverter can be read in these
parameters. The parameters in this group are read-only. Exception:
parameters ru.8, ru.12 and ru.25 can be reset with the serial
interface by entering any value. You can also use the keyboard and
do the reset with the UP/DOWN keys.
In ru. 4 the set speed value, at the output of the ramp generator, is
displayed. If the modulation is switched off or abnormal operating
state is active, then the actual setpoint 0 rpm is shown.
During controlled operation this parameter shows the output
frequency in rpm.
Displays actual motor torque (calculated from the active current).
Max. tolerance approx. +/-20% in the basic speed range (in the field
weakening range larger tolerances are possible).
During open loop operation 0 is always shown.
