ru.37 motorpoti actual value 0225h RO - - -100 100 0.01 % -
The motorpoti-function in the KEB COMBIVERT imitates a mechanical, motor operated potentiometer. The
control occurs via 2 programmable inputs („poti up“ and „poti down“). The display is limited by oP.53/ 54. The
adjustment of the motorpoti is done with the parameters oP.50...oP.59 (also see chapt. 7.15.3 „Motorpoti“). By
way of the bus the motorpoti can be set to any chosen value between -100...100%. In addition to the inputs
the motorpoti can be operated with the keys „UP“ and „DOWN“. Then the rate of change is not constant.
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.38 power module tempe-
rature
0226h RO - - 0 150 1 °C -
ru.38 shows the current power stage temperature of the inverter.
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.39 Overload integrator
(E.OL)
0227h RO - - 0 100 1 % -
In order to preclude „E.OL“ - errors by too high load (load reduction in due time), the internal count of the OL-
counter can be made visible with this display. At 100 % the inverter switches off with error „E.OL“. The error
can be reset only after a cooling time (blinking display „E.nOL“).
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.40 power on counter 0228h RO - - 0 65535 1 h -
The operating hours meter shows the time the inverter was switched on. The indicated value comprises all
operating phases. On reaching the maximum value (approx. 7.5 years) the display remains on the maximum
value.
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.41 modulation on counter 0229h RO - - 0 65535 1 h -
The modulation hours meter shows the time the inverter was active (power modules controlled). On reaching
the maximum value (approx. 7.5 years) the display remains on the maximum value.
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.42 modulation grade 022Ah RO - - 0 110 1 % -
The modulation factor shows the output voltage in percent. 100 % correspond to the input voltage (no-load).
At a value of > 100 % the inverter works with overmodulation.
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.43 timer 1 display 022Bh RO - - 0 655,35 0.01 - -
The count of the free-programmable timer 1 is indicated. The display is done either in seconds, in hours or in
slopes/100 (see LE.21). The counter can be adjusted to any chosen value by keyboard or bus. The program-
ming of the counter is done with the parameters LE.17...LE.21 (see also chapter 7.15 „Timer“).
Parameter Addr. R PG E Min. value Max. value Res. [?] Default
ru.44 timer 2 display 022Ch RO - - 0 655,35 0.01 - -
The count of the free-programmable timer 2 is indicated. The display is done either in seconds, in hours or in
slopes/100 (see LE.26). The counter can be adjusted to any chosen value by keyboard or bus. The program-
ming of the counter is done with the parameters LE.22...LE.26 (see also chapter 7.15 „Timer“).
