Zero Speed (Setting: 1)
OFF The output frequency is higher than the zero speed level (b2-01).
ON The output frequency is lower than the zero speed level (b2-01).
Output frequency
Zero-speed output
Inverter Operation Ready (Setting: 6)
If a multifunction output is programmed for this function the output will be switched ON when the initialisa-
tion of the inverter at startup has finished without any faults.
During DC Bus Undervoltage (Setting: 7)
If a multifunction output is programmed for this function the output is switched ON as long as a DC bus
undervoltage is detected.
During Baseblock (Setting: 8)
If a multifunction output is programmed for this function the output is switched ON as long as the inverter out-
put is base blocked.
Frequency Reference Source Selection (Setting: 9)
If a multifunction output is programmed for this function the output is ON when the digital operator is selected
as frequency reference source. If any other frequency reference is selected the output is switched OFF.
Run Command Selection Status (Setting: A)
If a multifunction output is programmed for this function the output is switched ON when the digital operator
is selected as RUN command source. If any other RUN command source is selected output is switched OFF.
Fault Output (Setting: E)
If a multifunction output is programmed for this function the output is switched ON when any fault different
from CPF00 and CPF01 occurs. The output is also not switched at minor faults. (Refer to
fault list.)
Minor Fault Output (Setting: 10)
If a multifunction output is programmed for this function the output is switched ON when a minor fault occurs
