10.1.19 Detection of motor not connected to inverter output terminal<br />

Chapter 10 Protective Functions<br />

Group Code No. Function Display Setting Display Setting Range Unit<br />

PRT<br />

31 No Motor Trip 0 None - -<br />

32 No Motor Level 7 10 1~100 %<br />

33 No Motor Time 0.5 0.1~10.0 sec<br />

If an operating command is given with the motor not connected to the output terminal of the inverter, No Motor Trip is<br />

released to protect the system. No Motor Trip occurs when the inverter’s output current against the rated<br />

current(BAS13) continues to be below PRT32(No Motor Level) for PRT33(No Motor Time).<br />

Caution<br />

If BAS-07 V/F Pattern is set at 1 Square, set the PRT-32 No Motor Level lower than the value at the time<br />

of delivery from the plant. Otherwise, No Motor Trip might occur because of low output current in its<br />

initial starting.<br />
