Dear all,

I have problem with VFAS1 Toshiba. I use one inverter unit VFAS1-160kw to drive for one motor 104kw. But I cannot run in sensorless vector mode. When I try to run in this mode, inverter trips as starting (overcurrent trip). What can I do so inverter can run in this mode?

Motor data:
Wordl Energy
Toshiba 3 phase induction motor
104kW - 360VAC - 56Hz - 225A - 6P - 1100rpm
Type: TIKL
Form: ECKM8
Frame: 280m

Thanks and best regards,
Chungtq
