Hi, We moved from a Micromaster MM25/2 to a Sinamics G120 inverter, to drive a simple asynchronous fan. The motor rating plate read out is: H 50 V 125/220 A 1.9/1.1 RPM 2650 Kw 0.22 We are using the STARTER Comissioning Tool to set up the parameters: Control Unit CU240S PN Power module PM240 But we can not drive the fan. A message 503 undervoltage limit alarm appears and we do not know how to go forward. The MM25/2 was configured to drive a 220V 50Hz 1.1A induction motor, thus we expect the G120 can drive it too, using the U/f linear mode. Configuration screenshoots are attached. Any help would be very appreciated. Manuel Attachmentconfig.zip (406 Downloads) |

The PM240 is not a single phase drive hence your undervoltage |
