Hello, there is no DC-link voltage present in drive. It could be caused badly line voltage setting in p210, failure in power supply, f.e. one phase missing or precharging time is too short in p857. All these causes and remedy are described in list manual for CU240E-2. Check line power supply voltage and DC-link voltage during drive start (trace r70 or using multimeter on DC-link terminals DCP and DCN). With regards Martin |
