UC can be set to 0 if UC protection is not desired. The 777- P1 examines average current to determine if an undercurrent trip condition exists. CUB - SymCom recommends contacting the motor manufacturer for a specific setting. Current unbalance is calculated the same way voltage unbalance is calculated (see formula above). - Page 6 Table 2 shows the next restart delay vs. run time. In general, a longer run time produces a shorter restart delay. This feature allows the 777-P1 to optimize running and rest times automatically. © 2009 SymCom, Inc. All Rights Reserved...
