1397 Enhanced Field Supply Card Setup P.272 E-Fld Volts Adj (continued) Parameter P.272 [E-Fld Volts Adj] is used to match the drive’s rated field voltage to different DC motor field voltages. A field voltage below the motor’s rated value can operate the motor above rated base speed with reduced torque. A voltage above the motor’s rated base speed however, could also result in armature overvoltage and overheating of the motor’s field windings.
