Appendix D—Modbus Register Map258 Power Xpert C445 Global Motor Management Relay MN042003EN—October 2016 www.eaton.com726 Q3 Latch Behavior PowerDownUINT8 RW NVDefault: 0EnumConfig CRCAdmin LockUSB LockBackup MemSelect the behavior of the Latching Relay (Output 3) when power isremoved from the C445, provided the Base Control Module was orderedwith the latching relay option. Default: Turn Off, emulating a non-latchingrelay.727 Phase Type UINT8 RW NVDefault: 0EnumConfig CRCRun LockAdmin LockUSB LockBackup MemThree-phase configuration is the default and is used for 3-phase motors.The C445 also supports single phase motors by changing this setting toSingle Phase.728 2-Wire/3-Wire UINT8 RW NVDefault: 0EnumConfig CRCRun LockAdmin LockUSB LockBackup MemSelects 2 or 3 wire control. When 2-Wire Control is used, the fieldwireinputs are designed to a run signal. If a signal is present at the run input, itwill command to run while if no signal is present, it will stop or not run.When 3-Wire control is Used, a second fieldwire input is designated toaccept a Run input and a Permissive input. When in fieldwire control, themotor will not be allowed to run if the Permissive signal is not present.Additionally, if the permissive is removed while running, the motor willstop. The Run input in 3-Wire Control can accept a maintained or pulsedrun command.729 Digital Input Debounce UINT16 RW NVArray size: 4Default: 20Range: 5 to 5000Units: msBackup MemDigital Input Debounce. One 16-bit value for each of the 4 inputs on theBase Control Module. The same value is used for both rising and fallingedges.Array of 4 registers737 Control User InterfaceButton LED 1 PurposeUINT16 RW NVDefault: 1EnumConfig CRCAdmin LockUSB LockBackup MemConfiguration parameter for the User Interface button LED 1.
