Setting 14: Fault ResetWhen the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts tostop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Runcommand, clear the fault either by pressing the RESET key on the HOA keypad or closing a digital input configured as a FaultReset (H1-oo = 14).Note: Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.Setting 19: PI DisableClose a digital input to indefinitely disable the PI function. When the input is released, the drive resumes PI operation. Referto PI Block Diagram on page 130.Setting 24: External FaultThe External fault command stops the drive when problems occur with external devices.To use the External fault command, set one of the multi-function digital inputs to 24. The HOA keypad will display EFowhere o is the number of the terminal to which the external fault signal is assigned.For example, if an external fault signal is input to terminal DI-3, “EF3” will be displayed.The conditions of setting 24 are:• Terminal status is normally open• Detection condition is always detected• Stopping method is coast to stop.Setting 60: Motor Pre-Heat 1A DC current can be circulated through the motor windings to create heat and prevent moisture from condensing on the wire.Motor Pre-Heating can only be initiated by closing a digital input programmed as a Motor Pre-Heat input (H1-oo = 60). Thelevel of the DC current used by the Motor Pre-Heat function is determined by b2-09<1>.<1> Details on this function can be found in the standard Z1000 Programming Manual (SIEPC71061645) atwww.yaskawa.com.A Run input will be given priority over a Motor Pre-Heat input and when the Run command is removed, the motor pre-heatingwill resume if the Motor Pre-Heat input is still closed.Motor Pre-Heat 1commandFWD Run commandOutput frequencyMotor Pre-Heat 1Motor Pre-Heat 1brakingMotor Pre-Heat 1Start Frequency(b2-01)OFFOFF OFFOFFONONFigure 5.21 Motor Pre-Heat 1 Input Timing Diagramu H2: Multi-Function Digital OutputsNote: H2-oo parameters are available in bypass controller software versions VST800298 and later.n H2-01 to H2-03: Terminal M1-M2, M3-M4, and M5-M6 Function SelectionThe bypass has three multi-function output terminals.
