Setting 7: Torque Detection LevelUsing this setting, the overtorque/undertorque detection level for torque detection 1 (L6-01) can be set by an analog input.The analog input replaces the level set to L6-02. An analog input of 100% (10 V or 20 mA) sets a torque detection level equalto 100% drive rated current/motor rated torque. Adjust the analog input gain if higher detection level settings are required.Refer to L6: Torque Detection on page 114 for details on torque detection.Setting 8: Stall Prevention LevelAllows an analog input signal to adjust the Stall Prevention level. Figure 1.54 shows the setting characteristics. The drive willuse the lower value of the Stall Prevention level set to L3-06 or the level coming from the selected analog input terminal.Stall Prevention Level during Run30%100%Analog Input Level30% 100%0Figure 1.54 Stall Prevention During Run Using an Analog Input TerminalSetting 9: Output Frequency Lower Limit LevelThe user can adjust the lower limit of the output frequency using an analog input signal.Setting B: PI FeedbackSupplies the PI feedback value. This setting requires PI operation to be enabled in b5-01. Refer to PI Feedback InputMethods on page 38.Setting C: PI SetpointSupplies the PI setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PI setpoint. PIoperation to be enabled in b5-01 to use this setting. Refer to PI Setpoint Input Methods on page 37.Setting D: Frequency BiasThe input value of an analog input set to this function will be added to the frequency reference. This function can be used withany frequency reference source.Setting E: Motor TemperatureIn addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient) thermistorfor motor insulation protection.Setting F: Through ModeWhen set to F, an input does not affect any drive function, but the input level can still be read out by a PLC via APOGEEFLN, BACnet, MEMOBUS/Modbus, or Metasys N2 communications.Setting 16: Differential PI FeedbackIf an analog value is set for this function, the PI controller is set for differential feedback. The difference of the PI feedbackinput value and the differential feedback input value builds the feedback value used to calculate the PI input. Refer to PIFeedback Input Methods on page 38.u H4: Multi-Function Analog OutputsThese parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of driveperformance.n H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor SelectionSets the desired drive monitor parameter Uo-oo to output as an analog value via terminal FM and AM. Refer to U: MonitorParameters on page 158 for a list of all monitors. The “Analog Output Level” column indicates whether a monitor can beused for analog output.Example: Enter “103” for U1-03.1.7 H: Terminal Functions96 YASKAWA SIEP YAIZ1U 03B YASKAWA AC Drive – Z1000 Programming Manual
