5.7 H: Terminal FunctionsYASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual 239Parameter Details5Setting 9: Output frequency lower limit levelThe user can adjust the lower limit of the output frequency using an analog input signal.Setting B: PID feedbackAn input set for this function supplies the PID feedback value. This setting requires PID operation to be enabled in b5-01.Refer to PID Feedback Input Methods on page 153.Setting C: PID setpointAn input set for this function supplies the PID setpoint value, and the frequency reference selected in parameter b1-01 isno longer the PID setpoint. PID operation to be enabled in b5-01 to use this setting. Refer to PID Setpoint InputMethods on page 153.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 usedwith any frequency reference source.Setting E: Motor temperatureIn addition to motor overload fault detection oL1, it is possible to use a PTC (Positive Temperature Coefficient)thermistor for motor insulation protection. Connect the PTC to analog input terminal A3, and set switch S4 on theterminal board to PTC. Refer to Terminal A3 Analog/PTC Input Selection on page 79 for details on setting S4. Refer toMotor Protection Using a Positive Temperature Coefficient (PTC) on page 247 for further explanation.Setting F, 1F: Through modeWhen set to F or 1F, an input does not affect any drive function, but the input level can still be read out by a PLC via acommunication option or MEMOBUS/Modbus communications.Setting 10, 11, 12, 15: Forward, Reverse, Regenerative, General torque limit (OLV, CLV, AOLV/PM, CLV/PM)These functions can be used to set a torque limit using analog inputs for different operating conditions. Refer to L7:Torque Limit on page 267 for details.Setting 13: Torque Limit Using Torque Reference/Speed LimitWhen using Torque Control, an analog input programmed to this function can set the torque reference (when in TorqueControl) or the torque limit (when in Speed Control). Refer to Setting the Torque Reference, Speed Limit, and TorqueCompensation Values on page 188 for details.Setting 14: Torque compensationUsed to set a torque compensation value when using Torque Control. Refer to Setting the Torque Reference, SpeedLimit, and Torque Compensation Values on page 188 for details.Setting 16: Differential PID FeedbackIf an analog value is set for this function, the PID controller is set for differential feedback. The subtraction of the PIDfeedback input value and the differential feedback input value builds the feedback value that is used to calculate the PIDinput. Refer to PID Feedback Input Methods on page 153.Setting 30, 31, 32: DriveWorksEZ Analog Input 1, 2, 3These settings are for functions used in DriveWorksEZ. Normally there is no need to change or apply these settings.◆ H4: Multi-Function Analog OutputsThese parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of driveperformance.■ H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor SelectionSets the desired drive monitor parameter U- to output as an analog value via terminal FM and AM. Refer to U:Monitor Parameters on page 291 for a list of all monitors. The “Analog Output Level” column indicates if a monitor canbe used for analog output.Example: Enter “103” for U1-03.
