This setting requires PID operation to be enabled in b5-01. Refer to PID Feedback InputMethods on page 32.Setting C: PID SetpointSupplies the PID setpoint value and makes the frequency reference selected in parameter b1-01 no longer the PID setpoint.PID operation to be enabled in b5-01 to use this setting. Refer to PID Setpoint Input Methods on page 32.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 PID FeedbackIf an analog value is set for this function, the PID controller is set for differential feedback. The difference of the PID feedbackinput value and the differential feedback input value builds the feedback value used to calculate the PID input. Refer to PIDFeedback Input Methods on page 32.Setting 25: Secondary PI Setpoint10 V = S3-02 (Maximum Output Frequency).Setting 26: Secondary PI Feedback10 V = S3-02 (Maximum Output Frequency).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 164 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.No. Name Setting Range DefaultH4-01 Multi-Function Analog Output Terminal FM Monitor Selection 000 to 655 102H4-04 Multi-Function Analog Output Terminal AM Monitor Selection 000 to 655 103A setting of 031 or 000 applies no drive monitor to the analog output. With this setting, terminal functions as well as FM andAM output levels can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).1.7 H: Terminal FunctionsYASKAWA ELECTRIC SIEP C710636 10C Z1000U HVAC MATRIX Drive Programming Manual 1031 Parameter Details
