5.6 H: Terminal Functions n H3-13: Analog Input Filter Time Constant Parameter H3-13 sets the time constant for a first order filter that will be applied to analog input A1 and also to the reference value from potentiometer option (AI-V3/J). An analog input filter can be used to prevent erratic drive control when a “noisy” analog reference is used. The drive operation becomes more stable the longer the time programmed, but it becomes less responsive to rapidly changing analog signals. u H4: Multi-Function Analog Output Terminal AM These parameters assign a function to analog output terminal AM for monitoring a specific aspect of drive performance. n H4-01:
Multi-Function Analog Terminal AM Monitor Selection Sets the desired drive monitor parameter U - to output as an analog value via terminal AM. Refer to U: Monitors on page 181 for a list of all monitors. The “Analog Output Level” columns indicates if a monitor can be applied for analog output. Example: Enter “103” for U1-03. A setting of 031 or 000 applies no drive monitor to the analog output. With this setting the terminal AM output level can be set by a PLC via a MEMOBUS/Modbus communications interface (through mode). n H4-02/H4-03: Multi-Function Analog Output Terminal AM Gain/Bias Parameter H4-02 sets the output voltage that is equal to 100% of the monitor value.
Parameter H4-03 sets the output voltage equal to 0% of the monitor value. Both values are set as a percentage of 10 V. The minimum output voltage for terminal AM is 0 V, the maximum is 10 Vdc. Figure 5.32 illustrates the function of the gain and bias settings. Bias 30% Gain 100% Terminal AM output voltage 10 V Gain 150% Bias 0% Terminal AM output voltage 10 V 5 V Gain 100% Bias 0% 3 V Bias 0% Gain 100% Parameter Details 0 V Gain 50% Bias 0% 0 V 100% Monitor value 0% 100% Monitor value 0% Figure 5.32 Analog Output Gain/Bias Setting When viewing the settings for H4-02, terminal AM will output a voltage that is equal to 100% of the monitor value (considering the present setting).
When viewing the settings for H4-03, terminal AM will output a voltage that is equal to 0% of the monitor value. 5 u H5: MEMOBUS/Modbus Serial Communication Through the drives optional RS-422/485 interface, serial communication can be performed with programmable logic controllers (PLCs) or similar devices using the MEMOBUS/Modbus protocol. The H5- parameters are used to set up the drive for MEMOBUS/Modbus Communications. Refer to MEMOBUS/ Modbus Serial Communication on page 191 for detailed descriptions of the H5- parameters.
