H4: Multi-Function Analog Outputs - YASKAWA L1000A Technical Manual

5.7 H: Terminal Functions
Setting 1F: Not used (Through mode)
When set to 1F, an input does not affect any drive function, but the input level can still be read out by a PLC via a
communication option or MEMOBUS/Modbus communications.

◆ H4: Multi-Function Analog Outputs

These parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of drive
performance.

A setting of 031 or 000 applies no drive monitor to the analog output. With this setting, terminal functions as well as FM
and AM output levels can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).

H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias
H4-05, H4-06: Terminal AM Gain and Bias
Parameters H4-02 and H4-05 set the terminal FM and AM output signal level equal to 100% of the monitor (gain).
Parameters H4-03 and H4-06 set the bias added to the monitor output for terminals FM and AM. Both are set as a
percentage, where 100% equals 10 Vdc analog output. The output voltage of both terminals is limited to 10 Vdc.
Select an output signal range between 0 to +10 Vdc or -10 to +10 Vdc using parameters H4-07 and H4-08.

Using Gain and Bias to Adjust Output Signal Level
When viewing a gain setting parameter (H4-02 or H4-05) on the digital operator, the analog output will supply a voltage
signal equal to 100% of the monitor value (including changes made from bias and gain settings). When viewing a bias
setting parameter (H4-03 or H4-06), the analog output voltage will supply a signal equal to 0% monitor value (including
changes made from bias and gain settings).
Example 1: Set H4-02 to 50% for an output signal of 5 V at terminal FM when the monitored value is at 100%.
Example 2: Set H4-02 to 150% for an output signal of 10 V at terminal FM when the monitored value is at 76.7%.
