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 communication option or MEMOBUS/
Modbus communications (through mode).

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 1.72 illustrates how the gain and bias settings work.
Figure 1.72
Figure 1.72 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.

H5: MEMOBUS/Modbus Serial Communication
Through the drives built in RS422/485 port (terminals R+, R-, S+, S-), serial communication
can be performed with programmable logic controllers (PLCs) or similar devices using the
MEMOBUS/Modbus protocol.
