A9. ANALOG SIGNAL OUTPUT

Two analog signal outputs are provided, which will linearly follow the parameter programmed in Analog output

1 Mode (Function No. 8.06) and Analog Output 2 Mode (Function No. 8.08). They can be used to monitor

Motor Frequency, Set Frequency, Motor Voltage, Bus Voltage, and Motor Current. See Figure 34, on page

44, for Analog Output 1 and 2 Gain settings (factory set to 100%). See Table 26, for Analog Outputs 1 and 2

electrical ratings. See Table 27, on page 44, for drive programming. See Figure 35, on page 44, for

connections.

Analog Output 1 provides a voltage signal output. Analog Output 2 provides a voltage or current signal output.
