A10. REMOTE MAIN SPEED POTENTIOMETER
A remote Main Speed Potentiometer (5 k Ω) can be used in lieu of the Keypad or the Built-In
Potentiometer. The Main Speed Potentiometer can be connected for bidirectional, forward, or reverse
motor speed control, as described on page 52.
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 Table 16, for the Analog Outputs 1 and 2 Electrical Ratings.
Analog Output 1 – Connect the auxiliary device signal input to Terminal “15” and the common to
Terminal “16”, as shown in Figure 36. Set Analog Output 1 Mode (Function No. 8.06) for the desired
parameter to be monitored (factory set to Motor Frequency (“0000”)). Set Analog Output 1 Gain
(Function No. 8.07) for the desired signal gain (factory set to 100%). Analog Output 1 provides a 0 – 5
Volt DC signal output.
Analog Output 2 – Connect the auxiliary device signal input to Terminal “17” and the common to
Terminal “18”, as shown in Figure 36. Set Analog Output 2 Mode (Function No. 8.08) for the desired
parameter to be monitored (factory set to Motor Frequency (“0000”)). Set Analog Output 2 Type
(Function No. 8.09) to ((“0000”) (factory setting)) for 0 – 5 Volt DC output. Set Analog Output 2 Type
(Function No. 8.09) to “0001” for 0 – 20 mA DC output. Set Analog Output 2 Type (Function No. 8.09)
to “0002” for 4 – 20 mA DC output. Set Analog Output 2 Gain (Function No. 8.10) for the desired sig-
nal gain (factory set to100%).
