±10V DC Analog Outputs

Using Analog Output 1: ±10V to meter Motor RPM and direction:

• Send the data to the Analog Output parameter:

Par 833 [Anlg Out1 Real] (the destination) linked to Par 71 [Filtered

SpdFdbk] (the source)

• Scale the output to the source parameter:

Par 835 [Anlg Out1 Scale] = 175 (Par 4 [Motor NP RPM] = 1750 /

10V)

Using Analog Out 2: ±10V to meter Motor Current:

• Send the data to the Analog Output parameter:

Par 840 [Anlg Out2 Real] (the destination) linked to Par 308 [Output

Current] (the source)

• Scale the output to the source parameter:

Par 822 [Anlg Out2 Scale] = xx (Par 2 [Motor NP FLA] / 10V output)
