Control Wiring for PowerFlex 700S Drives with Phase I Control 3-9

Analog Outputs

+/-10V dc or +/-1.0V dc

Used to drive analog meters

displaying speed and current

Analog Outputs Indicating Motor Speed and Motor Current Example: Using Analog Output 1, -10V to +10V

to meter Motor RPM and direction:

• Adjust Parameter 812 [Anlg Out1 Offset] so that

minimum speed creates a minimum signal (if

the minimum speed is zero and the minimum

signal is zero, enter a zero)

• Adjust Parameter 817 [Anlg Out1 Scale] so that

the maximum speed creates a maximum signal

(if the maximum speed is 100% of motor base

speed and the maximum signal is 10V dc, enter

a value of 0.1)

• Send the data to the Analog Output: Par 815

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

300 [Motor Spd Fdbk] (the source)

Example: Using Analog Output 2, -10V to +10V

to meter Motor Current

• Adjust Parameter 813 [Anlg Out2 Offset] so that

minimum current creates a minimum signal (if

the minimum current is zero and the minimum

signal is zero, enter a zero)

• Adjust Parameter 822 [Anlg Out2 Scale] so that

the maximum current creates a maximum signal

(if the maximum current is 200% of motor NP

FLA and the maximum signal is 10V dc, enter a

value of 2.0)

• Send the data to the Analog Output

Par 820 [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 (Par2 [Motor NP

FLA]/10V Output)
