Actual Line Voltage, the maximum power the 5 HP, 460V motor can produce is3.7 HP

at 44.6 Hz.

13.19 Analog Inputs

13.19.1 Possible Uses of Analog Inputs

The analog inputs provide data that can be used for the following purposes:

• Provide a value to Speed Ref A or Speed Ref B.

• Provide a trim signal to Speed Ref A or Speed Ref B.

• Provide a reference when the terminal block has assumed manual control of the

reference

• Provide the reference and feedback for the PI loop. Refer to Process PI Loop in

section 2.3.19.

• Provide an external and adjustable value for the current limit and DC braking level

• Enter and exit sleep mode.

• Provide a value to Torque Ref A or Torque Ref B.

13.19.2 Analog Input Configuration

Anlg In Config (320)

Current Lmt Sel (147) allows an analog input to control the set point while DC Brk Levl

Sel (157) allows an analog input to define the DC hold level used when Ramp-to-Stop,

Ramp-to-Hold, or Brake-to-Stop is active.

To provide local adjustment of a master command signal or to provide improved

resolution the input to analog channel 1 or 2 can be defined as a trim input. Setting

Trim In Select (117) allows the selected channel to modify the commanded frequency

by ±10%. The speed command will be reduced by 10% when the input level is at Anlg

In x Lo with it linearly increasing to 10% above command at Anlg In x Hi.
