Direction Control

Rockwell Automation Publication PFLEX-RM001H-EN-P - June 2013 91

PowerFlex 700 Firmware 3.001 (& later) Enhancements

Certain digital output enhancements have been included in firmware version

3.001 (and later) for the PowerFlex 700 Vector Control drive. These include:

• Digital output control via Datalink

Parameter Controlled Digital Outputs

Enables control of the digital outputs through the Data In parameters.

Example

Digital Output 2 controlled by Data In B1

Setup

• [Data In B1], parameter 302 = 379 ([Dig Out Setpt] as the Data In target)

• [Digital Out2 Sel], parameter 384 = 30 "Param Cntl"

When Bit 1 of Data In B1 =1 Digital Out 2 will be energized.

Direction Control Direction control of the drive is an exclusive ownership function. Thus only one

device can be commanding/controlling direction at a time and that device can

only command one direction or the other, not both. Direction is defined as the

forward (+) or reverse (–) control of the drive output frequency, not motor

rotation. Motor wiring and phasing determines its CW or CCW rotation.

Direction of the drive is controlled in one of four ways:

1. 2-Wire digital input selection such as Run Forward or Run Reverse (Figure

17 on page 86).

2. 3-Wire digital input selection such as Forward/Reverse, Forward or Reverse

(Figure 16 on page 86

3. Control Word bit manipulation from a DPI device such as a communications

interface. Bits 4 & 5 control direction. Refer to the Logic Command Word

information in Appendix A of the PowerFlex 70 or 700 User Manual.

4. The sign (+/-) of a bipolar analog input.

Direction commands by various devices can be controlled using the [Direction

Mask]. See page 113

for details on masks.

Refer to Digital Inputs

on page 70 and Analog Inputs on page 18 for more detail

on the configuration and operating rules for direction control.

INPUTS & OUTPUTS

Digital Outputs

379 [Dig Out Setpt]

Sets the digital output value from a communication device.

Example

Set [Data In B1] to “379.” The first three bits of this value will determine the setting of [Digital

Outx Sel] which should be set to “24, Param Cntl.”
