Communications

• Supports Drive Serial Interface (DSI)

communication modules (DeviceNet™,

EtherNet/IP™, PROFIBUS™DP,

LonWorks®, BACnet®) and accessories.

• Embedded Modbus RTU, P1-FLN and

Metasys N2 protocols are parameter

selectable and require no additional

hardware or software.

•Integral RS485 communications can be

used for programming from a PC. It can also

be used in a multi-drop network

configuration. A serial converter module

provides connectivity to any controller with a

DF1 port.

PC Programming Software

Through the use of a Serial Converter Module and DriveExplorer™

or DriveTools™SP software, programming can be greatly simplified.

DriveExplorer Software

• View and modify drive and adapter parameters in a method similar to

the file management capability of Microsoft Windows Explorer.

• Operate the drive via an on-screen Control Bar, which is a tool that

allows you to start, stop, and change the speed reference of the drive.

• Save, restore and print parameter information.

• Compare current parameters with factory defaults or previously saved

parameter values.

• Edit, upload and download parameters.

DriveTools SP Software

• Online and offline programming capability.

• In-grid and dialog-based parameter editing.

• Immediate visual indication of drive and communication status when

viewing online drive.

• Integrated HTML Help architecture.

Configurable Keypad Hand-Off-Auto Functions

Parameter P042 [Auto Mode] defines the operating configuration of the

control keys.

Hand-Off-Auto Configuration

Hand Mode: Start command and speed reference come from the integral

keypad. Auto key switches control from Hand mode to Auto

mode in a bumpless transfer as long as there is an active run

command.

Auto Mode: Start command is defined by P036 [Start Source] (keypad,

terminal block, comm port) and speed reference is defined

by P038 [Speed Reference] (analog inputs, preset frequency,

comm port). Start/Hand key switches control and speed

reference to the integral keypad in a bumpless transfer.

Local/Remote Configuration

Local Mode: Start command and speed reference come from the integral keypad. Auto key stops the drive and the drive

switches to Remote mode.

Remote Mode:Start command is defined by P036 [Start Source] and speed reference is defined by P038 [Speed

Reference]. Auto key stops the drive and the drive switches to Local mode.

Auto/Manual Configuration

Manual Mode:Start command is defined by P036 [Start Source] and the speed reference comes from the integral keypad.

Auto key toggles frequency control to Auto mode in a bumpless transfer.

Auto Mode: Start command is defined by P036 [Start Source] and speed reference is defined by P038 [Speed

Reference]. Auto key switches frequency control to the integral keypad in a bumpless transfer.

Connectivity to Building Fire and Life Safety Systems

Purge

The PowerFlex 400 drive has an input which can be wired to a fire control panel or other fire/life safety systems allowing

control of the drive to be overridden. A purge input will start the drive at a programmable purge speed regardless of the

selected start source. Purge can occur and is operational at any time whether the drive is running or stopped. A purge

command will take precedence over a stop command from the comm port/network and over a “SW Enable” command from

the terminal block.

Fire/Freeze Status

The PowerFlex 400 drive can be tied into fire alarm systems or interlocked with cooling coils via a “Function Loss” input on

the drive. Upon opening of the input, the drive will immediately coast to a stop if running and issue a fault. The drive will

only be allowed to restart once the alarm state is cleared and the drive fault is reset.

Proportional, Integral, Differential Control Loop

The PowerFlex 400 has a built-in PID (Proportional, Integral, Differential) control loop. The PID loop is used to maintain a

process variable, such as pressure or flow, at a desired set point. The PID loop works by subtracting the PID feedback from

a reference and generating an error value. The PID loop reacts to the error, based on the PID gains, and outputs a frequency

to try to reduce the error value to zero.

Damper Control

The PowerFlex 400 allows damper control logic to be imbedded within the drive reducing cost associated with external

control hardware and software. A system Run command can be wired directly into one of the drive inputs. Relay outputs

can be used to energize the damper to either open or close. A damper limit switch can be wired back to the drive providing

indication that the damper is in the proper position and that it is safe for the drive to run at commanded speed.

Auxiliary Motor Control

The PowerFlex 400 has a built in Auxiliary Motor Control feature. This feature allows operation of up to three (3) line-

started motors in addition to the motor controlled directly by the PowerFlex 400 drive. System output can vary from 0%

(auxiliary motors off and drive-controlled motor at zero speed) to 400% (3 auxiliary motors and drive-controlled motor at full

speed). When Auxiliary Motor Control is enabled, the internal PID controller in the PowerFlex 400 uses a reference and

feedback signal to adjust the speed of the drive controlled motor such that the feedback signal follows the reference

signal. When demand exceeds the first motors capacity, the PowerFlex 400 Auxiliary Motor Control automatically starts an

auxiliary motor. The speed of the drive controlled motor is reduced to account for the auxiliary motors additional output to

the system. If demand continues to increase, the PowerFlex Auxiliary Motor Control starts additional motors using the

same process. When demand decreases, an auxiliary motor is stopped and the PowerFlex Auxiliary Motor Control

increases the speed of the drive controlled motor to account for lost system output. A Motor Interlock input identifies

motors that are out of service and causes them to skipped over to the next available motor.

An AutoSwap function also can be used which allows equal wear to be placed on each motor by periodically swapping the

drive controlled and auxiliary motors. Each motor in the system will over time be connected to the PowerFlex 400 drive and

also directly to the AC line. During an AutoSwap, the motor directly connected to the PowerFlex 400 drive is stopped and

the contactor is opened. The contactor of the next motor that will be controlled by the PowerFlex 400 drive is opened if

running across the AC line. A contactor is closed connecting this motor directly to the PowerFlex 400 drive and is started.

An additional motor is line started if required.
