Chapter 7 Bulletin 280E/281E/284E Programmable Parameters

Comm Write Mode

Determines whether parameter

changes made over communication

port are saved and stored in Non-

Volatile Storage (NVS) or RAM only. If

they are stored in RAM, the values will

be lost at power-down.

0 = Save (Default)

1 = RAM Only

Parameter Number 264

Access Rule GET/SET

Data Type BOOL

Group Drive Advanced Setup

Units —

Minimum Value 0

Maximum Value 1

Default Value 0

ATTENTION: Risk of equipment damage exists. If a controller is programmed to write

parameter data to Non-Volatile Storage (NVS) frequently, the NVS will quickly exceed its

life cycle and cause the drive to malfunction. Do not create a program that frequently

uses configurable outputs to write parameter data to NVS unless Parameter 264 (Comm

Write Mode) is set to Option 1.

PID Invert Error

When set to “Inverted”, changes the

sign of the PID error. This causes an

increase in the drive output frequency

with PID Feedback greater than PID

Setpoint, and a decrease in drive

output frequency with PID Feedback

less than PID Setpoint.

0 = Not Inverted (Default)

1 = Inverted

Parameter Number 267
