FeedRate Deactivate

FeedRateDeactivate

This destination allows the user to deactivate the FeedRate Override feature. When FeedRate Deactivate is enabled, FeedRate

Override will be disabled and all index or home motion will operate at its programmed velocity. When FeedRate Deactivate

is disabled, FeedRate Override will be enabled, and index and home motion is subject to scaling by the FeedRate Override

parameter. The default value for FeedRate Override is 100%, so even when FeedRate Override is enabled, default motion

will run at programmed velocity.

FeedRate Override

FeedRateOverride

This parameter is used to scale all motion. It can be described as “scaling in real time.” The default setting of 100% will allow

all motion to occur in real time. A setting of 50% will scale time so that all motion runs half as fast as it runs in real time. A

setting of 200% will scale time so that all motion runs twice as fast as it would in real time. FeedRate Override is always

active, and this parameter may be modified via Modbus or in a program. When changed, the new value takes effect

immediately.

Foldback Active

FoldbackActive

This source (output function) is active when the drive is limiting motor current. If the Foldback RMS exceeds 100 percent of

the continuous rating, the current foldback circuit will limit the current delivered to the motor to 80 percent of the continuous

rating.

Foldback RMS

FoldbackRMS

This read-only parameter accurately models the thermal heating and cooling of the drive. When this parameter reaches 100

percent, current foldback will be activated.

Following Error

FollowingError

Following Error displays the difference between the Position Command and the Position Feedback.

Enable Following Error

FollowingErrorEnable

This parameter can be setup from the Position view or from a program. When enabled, a following error fault will be

generated if the absolute value of the Following Error exceeds the Following Error Limit.

Following Error Limit

FollowingErrorLimit

This parameter is used when the FollowingErrorEnable bit is set. This limit is compared to the absolute value of the

FollowingError. If the FollowingError is greater than the FollowingErrorLimit, a following error fault will be generated.

Friction

This parameter is characterized in terms of the rate of friction increase per 100 motor RPM. If estimated, always use a

conservative (less than or equal to actual) estimate. If the friction is completely unknown, a value of zero should be used. A

typical value used here is less than one percent.
