FM-3 Programming Module Reference Manual

to the programmed speed in the same amount of time. It is used to hold motion without

cancelling the move in progress. If a feedhold is activated during an index the motor will

come to a halt, but the index's velocity command remains at the velocity it was at before the

feedhold was activated. When the feedhold is deactivated time will ramp back up and the

index will continue on to its programmed distance or position. Feedhold affects indexes,

homes, and programs. A jog is not affected by the feedhold unless it is initiated from a

program. This is level sensitive.

Feedhold Deceleration Time FeedholdDecelTime

When Feedhold destination is activated the motor will decelerate to a stop in the time

specified by the FeedholdDecelTime parameter. While the feedhold destination is active, the

motion profile is stopped.

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 moves run half as fast as they do at 100%. A setting of 200% will scale time

so that all moves run twice as fast as they would at 100%. Feed Rate 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 RMSexceeds 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.
