FeedRateOverride

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.

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.

Gear Accel

Gear.Accel

This parameter sets the acceleration of the realtime gearing ramp. Gear.Accel units are in Follower Units/ Velocity Time Base/Acceleration Time Base. The Gear.Accel functions only when the follower is ramping its speed up to meet the Masters at the specified Gear.Ratio.

Gear Accel Enable

Gear.AccelEnable

Gear.AccelEnable is a Destination that when it is "on" allows a gear to run a specified accel ramp after the gearing command is turned on.

Gear Accelerating

Gear.Accelerating

If Gear.AccelEnable is activated, this source is activated during the time between Gear.Initate = On and Gear.AtVel = On.

Gear Activate

Gear.Activate

The Gear.Activate destination is used to start gearing from an assignment. It is a level-sensitive function, which means that as long as Gear.Activate is active, gearing will be in progress. When deactivated, gearing motion will come to a stop without deceleration. This function is only available through the assignments screen. When gearing from a program, the Gear.Initiate instruction is used.

Gear at Velocity

Gear.AtVel

The Gear.AtVel source indicates that the motor is running at the programmed gear ratio. In early releases of Gearing, acceleration and deceleration will not be used with gearing, so this source will always be active when gearing is active.

Gear Command Complete

Gear.CommandComplete

This source will activate when gearing has been stopped, and will remain active until the gear is initiated again. Gearing does not use a deceleration ramp, so this source will activate immediately after a Gear.Activate destination is deactivated.

Gear Command In Progress

Gear.CommandInProgrees

This source will activate when Gearing is initiated either from a program or through an assignment. The source will remain active as long as gearing is in operation. This source can be active even if the motor is not in motion as long as gearing is active.

Gear Decel

Gear.Decel

This parameter sets the deceleration of the realtime gearing ramp. Gear.Decel units are in Follower Units/ Velocity Time Base/Acceleration Time Base. The
