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
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.
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
