FM-3 Programming Module Reference Manual
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 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.
