Acceleration Time Scale AccelUnits.TimeScale
This parameter is the time units for accel./decel. ramps. Possible selections are milliseconds
or seconds.
At Velocity AtVel
This source is active when the FM-3 is executing a constant velocity motion segment. One
example would be during an index. The source would activate after the motor has finished
accelerating up to speed and before the motor begins to decelerate to a stop. A normal index
consists of 3 segments: Accelerating, At Velocity, and Decelerating. This source is active
during the At Velocity segment, and is activated based on the commanded velocity, not the
feedback velocity. During synchronized motion, AtVel can be active without actual motor
movement.
Brake Activate Brake.Activate
This destination, when activated, engages the brake. This is simply used to manually engage
the brake outside of the normal brake operation. This is level sensitive.
Brake Disengaged Brake.Disengaged
This source is used to control the motor holding brake. When it is "off" the brake is
mechanically engaged. When the brake is engaged, the diagnostic display on the front of the
drive will display a "b". The drive and module outputs are limited to 150 mA capacity,
therefore, a suppressed relay is required to control the brake coil. Model BRM-1 may be used.
Brake Release Brake.Release
This destination will release the brake under all conditions, even when Brake.Activate is
engaged. When this input function is active, the Brake.Disengaged output function (source)
will be activated. This is used as a manual brake override.This is level sensitive.
Commanding Motion CommandingMotion
This source activates when VelCommand is non-zero.
Decelerating
This source is active when the FM-3 is decelerating. A normal index consists of 3 segments:
Accelerating, At Velocity, and Decelerating. Decelerating follows the accelerating segment
and the At Velocity segment. When indexes are compounded to create a complex motion
profile, only the last index may contain a decelerating segment.
