only available through the Assignments view. When gearing from a program, the Gear.Initiate and Gear.Stop instruction are
used to start and stop gearing.
The gearing function must be stopped by the same method that started it. If it is started from an assignment, then it must be
stopped from an assignment or if started in a user program, it must be stopped in a user program.
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. 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 Gear.Decel functions only when the follower is ramping its speed down after the gearing function
has turned off.
Gear Decel Enable
Gear.DecelEnable
Gear.DecelEnable is a Destination that when it is "on" allows a gear to run a specified decel ramp after the gearing command
is turned off.
Gear Decelerating
Gear.Decelerating
If Gear.DecelEnable is activated, this source is activated during the time between Gear.Initate = Off and
Gear.CommandComplete = On.
Gear Initiate
Gear.Initiate
Gearing can be activated through an assignment, or from a program instruction, Gear.Initiate. If initiated from an assignment,
the Gear.Activate destination is a level-sensitive event. This means that gearing will be active as long as the source to which it
is assigned is active. If gearing from a user program, the Gear.Stop instruction is used to stop the gearing motion. The gearing
function must be stopped by the same method that started it. If it is started from an assignment, then it must be stopped from
an assignment or if started in a user program, it must be stopped in a user program.
Gear Recovery Distance
Gear.RecoveryDist
This variable measures the distance the follower loses from the master. This distance lost is measured between a Gear Initiate
and the Gear At Velocity.
Gear Stop
Gear.Stop
Gear.Stop will stop gearing motion that has been initiated from a program using Gear.Initate.
Graph Run
GraphRun
This instruction allows the user to enable the graph from a user program. It is similar to pressing the Run button on the Graph
