FM-3 Programming Module Reference Manual

Index.#.AtVel

This source activates when the target index velocity is reached. If Feedrate override is changed or FeedHold is activated AtVelocity shall remain active. Index.#.AtVel will deactivate at the start of any deceleration or acceleration. During a synchronized index, this source could be active even without any motor motion if the master axis stops.

Index.#.Command Complete

The Index.#.CommandComplete source will activate when the specific index completes its deceleration ramp. It will remain active until the specific index is initiated again. If the drive stop destination is used during an Index, then the Index.#.CommandComplete will not activate.

Index.#.Command In Progress

The Index.#.CommandInProgress source is active throughout an entire index profile. The source activates at the beginning of the index acceleration ramp, and deactivates at the end of the index deceleration ramp. During a synchronized index, this source could be active even without any motor motion if the master axis stops.

Index.#.Decelerating

This source is active while an index is decelerating from its’ target velocity. Once the index reaches zero velocity, or its’ next target velocity, the Index.#.Decelerating source will deactivate.

Index.#.LimitDistHit

Activated when the registration sensor is not found before the Limit Distance is traveled. If the Registration Window is enabled the sensor must be activated inside the window to be recognized.

Index.#.PLSStatus

Controlled by the PLSOn and PLSOff Points which are relative to the distance commanded since the start of the index. Activated when index distance command is in between the PLSOn point and PLSOff points.

Index.ProfileLimited

For timed indexes, if the values for Max. Velocity, Max. Acceleration, and Max. Deceleration are such that the distance cannot be covered in the specified time, the Index.ProfileLimited flag will activate when the index is initiated, indicating that the index cannot be performed as desired. The Index.ProfileLimited flag will remain active until cleared using the Index.ResetProfileLimited assignment or program instruction. In this situation, the index will still operate, but the time will be extended. In other words, the profile will be performed using the maximums values and still cover the specified distance, but not in the specified time.
