Epsilon EP-P Drive and FM-3/4 Module Reference Manual

If the Registration Offset distance is in the opposite direction from the move, or is so short that the motor cannot stop in the

specified distance at the programmed deceleration rate, the motor will decelerate with the programmed ramp, and then back-

up to the specified position (registration point + the Registration Offset).

Index Sources and Destinations

Sources

Index.AnyCommandComplete

Active when any index motion command is completed. If a stop is activated before the index has completed, this destination

will not activate. Deactivated when any new index command is initiated.

Index.#.Accelerating

This source is active while an index is accelerating to its’ target velocity. Once the index reaches the target velocity, or begins

to decelerate, the Index.#.Accelerating source will deactivate.

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.

Destinations

Index.ResetProfileLimited

If a timed index was not able to complete in the specified time, the Index.ProfileLimited source will activate.

Index.ResetProfileLimited is used to clear the ProfileLimited flag and acknowledge that the index did not complete in the

specified time. This can be activated through an assignment, or through a user program. This function is edge-sensitive, so

holding it active will not prevent ProfileLimited from activating.
