EZInput Force

considered active in the SM-EZMotion firmware. Once the input has been active for the debounce time, a rising edge on the input will occur in the SM-EZMotion module. This parameter can be found on the EZMotion I/O Setup view.

EZInput Force

EZInput.#.Force

The digital inputs on the SM-EZMotion module can be forced On or Off within a user program. To do so, the Force Enable event for the desired input must first be activated. Once the Force Enable for the input is active, the input can be forced on or off using the following instructions:

EZInput.#.Force = ON

EZInput.#.Force = OFF

Forcing an input On or Off does not prevent it from changing state again. It is solely a means of changing the state from within a user program.

EZInput Force Enable

EZInput.#.ForceEnable

EZInput.#.Force must be active to force a specified input on or off in a user program. See EZInput Force above for further information.

EZInput Status

EZInput.#.In

EZInput.#.In is the status of the specified digital input on the SM-EZMotion module. The “.In” at the end of the parameter is optional, so this signal is most often referred to simply as EZInput.#. This signal can be used in a user program or on the Assignments view. These inputs are updated at the Trajectory Update Rate specified on the Setup view.

These inputs are also used for the high-speed capture functionality. The SM-EZMotion is capable of capturing the motor position, master encoder position, and time within 1 µsec of the rising edge of the EZInputs.

EZOutput Name

EZOutput.#.Name

Each digital output on the SM-EZMotion module can be given a name. The name can be used in a user program to reference a specific input. The name can be up to 12 alphanumeric characters, but must begin with a non-numeric character.

EZOutput State

EZOutput.#.Out

EZOutput.#.Out is used to change the state of a specific digital output on the SM-EZMotion module. The “.Out” at the end of the parameter name is optional, so this signal is

often referred to simply as EZOutput.#. In a user program, EZOutput.#.Out is set On or Off to activate or deactivate the digital outputs. From the Assignments view, any Source can be assigned to the EZOutputs to activate them automatically.

Drive OK

Fault.DriveOK

Active when there are no faults. Inactivated when any fault except travel limits occur. Drive enable has no effect on this event.

Enable Feedforwards

FeedforwardsEnable

This parameter may be setup on the Tuning view or through a program, and enables feedforward compensation. When feedforwards are enabled, the accuracy of the Inertia and Friction settings are very important. If the Inertia setting is larger than the actual inertia, the result could be a significant overshoot during ramping. If the Inertia setting is smaller than the actual inertia, following error during ramping will be reduced but not eliminated. If the Friction is greater than the actual friction, it may result in velocity error or instability. If the Friction setting is less than the actual friction, velocity error will be reduced, but not eliminated.

Feedhold

Feedhold

When this destination is activated the motor will decelerate to a stop in the time specified by the FeedholdDecelTime parameter. When it is deactivated the motor will accelerate back up to the programmed speed in the same amount of time. It is used to hold motion without cancelling the move in progress. If a feedhold is activated during an index the motor will 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
