Jog Name

This is a descriptive character string which can be assigned to the specific jog. Giving a name to a jog can make the motion setup easier to follow.

Time Base

This list box allows the user to select the time base for the individual jog. The options are Realtime and Synchronized.

Jog Velocity

This parameter specifies the target jog velocity for the individual Jog. The motor will run at this velocity when jogging with an assignment or through a program. This value is a signed number. The direction of the jog is determined by the sign of the jog velocity as well as using the Jog.PlusInitiate or the Jog.MinusInitiate.

Jog Acceleration

This is the acceleration ramp used when initiating this individual Jog. If S-Curve ramps are used, then this is the average acceleration rate for the entire ramp. The units for the acceleration are setup in the Setup - User Units view in PowerTools Pro.

Jog Deceleration

This is the deceleration ramp used when stopping this individual Jog. If S-Curve ramps are used, then this is the average deceleration rate for the entire ramp. The units for the deceleration are setup in the Setup - User Units view in PowerTools Pro.

Jog Sources and Destinations

Sources

Jog.AnyCommandComplete - The Jog.AnyCommandComplete source will activate when either Jog0 or Jog1 completes its deceleration ramp, and reaches zero commanded velocity. It will deactivate when any Jog is initiated again. If the Stop destination is used during a Jog, then the Jog.AnyCommandComplete will not activate.

Jog.#.Accelerating - This source is active while a jog is accelerating to its target velocity. Once the Jog reaches the target velocity, the Jog.#.Accelerating source will deactivate.

Jog.#.AtVel - This source activates when the individual jog reaches its target velocity. It deactivates when a jog deceleration ramp begins.

Jog.#.CommandInProgress - The Jog.#.CommandInProgress source is active throughout an entire jog profile. The source activates at the beginning of a jog acceleration ramp, and deactivates at the end of a jog deceleration ramp.

Jog.#.CommandComplete - The Jog.#.CommandComplete source will activate when the specific jog completes its deceleration ramp. It will remain active until the specific jog is initiated again. If the Stop

destination is used during a Jog, then the Jog.#.CommandComplete will not activate.

Jog.#.Decelerating - This source is active while a jog is decelerating from its target velocity. Once the Jog reaches zero velocity (or its new target velocity), the Jog.#.Decelerating source will deactivate.

Destinations

The following destination functions can be found in the Assignments view under the I/O setup group:

Jog.PlusActivate

When this destination is activated, jogging motion will begin in the positive direction. The jog velocity is determined by which jog (Jog0 or Jog1) is active or not. A jog stops when this destination is deactivated. If the jog velocity is negative, Jog.PlusActivate will cause the motor to jog in the negative direction.

Jog.MinusActivate

When this destination is activated, jogging motion will begin in the negative direction. The jog velocity is determined by which jog (Jog0 or Jog1) is active or not. A jog stops when this destination is deactivated. If the jog velocity is negative, Jog.MinusActivate will cause the motor to jog in the positive direction.

Jog.Select0

This destination is used to select between Jog0 and Jog1. When the Jog.Select0 destination is not active, the target velocity for the jog is the Jog.0.Velocity. If the Jog.Select0 destination is active, the target velocity of the jog is the Jog.1.Velocity. Jog.Select0 can be toggled "On" or "Off" while jogging. Jog acceleration and deceleration ramps are used to ramp between jog velocities.

Below is a description of jog operation using these destinations.

Note

In the table below Jog.0.Velocity = 100 RPM and Jog.1.Velocity = -500 RPM.
