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.

All Jog destinations are level sensitive.
