Select
Jog.Select0
This destination is used to select between the jogs. It is used along with the Jog.PlusActivate
and Jog.MinusActivate destinations. If the Jog.Select0 destination is not active then the Jog.0
setup parameters will be used for jogging. If the Jog.Select0 input function is active, the Jog.1
setup parameters will be used for jogging. If the Jog.Select destination is changed during
jogging motion the axis will ramp smoothly from the previously selected jog velocity to the
new jog velocity using the specified jog acceleration. This is level sensitive.
Stop
Jog.Stop
This is used only in programs to halt jogging motion. Jogging motion is initiated in programs
using the Jog.#.MinusActivate or Jog.#.PlusActivate instructions, and using the Jog.Stop will
cause the motor to decelerate to a stop at the Jog.#.Decel rate for the jog that is active.
Acceleration
Jog.#.Accel
This parameter is the average acceleration ramp for the specific jog.
Accelerating
Jog.#.Accelerating
This source is active while a jog is accelerating to its target velocity. Once the jog reaches the
target velocity, the Jog.#.Accererating bit will turn off.
At Velocity
Jog.#.AtVel
This source activates when the particular jog has reached its target velocity. It deactivates
when accelerating or decelerating to another target jog velocity.
Command Complete
Jog.#.CommandComplete
The Jog.#.CommandComplete source activates when the specific Jog completes its
deceleration ramp and reaches zero commanded speed. It deactivates when the specific Jog is
initiated again.
