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.
Jog Acceleration
Jog.#.Accel
This parameter is the average acceleration ramp for the
specific jog.
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.
Jog 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.
Jog 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.
Jog Command In Progress
Jog.#.CommandInProgress
The Jog.#.CommandInProgress source is high throughout
an entire jog profile. The bit goes high at the start of a jog
acceleration ramp, and turns off at the end of a jog
deceleration ramp.
Jog Deceleration
Jog.#.Decel
This parameter is the average deceleration ramp for the
specific jog.
Jog Decelerating
Jog.#.Decelerating
This source turns on at the beginning of a jog deceleration
ramp and turns off at the completion of the ramp.
Jog Initiate Minus
Jog.#.MinusInitiate
This is used inside a program to initiate a specific jog.
When this bit is active, jogging motion will be initiated in the
negative direction at the specified jog velocity.
Jog Initiate Plus
Jog.#.PlusInitiate
This is used inside a program to initiate a specific jog.
When this bit is active, jogging motion will be initiated in the
positive direction at the specified jog velocity.
Jog Time Base
Jog.#.TimeBase
The time base selects either realtime, which allows
velocities, acceleration and deceleration to be based on
real time, or synchronized, which allows for an external
synchronization signal.
Jog Velocity
Jog.#.Vel
This parameter specifies the velocity used for jogging with
the Jog.PlusActivate and Jog.MinusActivate destinations
or the Jog.#.PlusInitiate and Jog.#.MinusInitiate inside a
program. The units for this parameter are specified in the
User Units view.
Master Axis Encoder Revolution Counter
MasterAxis.MasterEncRevCount
This read-only parameter displays the number of whole
revolutions that the master encoder signal has moved
since powered up (absolute) and can be found on the
Online tabs on the Status and Master Setup views. The
units for this parameter are always revolutions since those
are the units used by the Unidrive SP and its’ option
modules. The value for this parameter comes from
parameter x.04 of the feedback module menu.
In order for this parameter to work properly, a master
encoder must be connected to a position feedback module,
and the MasterAxis.SpeedFeedbackSelector must be
configured properly.
Master Axis Encoder Position
MasterAxis.MasterEncRevPosition
This read-only parameter displays the number of fractions
of a revolution that the master encoder signal has moved,
and can be found on the Online tabs of the Status and
Master Setup views. The units for this parameter are
always 1/(2^16) of a revolution since those are the units
used by the Unidrive SP and its’ option modules. The value
for this parameter comes from parameter x.05 of the
feedback module menu.
In order for this parameter to work properly, a master
encoder must be connected to a position feedback module,
and the MasterAxis.SpeedFeedbackSelector must be
configured properly.
