Scope Variable
Definition
Position Error [F3]
Position Error (also referred to as "Tracking Error") displays
the difference between commanded position and actual
position.
Velocity, Commanded
[F4]
Commanded Velocity displays the actual commanded velocity
vs. time motion profile coming from your controller or MSP.
Torque, Measured [F5]
Measured Torque graphs the actual torque that the motor is
using during (as a percentage of peak torque).
Torque Utilization [F6]
Torque Utilization plots the percentage of
available
peak
torque in use over time. This is particularly useful if you have
a power limited motor and need to know how close to
available peak torque the motor is operating.
Velocity Error (Gated)
Velocity Error shows the difference between commanded
velocity and actual velocity during constant velocity
command.
Bus Voltage
Bus Voltage displays ClearPath's DC bus voltage in real time.
Max Phase Voltage
Max Phase Voltage displays the greatest voltage running
through ClearPath's phase wires.
Torque, Commanded
Commanded torque displays the required torque to complete
the given command from your controller or MSP.
Position, Measured
Measured Position displays the actual position of ClearPath in
terms of encoder counts.
Acceleration,
Commanded
Commanded Acceleration shows the actual acceleration
command coming from your controller or MSP.
Jerk, Commanded
Commanded Jerk displays the derivative of the commanded
acceleration.
Torque Error (peak)
Torque Error displays the difference between commanded and
actual torque.
Velocity, Measured
Measured Velocity displays ClearPath shaft velocity in either
RPM or encoder counts per second.

The Vertical Scale
lets you change the scale of the amplitude axis in
terms of units per division. This allows you to control how a waveform fits
(vertically) on the Scope display.
4
Envelope Mode
allows you to capture the minimum and maximum
amplitude envelope of a displayed variable, typically generated over many
sweeps of the scope.
Important note: To use Envelope Mode, you must be on Channel 1,
and running a repeat move, and have the scope's trigger mode set to
"Normal".
