The scaling of the trend’s y-axis is color-coded to the signal and can be re-
selected by clicking on the desired range’s color bar on the right-hand side of the
chart. For example clicking on the blue bar next to ‘Position Setpoint’ in Figure
6-6 will change the y-axis scaling to the position setpoint range, 0 % to 100 % in
this case.
Estimated Torque is displayed in units of percentage of steady state (continuous)
torque and is based on the current commanded to the actuator coil. During
transients the torque/current limit may be as much as twice the steady state
value for a short period of time. The actual torque varies with the actuator model,
values are specified in the Appendix under ‘Torque output’.

Trend options can be modified by selecting the Properties button, which opens
the Strip Chart Properties window (Figure 6-8). From this window, the chart
period, colors, ranges, and grid options can be modified. Individual ranges can
be modified by selecting the desired signal (Actual Position, Position Setpoint,
Estimated Current) from the pen drop-down selection and modifying the
attributes of that signal (e.g., min range, max range, color). Each signal can have
different ranges.
