Velocity Loop
In order to adjust properly, connect an oscilloscope to Analog Output 1 Terminal 21
(Velocity Feedback). Using the HMI, temporarily set the
Ramp Bypass (305) parameter
to True. Run the drive and apply a step change to the external speed reference. Observe
the response to the drive. The motor speed should respond quickly with minimum
overshoot. Adjust the
Velocity Proportional Gain (201) and Velocity Integral Time
(202) parameters to obtain a critically damped waveform as seen in Figure 6. Increasing
the proportional gain improves the response but increases the overshoot. Reducing the
integral time improves the response but can cause instability if set too low. Once
complete, return
Ramp Bypass (305) to False.

6.7 Password Protection
If password protection is required, set the appropriate passwords under the Setup|Security
section.
Programming & Adjustments
Programming and adjustment of the Elite Pro is accomplished by
changing parameter settings. Each parameter has a descriptive
name and a tag (or number) identifier. Parameters are grouped
together in blocks according to their function. The following
sections contain each software block diagram and descriptions of
each parameter function. Refer to Figure 7 for key conventions
that are used in the block diagrams. Each parameter is one of
three types: Read-Only (RO), Inhibit Change while Running (ICR),
or Read-Write (RW). ICR parameters can be changed only when
the drive is in the Stop mode.
Note: When parameters are altered, the changes must be saved,
