4. From the Load Type pull-down menu, choose the appropriate load type.
5. Enter the Scaling Units.
6. From the Travel Mode pull-down menu, choose the appropriate Travel
Mode.
See Scaling on page 222
for more information.
7. Click Apply.
When you select No Feedback, the
Motor Feedback dialog box does not
appear.
In this case, the drive has already
been configured for the motor by the
DriveExecutive™ software or the HIM
configuration tools.
For scaling with Feedback = [No Feedback], the
denominator of the Scaling factor is forced to
have fixed units = [Motor Rev/s] because the
controller internally simulates the Feedback
(Configuration =[No Feedback]).
