6 Starting and Operating
26 Version: 1.3.0 MP136E U­651 Rotation Stage
INFORMATION
To generate the maximum force, it is necessary to run in when starting the U-651 and after
longer downtimes; refer also to "Influence of Downtimes on the Torque" (p. 41). The U-651
reaches its maximum torque after running in.

Command several motion cycles at low velocity to run in. The motion cycles should include
as many full rotations as possible.
INFORMATION
In a vacuum, there is no heat dissipation via convection.

Operate the vacuum version of the U-651 with 20 % lower motor power than specified in
"Motor power and lifetime" (p. 40) or reduce the duty cycle.
Refer to the "Motor Power" section (p. 38) for more information on operating conditions.
6.2 Starting and Operating the U­651
NOTICE
Wrong parameter settings!
If you use the software that is included in the scope of delivery of the controller (p. 10), the
operating parameters of the U-651 can be loaded from a positioner database. The positioner
database contains the default parameter values of your rotation stage for doing initial motion
testing during starting. Depending on the application, using the default parameter values (e.g.,
for P term, I term, D term, acceleration and velocity) can cause damage to the rotation stage,
especially when operated with heavy loads.

If possible: Start without a load first.

Always install the latest version of the positioner database onto your PC.
For starting with a load:

Before starting, make sure that the U-651 has been properly installed (p. 15).

For optimal performance of the moving axis, adjust the operating parameters of the
controller (e.g., P term, I term, D term, acceleration, velocity; refer to the controller
manual).

Save the new parameter values to a positioner database on the PC or to the nonvolatile
memory of the controller for future use (refer to the controller manual and the
PIMikroMove manual).
Requirements

You have read and understood the general notes on starting and operating (p. 23).

You have read and understood the user manual of the controller (p. 3).

When starting with a load: The U-651 has been properly installed (p. 15).

The controller (p. 10) and the required software have been installed. All connections on
the controller have been made (refer to the controller manual).
