15. Run the Field Weakening test.
Run the Field Weakening Drive test.
Note: e present Field Weakening Drive value (0%) was determined by
the auto-characterization procedure, and is not the default value (50%).

Field Weakening Drive
Increasing the parameter toward 100% will progressively allow more torque
(along with more current) at high motor speeds, but increasing it too much
will actually reduce performance while still driving a great deal of current.
While the most ecient operation will occur with eld weakening at the
0% auto-characterization value, more torque at high speeds may be required,
necessitating more eld weakening.
On the 1313 programmer, add these two items to the Favorites shortcut
so you can easily toggle between them:

Field Weakening Drive.
Set Max Speed to a very high speed that likely cannot be achieved by
the hydraulic system.
Set Field Weakening Drive = 100%.
Apply full throttle, and again work with just the rst stage if you have
a multistage mast. On each run, continue to lower the Field Weakening
Drive value and note the maximum speed (Monitor  Controller  Motor
Tuning  Motor RPM) the motor is able to achieve. Repeat and continue
lowering the Field Weakening Drive value until you notice the achievable
maximum motor speed fall o signicantly (20–30 rpm). is setting is
the Field Weakening Drive value you should set to achieve the maximum
torque / speed envelope of the motor. You can always reduce the Field
Weakening Drive value to improve energy consumption and eciency (but
reducing torque output) at high speeds.
Note: e Field Weakening Drive setting will have no eect at motor
speeds below FW Base Speed.
