9-4 Tuning
●
Distance sets the rotation limit of the motor. This is the maximum
distance the motor is allowed to move during any one test.
●
Step Current sets the amount of current given to the motor during
the test. If this is set too low, a system may not move enough to
gather sufficient data, if it is set too high the test will be too short
and very jerky.
●
Motor Direction (Forward Only/Reverse Only/Bi-directional) sets
the rotational direction for the test. The bi-directional test does the
same test in both directions, with the forward rotation first.
Auto tune procedures are explained for each drive configuration in
“Application and Configuration Examples” starting on page 8-1. The
following steps generalize the ULTRA Master tuning procedures.
Similar procedures apply for the TouchPad.
When autotuning is selected, the drive rotates the motor shaft for a
short time interval, typically a few seconds. Motor movement should
not exceed 30 seconds.
1. Choose the T uning command icon from the Drive window.
2. Choose A uto Tune from the Tuning window. This activates the
Auto Tune Command and Motor Direction boxes within the Tun-
ing window. Then enter or select:
• appropriate values for Distan c e in the Auto Tune Command
box,
• appropriate values for S t ep Current in the Auto Tune Com-
mand box, and
• an appropriate motor rotation in the Motor Direction box on a
PC, either:
– B iDirectional , if the motor will be powered in both the
forward and reverse directions.
– For w ard Only , if the machinery is designed to operate only
in the forward direction.
– R e verse Only , if the motor will be powered only in the
reverse direction.
Note: Autotuning in the bi-directional mode includes two different
tests.

ATTENTION: Rotating motor shafts can cause extensive
damage and injury. Motors must be properly guarded dur-
ing testing and installation.
