Tuning (F8)
NOTE:
ANILAM recommends that you set signal gain and balance the
servo amplifier, as discussed in previous text, before tuning.
CAUTION: Most machines will operate correctly with the default
filter parameters. Only qualified technicians who have
knowledge
of motion control tuning parameters should
use this tool.
The Tuning function can determine optimum values within constraints you
specify. The default values are usually correct for most machines. To
fine-tune, enter values manually or use this test. Refer to
Figure 11,
Tuning Parameters Test Results Screen
.
The Tuning Test has a setup screen that enables you to configure the
extent of the test. Check the setup parameters, run the test, and then
save the results. Refer to
Figure 10
and
Table 6
.

Parameter Function
Tune Ki
Switches integral tuning ON or OFF. [Default:
No
]
Tune Kd
Switches derivative tuning ON or OFF.
[Default:
No
]
Tune All Axis
If set, tunes all axes sequentially. [Default:
No
]
Match Axis
Lag
If set, calculates the inch/min/mil of each axis,
chooses the smallest one and matches the
inch/min/mil of the other axes to the smallest by
decreasing Kp.
Tune All Axis
must be set to use
this option. [Default:
No
]
Hunting
If linear scales are used, you can eliminate the back-
and-forth motion (hunting) produced by backlash.
[Default:
No
]
