Introduction
This section describes how to use the ANILAM Motion Setup/Testing
(MST) Utility. The MST provides commands that carry out motion-specific
setup and testing in order to tune the servo system and the Proportional,
Integral, and Derivative (PID) filter parameters of a CNC.
A basic knowledge of machine operation and programming is required.
Refer to the 5000M CNC Programming and Operations Manual, P/N
70000508, for details on how to program and operate the control.
Setup includes the following procedures:
Servo Amplifier Balancing
Servo Amplifier Signal Gain Setting (motor step response is displayed
in open loop)
Instructions are provided for amplifier balancing and signal gain setting
when using the ANILAM AC Brushless Digital Servo Amplifiers and
motors. The servo amplifiers provided by ANILAM are completely digital;
parameter settings are done by communicating to the amplifier using the
Servo Amplifier Communications Cable, P/N 33001389, between the
amplifier's J1 connector and the CNC's RS-232 port. The digital amplifier
eliminates the need for adjusting trim pots and provides overall better
performance. Make sure cable is connected when doing any amplifier
adjustments; disconnect cable when done. If using amplifiers not
provided by ANILAM follow the manufacturer's guidelines for balancing,
signal gain setting, and overall adjustments.
The CNC provides the following troubleshooting tools:
Detection of Index Pulse
Detection of counts between index pulses (actual resolution)
Tuning for the optimal PID values
The following General Status information is displayed:
Display of active CNC status codes
Display of machine position, feedrates, RPM, dwell, and override

Detecting the Index Pulse (F3)
Refer to Figure 1, CNC Motion Setup/Testing Screen. When you press
IndexP (F3), the CNC displays a flashing “I” each time it detects an Index
Pulse. The flashing “I” replaces the axis name (X, Y, Z, U, W, or O) of the
active axis. The index pulse indicator (flashing “I”) for the spindle axis is
displayed on the RPM field. The figure shows the axis display when the
CNC has detected an index pulse in the (active) X-axis. Refer to
Figure 3.
To detect an index pulse:
1. Move the active axis to check for the presence of an index pulse.
2. On systems with rotary encoders with index pulses, the index pulse
should be detected once per revolution.
3. On systems having linear scales, the index pulse should be detected
where the linear scale specifies location of the index pulse.

Amplifier Faults
ANILAM amplifiers do not require any scheduled maintenance, although it
is a good idea to occasionally check for dust build up or other
contamination.
If an amplifier should cease to operate or one or more of the fault Light
Emitting Diodes (LEDs) are lit, refer to Table 4.
NOTE: A fault can on be caused by abnormal conditions. Locate and
correct the cause of the fault before repeated recycling of power
to the amplifier to prevent possible damage.
Table 4, Amplifier – LED Indicators
Red Green Condition
Off Off No power
Off On Enabled
On Off Fault
On On Inhibit
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 10,
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 9 and Table 5, Tuning Test Parameters.

Table 5, Tuning Test Parameters
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 (Imm) 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]
If you have selected Kd (derivative gain), the CNC begins by measuring
derivative sampling time (Ds). It measures the time between 10% and
90% of the final velocity (rise time) to determine the systems time
constant, from which the Ds travel is calculated.
WARNING: If you select the Kd test, you must have at least 2.5”
(63 mm) of travel in the positive (+) direction.
Next, the CNC calculates Kp (proportional gain). If the current overshoot
is smaller than the set one, Kp is increased by 1. If it is larger, Kp is
decreased by 0.1.
If you have selected Ki (integral gain), the CNC then calculates Ki and Il
(integral limit). If the lag between the commanded position and the actual
position is not zero, Il is increased by 5 and this portion of the test is
repeated.
The CNC calculates Kd, if selected. The CNC will attempt to decrease
the overshoot until the set value (Kd overshoot) is matched. When this
condition is not matched, Kd is increased by 2.
If you have chosen to test only one axis, the test is completed at this
point. If you have chosen to test multiple axes, and have not selected
“Lag Matching” the test will repeat the procedure on each axis in turn,
until complete.
If you have chosen all axes and Lag Matching, the CNC calculates the
inch/min/mil (Imm) of each axis being tested and matches the
inch/min/mil to the lowest value of all axes tuned.
