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 4200T CNC Programming and Operations Manual,
P/N 70000412, 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)
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
Accessing the MST Utility
Access the Motion Setup/Testing Utility (MST) from the Software Options
Screen. This screen activates automatically once the CNC has started
successfully.
To activate the MST Utility:
1. Start the CNC.
2. Press (F10) to continue, as prompted. The Software Options screen
is displayed.
3. Highlight Motion Setup/Testing, and press ENTER. The MST screen
activates.

MST Soft Keys
NOTE: Select an active axis before you select an MST command
(F1–F10).
NOTE: MST soft keys are displayed while the MST screen is active.
Access MST utility features using the labeled soft keys located below the
screen on the console. Press the corresponding soft key (F1–F10) to
activate the function.
Refer to Table 2 for soft key names and functions.
Table 2, MST Soft Key Functions
Soft Key Name Function
F1 ClrFld
Clears prompt field in SigGain and Tuning tests.
F2 ResChk Calculates the resolution of the active axis.
Troubleshooting tool.
F3 IndexP
Detects Index Pulse and displays an indicator over
the Active Axis line of the MST screen.
Troubleshooting tool.
F4 Manual Cancels active MDI or test command.
F5 MDI Activates an MDI prompt.
F6 Balance Sends out the signal needed to Balance the outputs
of the system (0.0 VDC). Used to balance the
Motion Control Board and the Servo Amplifiers.
F7 SigGain Allows you to set the servo amplifier signal gain for
the active axis.
F8 Tuning Activates the Tuning Pop-Up menu, which allows the
CNC to determine optimum PID filter values from the
specified parameters and save the results.
F9 Misc Miscellaneous tests displays a pop-up menu with
options for CanBus Test. For AC motors only
additional options display on the pop-up menu:
Amplifier Test Link, Reset Amplifier, Backup Amp
Settings, and Restore from Backup. These tests can
only be activated with the Servo Amplifier Test Board
installed. See for DC systems “Servo Drive Test
Board” or for AC systems “Servo Amplifier Test
Board.”
F10 Exit Returns the CNC to the Software Options screen.
(SHIFT+F4) Home Performs a Homing Sequence on all axes configured
for homing.

Clearing a Prompt Field or Message (F1)
Press ClrFld (F1) to clear an erroneous entry. This soft key is available
during the Signal Gain and Tuning tests.
Selecting an Axis
NOTE: Select an active axis before you select an MST command
(F1–F10). If you do not select an axis, the CNC displays an
Error message that prompts you to select an axis.
Use the following keypad keys to select and activate the corresponding
axes:
XActivates/Deactivates X-axis
ZActivates/Deactivates Z-axis
Sor SActivates/Deactivates Spindle Axis

The CNC displays the active axis in the upper-left corner of the General
Status area of the MST Screen.
Entering a Password
When you enter the MST Utility and press Balance (F6), SigGain (F7), or
Tuning (F8), the CNC prompts for the password. Type the appropriate
password and press ENTER. Refer to 4200T CNC Setup Utility Manual,
P/N 70000414, “Section 1, Password Restricted Parameters.”
The soft key activates. If you have entered the password successfully,
the CNC will not prompt for the password again, unless you exit and
re-enter the MST Utility.

Checking Axis Resolution (F2)
Refer to Figure 2. Press ResChk (F2) to calculate the actual resolution
for the active axis. In the Graphic Area of the screen, the actual
resolution and the resolution in the Setup are displayed for comparison.
In addition, the screen displays:
•The number of times the system tested for resolution (Total Cycles:)
•The number of times the encoder lines detected do not match the
number of encoder lines in the setup (Errors:). An error indicates that
something is wrong, either in the setup parameters or in the hardware.
•The actual number of encoder lines found by the test (Encoder Lines:)
•The resolution and counts per revolution found. (Encoder
Resolution:)
NOTE: Resolution should be four times the number of encoder lines.
Once this test is activated, you must move the axis for at least two
encoder revolutions via MDI Mode, Jog Mode, or manual move. The
CNC performs the calculation continuously until motion stops.
NOTE: This test is not available for axes with linear encoders.
NOTE: Do not perform this test during Rapid Mode. Use it in Feed
Mode only.

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, Z, or S) 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.
