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, or Z) 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.

The fault latch may be reset by pushing the Reset button, activating the
Reset input J1–12 or by removing power and allowing the filter
capacitor(s) to discharge. Note that the fault latch will not reset unless
the fault has been cleared.
Amplifier Failure
If the amplifier should fail, that is, if it should cease to operate with no
apparent fault, contact ANILAM.
