Encoder Read Test
Use this test to verify that the controller receives the correct feedback from
the pre-aligner. Before you move an axis as requested, make sure the pre-
aligner signal cable is securely connected.
As you manually move each axis, observe whether the encoder number
counts up or down:
• As the t axis moves in the positive (clockwise) direction, the number
should count up and as it moves in a negative direction, the number
should count down smoothly.
• As the r axis moves in the positive (counter-clockwise) direction, the
number should count up and as it moves in a negative direction, the
number should count down smoothly.
• As the z axis moves up, the number should count up and as the z axis
moves down, the number should count down.
If this test fails for an axis, replace the signal cable. If the test continues to
fail, contact Equipe Customer Support for further instructions.
Limit & Home Test
Before you move the axes to activate the switch indicators, make sure the
pre-aligner signal cable is securely connected.
In the display, the square brackets indicate the characters inside might not
appear on the screen. The symbols [–], [H], and [+] respectively indicate
that the negative limit switch, home switch, and positive limit switch are
activated.
When you move the axes to their limits (negative or positive), the display
changes to indicate activation of the limit switches. Activating the
negative limit switch on an axis triggers the Home switch for that axis.
