PROGRAMMED DIAGNOSTICS FOR SE-4P
Some simple diagnostic tests are available in the program, by using the Hand Held Terminal. These
require using the “Shift” key on the keypad: refer to the keypad character map for shifted characters, to
use these commands.
If the machine is a DUAL FUNCTION SE4-PD or SE-4PTD, change function to the PIPE PROGRAM to
perform the following tests.
Press “T” for Test
The display should show “D-E-F?”
Next press D to check Drives
E for Encoders
F to Finish; get back to main menu
After selecting either D or E, for Drive or Encoder, the display will show “Axis No.”
Press 1 for Axis 1: rotation, or 2 for Axis 2: longitudinal motion.
If Drive was selected, the corresponding axis selected should run
1 second forward (display will show ‘F’)
1 second back (display will show ‘B’)
The drive should move at the speed set by the speed pot, regardless of whether encoder pulses are
being counted.
If Encoder was selected, the encoder count of the corresponding encoder (1 or 2) should
scroll up continuously in the display. Press any key to stop. Rotating the encoder in either
direction will increase or decrease the displayed count, if the computer is successfully
counting the pulses from it. The encoder can be rotated manually if disengaged, or by using
the joystick to move in the desired direction.
Note: the count is in hexadecimal notation (number base 16), (10 H=16 decimal, 400 H =
1024 decimal).
1 rotation of the encoder corresponds to 400 (HEX) counts.
Program Version:
Press “V” to determine the Version. No.; e.g. SEO41, which will show on the display.
