Flow Chart 0-9 E1022 Error Code
E102
HOMING SEQUENCE FAILED
This error only occurs while the tyer is in its homing sequence. It indicates the homing sequence took
too long. One or more of the Servo Motors were unable to complete their HOMING sequence.
SAFETY WARNING:
The following troubleshooting procedure may require that tests be made with the electrical
enclosures open and power turned “ON”. These tests should only be conducted by authorized
personnel who are aware of the electrical and mechanical hazards present.
Clear jam.
The most likely reason for this error is a mechanical obstruction or jam
which is preventing a motor from moving as needed. With power turned
“OFF”, turn each motor thru its complete range of motion, (MTR1) <
360°, (MTR2-4) ≥ 360° check for debris, is a jam present?
Attempt another homing sequence while viewing motors (MTR1-3) and verify
which motor is not moving, also E102 is often followed by another E-code
which can assist in determining which motor is experiencing problems.
