ERROR CODE E1034 Encoder initialize error (Jt XX).
The encoder is not able to read the absolute position at control power on. The scanning
of absolute data begins immediately after a shift from the state of non-operation, or
back-up operation, to normal encoder operation. BUSY=1 is output until the absolute
position has been determined.

Main causes include:
1. Encoder rotated at 300 RPM or more at controller power-up (including conveyor
encoder).
2. Defective encoder or encoder harness.
3. Defective 1KB, 1KQ/1NR, or 1GF/1HG board.
4. Defective manual brake release.
In the case of a conveyor encoder, ensure power-up speed is below 300 RPM.
Check connections at encoder, 1FG/1HG board.
Ensure the 1KB board is properly seated into the card rack.
Replace encoder, replace 1KB, 1KQ/1NR, or 1FG/1HG board.
Check for continuity in the machine harness, separation and signal harness repair or
replace as necessary.
For additional information on error code E1034, see section 1.4.
