ERROR CODE E1122 Unexpected motor power OFF.
Occurs when software turns motor power ON (K1 or K2 contactors ON) but there is no
signal feedback (MCON) indicating motor power is ON.
Main causes include:
1. Defect in the 1KP power sequence board.
2. Defect in the 1KQ/1NQ relay board.
3. Malfunction in the error detection circuit and error processing of 1KP/1KQ board.
4. Auxiliary contact of magnet contactor (K1, K2) for motor power is defective.
5. Malfunction with the servo software or the AS software.
6. Defect in the harnesses between 1KQ-CN3 and KI/K2.
⇒
Reinstall AS/servo software.
⇒
Replace the 1KP power sequence board.
⇒
Replace the 1KQ/1NQ relay board.
⇒
Replace the magnetic contactor (K1, K2).
⇒
Repair or replace the harnesses between 1KQ-CN3 and K1/K2.
⇒
Replace the MC unit.

ERROR CODE E1123 Speed error Jt XX.
Joint speed (motor speed) calculated using encoder values exceeds the rated value.
Main causes include:
1. Disconnected motor power line U, V, and/or W phase, or defective power block.
2. Wiring error in motor power line and/or encoder line.
3. Disconnected encoder signal line, short circuit in encoder or encoder wiring, and/or
defective main body of the encoder.
4. Robot motion program causes a singularity.
5. Defective 1KB servo board and/or power block.
6. Moment of inertia exceeded the motor torque.
⇒
Reduce payload to the specified ratings.
⇒
Check for disconnection, short circuit, and proper wiring for the U, V, and W motor
power line.
⇒
Replace the encoder and/or encoder harness as necessary.
⇒
Replace the 1KB board.
⇒
Replace the power block.
⇒
Rewrite program data such as speed and pose in the case of singularity motion.
