ERROR CODE E1050 Encoder and brake power off signal not dedicated.
A gun change is executed on a servo spot weld gun without setting [Encoder and brake
power (7)] dedicated signal in AUX 0602.
⇒
From AUX 0602 Dedicated output Signals, set the [Encoder and brake power (7)]
signal to dedicated and enter the signal number.

ERROR CODE E1051 Incorrect double OX output.
When double type signals are used, if either output in the pair is turned ON, the other
turns OFF. An instruction to turn both outputs ON, or turn both outputs OFF (OX=1,2 or
OX=-1,-2), causes this error.
⇒
Change the OX signal setting.
⇒
Modify program data.

ERROR CODE E1052 Work sensing signal is not dedicated.
(sensing function)
This error occurs when the X-linear step is executed and the dedicated work sensing
signal is not detected. When the sensing function is used, a dedicated work sensing
signal must be set in AUX 1103.
⇒
Ensure the work sensing dedicated signal is set properly.

ERROR CODE E1053 Work sensing signal already input.
(sensing function)
Main causes include:
1. The X-linear step is executed and the work sensing signal is already on.
2. The sensing start-point is too close to the workpiece.
3. The sensing device or sensing device harness fails.
⇒
Reteach the start point further away from the workpiece.
⇒
Repair or replace sensing device or sensing device harness.
