Encoder initialization error. Axis XX. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Not possible.

Description: Absolute position data cannot be determined if the encoder is rotating at 250rpm or more when the controller power is turned ON. This error then occurs. (Corresponds to the encoder BUSY bit.)

Main causes:

1. The motor (encoder) is rotating at 250rpm or more when the controller power is turned ON. (This also applies to conveyor encoders and similar devices.)

2. A problem with the encoder.

Countermeasures:

1. Keep the motor (encoder) rotation speed below 250rpm when the controller power is turned ON.

2. Replace the encoder.
