Hardware Fault of Active Encoder

XYZ CT52 Lathe with Siemens 828DSL & Sinamics drives. A hardware fault of the active encoder on the Z-axis alarm was identified.

We quickly diagnosed the problem and a new encoder was sourced and fitted. Don't try this at home! It was very complicated to align the encoder commutational angle and centralise it to prevent any following errors.

We managed to complete this without removing the motor from the customer's machine. The Z-axis reference position was resent, a new NC archive was made and the machine was making swarf agan in no time.
