8782 Master Encoder signal out of range

Description

Refer to Diagnostic class (standard): 3

A hardware encoder error is detected at the incremental encoder input (BT-4/ENC1, incremental encoder module INC-4), or incremental encoder module TM5SE1IC20005.

NOTE: Hardware encoder error. Reset the PacDrive controller. Only acknowledge the diagnostic message after reinitialization or homing.
 CAUTION
POSITION LOSS DUE TO SERCOS BUS ERROR
Only acknowledge the diagnostic message after reinitialization or homing.
Failure to follow these instructions can result in injury or equipment damage.

If necessary, use the function FC_SysReset() or FC_PrgResetAndStart().

Cause

Solution

Detected wiring error: Encoder cable at the encoder or the encoder input has been removed or is inoperable.

  • Verify the encoder cable and replace if necessary.

  • Verify and correct or replace if necessary the ground connection (shield).

The encoder/encoder supply or encoder simulation is not ready.

  • Disable the monitoring with the parameter CheckOff by standard.

  • If the encoder or encoder simulation is ready, activate the monitoring in the program.

Encoder inoperable.

Replace the encoder.

Additional possible cause by PacDrive LMC Eco:

Cause

Solution

The connected encoder does not match the configured encoder. (SinCos encoder connected, incremental encoder configured).

Adjust the configuration of the encoder or exchange the connected encoder.
