E8058

Drive system not ready for operation

Bosch Rexroth · IndraDrive C Drive Controllers

What does E8058 mean?

The drive system is not in a ready state to accept commands or operate the motor. This can be due to pending errors, incomplete initialization, or unfulfilled safety conditions.

Common Causes

  • One or more prerequisite conditions for operation (e.g., power-on, safety circuit closed, homing) are not met.
  • Internal errors or warnings within the drive controller preventing readiness.
  • Communication issues with the master controller (PLC) preventing the ready signal.
  • Incorrect drive configuration or parameter settings.
