1.4 Start-up and Operation
Risk of serious injury or death!
Unintentional drive behavior during initial start-up or replacement of the
drive controller!
ï‚„ Wrong parameterization can cause unintentional behavior of the drive.
ï‚„ Secure motors against automatic restart.
ï‚„ Check whether the appropriate parameter list for the application has been
imported.
Risk of serious injury or death!
Protection function in case of software problems without function!
ï‚„ Securing a unit solely with software-supported functions is not sufficient.
ï‚„ Install external protective measures (e.g. limit switch) that are
independent of the drive controller.
