Commissioning

Replacing software/hardware

After hardware and/or software components have been changed or replaced, it is only

permissible to boot the system and activate the drives when the protective devices are closed.

It is not permissible that personnel are present within the danger zone.

It may be necessary to carry-out a new, partial or complete acceptance test depending on

the requirement or replacement.

Before persons may re-enter the hazardous area, the drives should be tested to ensure that

they exhibit stable behavior by briefly moving them in both the plus and minus directions (+/–).

This is especially important specifically for high-speed linear or torque motors.

The function "safe software limit switch" (SE) is also called "safe limit positions" and the

function "safe software cams" (SN) is also called "Safe Cams".

Activating SI functions

If SI functions SH, SBH or SG have been enabled, then they become operational after the

control system has booted (basic display on screen). For the SE and SN functions, safety-

related position evaluation is only possible after safety-related referencing has been

successfully completed.

Protection of persons

Protection of operating personnel must be the primary consideration when configuring

machine data for SINUMERIK Safety Integrated. This is this reason that the parameterizable

tolerances, limit values and delay times should be determined and optimized during the

commissioning phase dependent on the machine design and arrangement.
