Necessity of an acceptance test
A complete acceptance test (as described in this chapter) is required after initial commissioning
of Safety Integrated functionality on a machine. The acceptance tests must be carried out for
each individual drive. Safety-related function expansions, transfer of the commissioning
settings to other series machines, hardware changes, software upgrades or similar, permit the
acceptance test to be performed with a reduced scope if necessary. A summary of conditions
which determine the necessary test scope or proposals in this context is provided below.
Requirements for the acceptance test
● The machine is properly wired.
● All safety equipment such as protective door monitoring devices, light barriers or emergency
limit switches are connected and ready for operation.
● Commissioning of the open-loop and closed-loop control must be completed, as e.g. the
over-travel distance may otherwise change as a result of a changed dynamic response of
the drive control. These include, for example:
– Configuration of the setpoint channel
– Position control in the higher-level controller
– Drive control
Note on the acceptance test mode
The acceptance test mode can be activated for a definable period (p9558) by setting the
appropriate parameters (p9570). It tolerates specific limit violations during the acceptance test.
For instance, the setpoint speed limits are no longer active in the acceptance test mode. To
ensure that this state is not accidentally kept, the acceptance test mode is automatically exited
after the time set in p9558.
It is only worth activating acceptance test mode during the acceptance test of the SS2, SOS,
SDI, SLS and SLP functions. It has no effect on other functions.
Normally, SOS can be selected directly or via SS2. To be able to trigger violation of the SOS
standstill limits with acceptance test mode active (even in the "SS2 active" state), the setpoint
is enabled again by the acceptance test mode after deceleration and transition to SOS to allow
the motor to travel. When an SOS violation is acknowledged in the active acceptance test
mode, the current position is adopted as the new stop position so that an SOS violation is not
immediately identified again.
Axis movement during the acceptance test
If a speed setpoint ≠ 0 is present, the active stop function SS2 is set, and the motor is at a
standstill (active SOS), the axis starts to move as soon as the acceptance test is activated. If
persons are in the danger zone, accidents causing death or severe injury can occur.
● Take suitable measures to ensure that nobody is in the danger zone during the acceptance
