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 For instance, the setpoint speed limits are no longer active in the acceptance test mode.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
