What is meant by "acceptance test mode"?
The acceptance test mode can be activated for a definable period (p9358/p9558) by setting
the appropriate parameters (p9370/p9570). It tolerates deliberate 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 For instance, the setpoint speed limits are no longer active in the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 p9358/p9558.
It only makes sense to activate the acceptance test mode during the acceptance test of the
SS2, SOS, SDI and SLS 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 the acceptance test mode active (also 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 move. When an SOS violation is acknowledged in the active
acceptance test mode, the actual position is adopted as the new stop position so that an
SOS violation is not immediately identified again.
Danger due to unintentional axis movements
For the following settings , the axis starts to move as soon as the acceptance test is
activated:
• Speed setpoint not equal to zero
• Active stop function (SS2)
• The motor is at a standstill (active SOS)
Before you start the acceptance test, check as to whether functions that could possibly
cause axes to move are still active.
