Starting and performing the acceptance test
Subsequently, the acceptance test is to be explained using the "SS1" example.
1. Click on one of the functions being tested (SS1 in this case).
In the working area, the test tool is started.
2. Enter a test designation. This designation also appears later in the acceptance report.
3. As required, change the trace settings for this test or use the default settings. The
preassignment is adequate for most applications.
– In the "Recording Duration" field, enter the desired value for the recording duration.
– In the "Pre-trigger Duration" field, enter the desired value for the duration that is to be
A change enables adaptation to the mechanical conditions of the machine, e.g. if the
mechanical system of the axis has a very high moment of inertia, which would make longer
ramp times necessary for accelerating and braking.
4. Observe the safety information and notes on the start screen form of the acceptance test.
5. Once all precautions have been taken, click on the "Start" button in the "Start acceptance
wizard" area.
The assistant for the selected test is opened.
6. In the first step, traverse the drive so that Emergency Stop can be triggered.
In the "Move drive using" drop-down list, select whether the drive will traverse using the
control panel or using the user program of a higher-level controller.

– User program
7. Initiate emergency stop (SS1) on the selected drive. Click on "Next" once the LED displays
that SS1 is active.
The motor is braked along the AUS3 braking ramp. The transition to STO is made based on
the parameter assignment (e.g. after expiration of the delay time or when the shut-down
speed is undershot). If a brake parameterized via SBC is present, it is closed after transition
to STO.
8. Return the control priority when the drive is stationary. Click "Next".
9. The sequence carried out thus far is recorded and represented as a trace.
Based on the signal record, check the sequence of the test with respect to time and content.
In this test, STO must not be triggered until the motor is close to reaching a standstill. Click
"Next" once the test sequence matches your expectations.
10.If the sequence does not match your expectations, click "Cancel" to cancel the test.
In this case, check the correctness of all input conditions and repeat the test if necessary.
Example scenario: STO is initiated, even though the motor speed is still high. In this case,
faulty parameter assignment may be a possible cause, for example, a delay time for SS1 to
STO that is too short or a shutdown speed that is too high.
11.Deselect SS1 and click "Next".

recorded before the trigger.
If the drive traverses using the control panel, then the control panel is shown on this
screen. Activate the master control, specify a setpoint and start the motor in the desired
direction of rotation. Then click "Next" to go to the next step.
Start the traversing process if the drive is being moved using the user program. Once the
motor comes to a stop, click on "Next" for the next step.
