4.3.1.3. Loss step test
This test makes it possible to check if a motor misses steps when performing a certain sequence of movements.
The test can be carried out with the speed and acceleration used in the normal functioning of the analyzer or
with these magnitudes increased by 10% to check the functioning safety margin.
4.3.1.4. Stress mode test
This test makes it possible for a certain sequence of movements to be performed continually. The technician
can program the duration of the test, which can be cancelled at any moment. Depending on the motor selected,
there is a minimum stress mode time (but in no case is it higher than 50 seconds).
4.3.1.5. Z axis secu ri ty systems test
The Z axis of the operating arm has an encoder to detect if there have been missed steps as a result of a co-
llision with the needle. In the case of a power failure, a mechanical system automatically raises the needle. On
selecting the corresponding options, the analyzer checks the functioning of each of these devices.
