6.7 Commissioning: Basic procedure
● "Test sequence 1/test sequence 2"
You can set the following values for each brake to be tested brake and each required test
sequence:
– "Test torque"
– "Tolerance"
– "Test duration"
● LEDs "Test sequence active"
The LEDs "Test sequence active" display an AND logic operation from r10234.2,
r10234.3, and r10231.4. While r10234 indicates the status bits, r10231 represents the
control bits: As a consequence, r10231.4 only indicates as to whether test sequence 1 or
2 is selected, however not which one is currently active.
While a brake test sequence is active, switching bits 2 to 4 is ignored in r10231. However,
while test sequence 1 is active, by setting bit r10234.4 from 0 to 1, test sequence 2 can
essentially be preselected. However, even after setting bit r10234.4 to 1, test sequence 1
is first completed and test sequence 2 is not immediately selected. However, in
STARTER, as a result of this "preselection", the LED for the currently active test
sequence 1 is gray and the LED for the preselected test sequence 2 is green.

Set the test torque for the safe brake test as a factor in relation to the holding torque of
the brake. (p10210).
You can set the permissible positional deviation during the brake test (p10212) here.
You can set the duration of Safe Brake Test (p10211) here. During this time, the
selected test torque is active on the brake.
