OPEN DRIVE
In the first step is checked if the cyclic sense of motor phases and Endat sensor is the same:
after 1 second parameter P79 is updated with the test result and the drive consequently goes in alarm A14 or
it starts the second test:
o
o
P79<0 : meaning that motor phases have opposite cyclic sense of Endat sensor.
P79>0 : everything is ok
In the second part is checked the sensor reading, well known that current test frequency is 0,5Hz the time
needed for read again the same position is equal to:
time test = 2 ⋅ Motor polar couple number [seconds]
At the end of the test, P79 is updated again with the time test measured in ms:
o
|P79- time test| < 500ms : test is successful
otherwise the alarm A15 code d49=3 is triggered. In the first check if it is correct the number of
motor poles, with help of P79.
The test is successful if the drive switch off and does not trigger an alarm. Now disable RUN command by
setting its digital input to 0. The subsequent tests can now be carried out.
