Expected result
6
Run the application (all the servo drives
are enabled).
–
Application runs as expected.
7
Enable STO.
Check that errors are generated correctly
when STO is activated while the servo
drives are running.
Motors are torque free. Motors coast and
stop after some time.
Statusword
bit 3 = 1, bit 14 = 1 and
object 0x603F shows fault 0xFF80 in all
servo drives.
8
Try to run the application (enable 1 or
more servo drives).
Checks that the STO function is working
correctly.
Application does not run.
9
Disable STO.
Check that the STO start is still inhibited
by the error signal.
Statusword
bit 3 = 1, bit 14 = 0 and
object 0x603F shows fault 0xFF80 in all
servo drives.
10
Try to run the application (enable 1 or
more servo drives).
Check whether reset is required.
Application does not run.
11
Send a reset signal via the PLC.
–
Statusword
bit 3 = 0 in all servo drives.
12
Try to run the application (all servo drives
are enabled).
–
Application runs as expected.
