Timeouts and other errors
Process timeouts
Parameter P2014 defines the permissible timeout in ms. Value zero prevents timeout
monitoring. Parameter P2014 checks the cyclic update of bit 10 in control word 1.
If the USS is configured as a command source for the drive and P2014 is not zero, bit 10 of
the received control word 1 is checked. If the bit is not set, an internal timeout counter is
incremented. If the threshold defined in P2014 is reached, the drive sets a process timeout
error.
