Have a critical attitude towards values
shown on counters.
Reset the fault and restart.
Should the fault re-occur, contact your
local distributor.
Cancel prevention of start-up if this can
be done safely.
Check motor cooling and loading
Check thermistor connection
(If thermistor input of the option board is
not in use it has to be short circuited)
Check loading.
Check motor size.
Contact your local distributor.
Ensure that there is another device on
the bus with the same configuration.
Contact your distributor. If you are
