Remedy
Check installation and field-
bus master.
Check board and slot
Check motor cooling and
load.
Check thermistor connection
(If thermistor input is not in

cuited)
Carry out the needed mainte-
nance and reset counter.
Check parameters in Field-
bus Data Mapping menu
(chapter 3.5.8).
The value being mapped may
be of undefined type. Check
