What to do
Check motor ratings and load.
Let motor cool down. Ensure proper
motor cooling: Check cooling fan, clean
cooling surfaces, etc.
Check value of alarm limit.
Check motor thermal model settings
(parameters 31.09...31.14).
Check that actual number of sensors
corresponds to value set by parameter
31.02 Mot temp1 src.
Check motor ratings and load.
Let motor cool down. Ensure proper
motor cooling: Check cooling fan, clean
cooling surfaces, etc.
Check value of alarm limit.
To restart drive, activate Run enable
signal (source selected by parameter
10.11 Run enable) and start drive.
Check setting of parameter
enable. Switch signal on (e.g. in the
fieldbus Control Word) or check wiring of
selected source.
This alarm belongs to normal start-up
procedure. Wait until drive indicates that
motor identification is completed.
procedure.
Select how motor identification should be
performed, parameter 99.13 Idrun
Start identification routines by pressing
Start key.
Check that it is safe to continue
operation.
Return emergency stop push button to
normal position (or adjust the fieldbus
Control Word accordingly).
Restart drive.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameters
48.01...48.05).
Check alarm limit setting, parameter
48.07 Br temp alarmlim.
Check that braking cycle meets allowed
limits.
Let chopper cool down.
Check resistor overload protection
function settings (parameters
48.01...48.05).
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
