1 M.NOT RUNNING (Motor does not run)
Display Description
The protective function is activated
M.NOT RUNNING
to bring the inverter to an alarm
ALARM
stop.
Indicated
Press the SHIFT-key to display the
<SHIFT>
cause of the trip.
The inverter's main circuit power is
M.NOT RUNNING
lost or there is an open phase in the

power supply.
or Phase Loss
Check the power supply.
Both start signals STF and STR are

ON or OFF.
STF, STR
both are OFF
or ON
MRS signal is ON.
M.NOT RUNNING
MRS is ON
The inverter starting frequency (Pr.

quency currently set.
Pr. 13
The current input select signal AU
M.NOT RUNNING
remains OFF. (not ON)
AU is OFF
Display Description
The inverter cannot start because the inverter starting
M.NOT RUNNING
frequency (Pr. 13 ) is higher than the maximum fre-
