16. Alarm display table

Status Display
0 READY Servo system is ready. The main power
cable and the encoder cable from the
servomotor are connected correctly.
1 OC An abnormally big instantaneous current
triggers the OC alarm. The Machine will
stop.
2 OV An abnormally high DC Bus voltage due
to too heavy load inertia or frequent
dynamic braking triggers the OV alarm.
The machine will stop.
3 OL An over 150% rated load lasting for one
minute triggers the OL alarm. The
machine will stop.
The temperature over 135°in the
4 OH
servomotor winding or over 85°in the
heat sink of the servo drive triggers the
OH alarm. The machine will stop.
5 OS An over 120% of the rated servomotor
speed triggers the OS alarm The Machine
will stop.
6 EE A broken encoder wiring or an incorrect
wiring of the UVW feedback signals
triggers the EE alarm. The machine will
stop.
7 LPF Internal power supply of logic block
failure.
8 RESET The servo drive control system is reset.
9 OVF An overflow of the position tracking error
triggers the OVF alarm. . The machine
will stop.

Solution
The servomotor can start a normal
operation
Check whether the load exceeds the
rated value, any main circuit
component is damaged, or output is
short-circuited.
Check whether the load inertia is over
the specification and take into
consideration an extra regenerative
braking resistor.
Check the reason of overload.
Check the ambient temperature and
the ventilation condition.
Check whether the speed command
exceeds the allowable value or the
load is over the specification.
Refer to the wiring diagram and
check the wiring again.
Send back to repair.
The system will start again after the
alarm is cleared.
Check whether the load is over the
specification or the frequency of
position pulse command is too high.
