Malfunction Detection
LV
If the normal control input voltage of 48 V
drops to 36 V or less due to the load, a red
LED (LV-HV) in the alarm display panel
lights up while the buzzer sounds to warn
that the battery remaining charge is
insufficient.
Immediately recharge the battery.
If the load is removed and the voltage is
restored, the buzzer stops.
The voltage drop due to the load increases
if the battery remaining charge has become
insufficient.
A malfunction is detected if the warning
continues for 30 seconds or more and, in
addition to the red LED (LV-HV) lighting up
and the buzzer sounding, the travel safety
device automatically applies the brake
since the machine enters a free-run state.

OL
If a load greater than rated one is applied to
the motor, the red LED (OH-OL) in the
alarm display panel lights up and the
buzzer sounds to warn that the load applied
to the motor is too large.
Travel at low speed.
If the load is reduced to no more than rated
one, the buzzer stops.
If the warning continues for 30 seconds or
more and a malfunction is detected, in
addition to the red LED (OH-OL) lighting up
and the buzzer sounding, the travel safety
device automatically applies the brake
since the machine enters a free-run state.
Load greater than rated one applied to the motor
↓
Red LED (OH-OL) lights up while buzzer sounds
to warn of overload
↓
OL (overload) occurs if warning continues for 30
seconds or more
↓
Travel control stops (machine enters free-run
state)
Malfunction detected and warning indicated with
red LED (OH-OL) lighting up while buzzer sounds
