If there is no Alarm,
CN1-22
~
CN1-25
operates in accordance with default
function. Please refer to
2-2-1
.
Under-voltage
01
The main circuit
voltage is below its
minimum specified
value. (190Vac)
Use multi-meter to check
whether the input voltage is
within the specified limit. If it can
not be solved, there may be
failure inside the Drive.
Turn
ALRS(DI)
ON
1 1 1 0
Over-voltage
(Regeneration error)
02
1. The main circuit
voltage is exceeded
maximum allowable
value. (410V)
2. Regeneration
voltage is too high.
1. Use multi-meter to check
whether the input voltage is
within the specified limit.
2. Check the Parameter
Cn012
if
it is setting correctly.
3. If this alarm appears during
operation.
Extend ac/deceleration time
or reduce load ratio in the
permitted range. Otherwise,
an external regeneration
resistor is needed.
(Please contact your supplier
for assistance.)

Motor Over-load
03
The drive has
exceeded its rated
load during
continuous operation.
When the loading is
equal to 2 times of
rated loading, alarm
occurs within 10sec.
1. Check connection for Motor
terminal s (U,V,W) and
Encoder.
2. Adjust the Drive gain, If gain is
not correctly adjusted, it would
cause motor vibration and
large current will lead to motor
over load.
3. Extend acc/deceleration time
or reduce load ratio in the
permitted range.
Turn
ALRS(DI)
ON
1 1 0 0
Drive Over-current
04
Drive main circuit
Over current or
Transistor error.
1. Check connection of the motor
cable (U,V,W) and encoder.
Check power cable
connection. Refer to the
diagram in Chapter 2.
2. Turn off the power, and turn on
again after 30 min. If the alarm
still exists, there may be
power module malfunction or
noise consider the drive for
test and repair.
