undervoltage fault
Causes
1. CPU loading ratio is too high
2.DSP software fault
Two or more digital inputs are
configured to the same functions
If the drive is standard, the analog
input 3 is speed command
The pulse input frequency
detected by the drive is higher
than the designated value
1. External input pulse signal
frequency is too high.
2. Damage of internal drive pulse
frequency detection circuit
The DC voltage of the main circuit
is higher than the designated
value
1. The grid voltage is too high;
2. No braking resistor or pipe
during braking or the braking
resistor is damaged;
3.DEC time is too short during the
stopping;
4. The internal DC voltage test
circuit is damaged
The DC voltage of the main circuit
is less than the designated value
1. The grid voltage is too low;
2.The buffer relay is not switched
on;
3. The drive output power is too
large;
4. The internal DC voltage test
circuit is damaged
The DC voltage of the control
power is less than the designated

Faults and solutions
Countermeasures
1. Reduce the software function;
2. Contact the customers service
and change the DSP software.
Reset P3.00~P3.09 and ensure
there is no repeated setting.
Set P3.70 to other value.
1. Reduce the external input pulse
signal frequency;
2. Change the drive if fault occur
when external input signal is normal.
1. Check whether the grid input
voltage exceeds the allowed value;
2. Check whether the internal
braking resistor is loose or damaged;
check whether external braking
resistor is damaged;
3.Enlarge the setting value of
ACC/DEC time;
4. Monitor R0.07 when the drive is
disabled, if it is abnormal and does
not match with grid input voltage,
change the drive.
1. Check whether the grid input
voltage is lower than the allowed
value;
2. Repower on, and check whether
there is pull-in noise of the relay;
3. Monitor R0.07 when the drive is
disabled, if it is abnormal and does
not match with grid input voltage,
change the drive.
1. Check whether the grid input
voltage is lower than the allowed
