Fault Name
Cause
Possible Solution
1.200 V class: 410 V
2.400 V class: 820 V
DC bus capacitor to
overcharge
4. Electrical signal
interference causes drive
malfunction
5. PG cable is
disconnected
6. Incorrect PG cable
wiring
7. PG encoder wiring is
interference by electrical
signal
relay terminals and motor
terminal box
3. Correct grounding shorts and
reapply power
4. Check the solutions for
interference suppression
»Check the control circuit lines,
main circuit lines and grounding
wiring.
»If the MC is the source of
interference, connect a
suppressor to it.
5. Reconnect the cable
6. Correct the wiring
7. Separate the wiring from the
source of the electrical signal
interference. It is usually the
output lines from the drive
Uv
Undervoltage
1.Voltage in the DC bus
fell below the
undervoltage detection
level (P2-03)
2.200 V class: 190 V
3.400 V class: 380 V
1. Input power phase loss
2. Loose wiring terminals
of drive input power
3. Problem with the
voltage from the drive
input power
4. The drive main circuit
capacitors are weakened.
5. The contactor or relay
on the soft-charge bypass
circuit is damaged
1. Correct the drive input power
wiring
2. Tighten the terminals
3. Check the voltage
a. Adjust the voltage according to
the drive input power
specifications
b. Check the main circuit
magnetic contactor if there is no
problem with the power supply
4&5. Turn on and turn off the
power to see if any problem
occurs
Replace either the entire drive or
the control board if the problem
continues to occur. Contact the
local distributor for more
information.

Undertorque Detection
1
The current has
dropped below the
1. Incorrect parameter
settings
2.Malfunction on
machinery side
1. Reset P6-01 and P6-02
2. Ensure there is no problem on
the machinery side.
