Overvoltage
Voltage in the DC
bus exceeded the
overvoltage
detection level
1.200 V class: 410
V
2.400 V class: 820
V( 740 V when d1-
01＜400 )
1. Drive input
power has surge
voltage entering
2. Machinery
output short circuit
3. Ground fault in
the output circuit
causes the DC bus
capacitor to
overcharge
4. Electrical signal
interference causes
drive malfunction
1. Install a DC link choke
Voltage surge can result
from a thyristor
convertor and phase
advancing capacitor
using the same input
power supply
2. Check the motor
power cable, 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
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
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
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
