Cause
Troubleshooting
Solution
1. The three‑phase input
cables are connected
improperly.
Check whether RST cables
on the drive side and non‑
drive side are in good
condition and connected
properly.
Replace the cables and
connect the main circuit
cables properly.
2. A single‑phase power
supply is used for a three‑
phase servo drive.
Check the specifications of
the power supply and
measure whether the
voltage input to the main
circuit is within the following
range:
220 V servo drive:
Value range: 220 V to 240 V
Allowable deviation: –10%
to +10% (198 V to 264 V)
380V servo drive:
Effective value: 380 to 440 V
Allowable deviation: –10%
to +10% (342V to 484V)
Measure the voltages of all
the three phases.
Servo drives of 0.75 kW
(H01.10 = 5) can be supplied
by single‑phase power
supplies.
If the input voltage complies
with the specifications, set
H0A.00 (Power input phase
loss protection) to 2 (Inhibit
phase loss faults and
warnings).
If input voltage is outside
the specified range, replace
or adjust the power supply.
3. The three‑phase power
supply is unbalanced or the
voltages of the three phases
are too low.
● E420.1: Main circuit PL signal detection error
Cause
Troubleshooting
Solution
1. The three‑phase input
cables are connected
improperly.
Check whether RST cables
on the drive side and non‑
drive side are in good
condition and connected
properly.
Power off and on the servo
drive again. If unexpected
power failure occurs, ensure
the power supply is stable.
2. A single‑phase power
supply is used for a three‑
phase servo drive.
Check the specifications of
the power supply and
measure whether the
voltage input to the main
circuit is within the following
range:
220 V servo drive:
Value range: 220 V to 240 V
Allowable deviation: –10%
to +10% (198 V to 264 V)
380V servo drive:
Effective value: 380 to 440 V
Allowable deviation: –10%
to +10% (342V to 484V)
Measure the voltages of all
the three phases.
Replace or adjust the power
supply according to the
range.
3. The three‑phase power
supply is unbalanced or the
voltages of the three phases
are too low.
