Action and Reset
Action level
230V models: 410 VDC
460V models: 820 VDC
575V models: 1116 VDC
690V models: 1318 VDC
Action time
Immediately act when DC bus voltage is higher than the level
Reset method
Manually
Reset condition
Reset only when DC bus voltage is lower than 90% of over-voltage level
Recorded
Yes
Possible Causes
Corrective Action
• Power voltage is too high
• ON/OFF switch action of phase-in
capacitor in the same power system
• Incorrect wiring of brake resistor or
brake unit
• Malfunction caused by interference
• Hardware failure in voltage detection
• Motor ground fault
• Check if the input voltage is within the rated AC motor drive input voltage range, and check for
possible voltage spikes.
• If the phase-in capacitor or active power supply unit activates in the same power system, the input
voltage may surge abnormally in a short time. In this case, install an AC reactor.
• Check the wiring of brake resistor or brake unit.
• Verify the wiring of the control circuit and wiring/grounding of the main circuit to prevent interference.
• Check if other error code such as cd1–cd3 occur after cycling the power. If yes, return to the factory for
repair.
• The ground short circuit current charges the capacitor in the main circuit through the power. Check if
there is ground fault on the motor cable, wiring box and its internal terminals. Troubleshoot the
ground fault.

Pipe Leak Fault
Pipe leak detected in sleep mode where wake-up time is longer than
[ADV2-48]
,
[ADV2-49]
,
[ADV2-50]
, and
[ADV2-51]
.
Wake-up time is duration from pressure setpoint to wakeup level.
Action and Reset
Action level
Pressure drops for a duration longer than wake-up time between PID setpoint
[ADV2-52]
or and wakeup level.
Action time

Recorded
Yes
Possible Causes
Corrective Action
• Leak in pipe after pressure sensor
• System is low flow causing long delay
to reach wakeup level
• Pressurize pipe and then check for leaks
• Increase wake times
[ADV2-48]
through
[ADV2-51]
. Run system between different load demands and
record
Last Wake Time [ADV2-47]
for each run. Set wake times larger than recorded value.
