HOA Keypad Display Alarm Name
Low Water in Tank Low Water in Tank
Low WL/SP/PI-Aux Drive Disabled
Low Water Level / Suction Pressure / Aux PI Feedback Disabled
Water Level or Suction Pressure is below the Q4-06/Q5-06/Q6-06 setting.
LT-1
Cooling Fan Maintenance Time
The cooling fan has reached its expected maintenance period and may need to be replaced.
Note:
An alarm output (H2-oo = 10) will only be triggered if both (H2-oo = 2F and H2-oo = 10) are
set.
LT-2
Capacitor Maintenance Time
The main circuit and control circuit capacitors are nearing the end of their expected performance life.
Note:
An alarm output (H2-oo = 10) will only be triggered if H2-oo = 2F.
LT-3
Soft Charge Bypass Relay Maintenance Time
The DC bus soft charge relay is nearing the end of its expected performance life.
Note:
An alarm output (H2-oo = 10) will only be triggered if H2-oo = 2F.
LT-4
IGBT Maintenance Time (50%)
IGBTs have reached 50% of their expected performance life.
Note:
An alarm output (H2-oo = 10) will only be triggered if H2-oo = 2F.

NETSCAN
Drive is waiting for a message from the master.
NMS
Not Maintaining Setpoint
The setpoint cannot be maintained and P1-17 is set to 1.
oH
Heatsink Overheat
The temperature of the heatsink exceeded the overheat pre-alarm level set to L8-02.
oH2
Drive Overheat Warning
“Drive Overheat Warning” was input to a multi-function input terminal, S1 through S8 (H1-oo= B).
oH3
Motor Overheat
The motor overheat signal entered to a multi-function analog input terminal exceeded the alarm level (H3-02, H3-06
or H3-10 = E).
oH5
<1>
Motor Overheat (NTC Input)
The motor temperature exceeded the level set to L1-16 (or L1-18 for motor 2)
oL1
Motor Overload
The electronic motor overload protection tripped
oL2
Drive Overload
The thermal sensor of the drive triggered overload protection.
oL3
Overtorque Detection 1
The current has exceeded the value set for torque detection (L6-02) for longer than the allowable time (L6-03).
oL4
Overtorque Detection 2
The current has exceeded the value set for Overtorque Detection 2 (L6-05) for longer than the allowable time
(L6-06).
ov
DC Bus Overvoltage
The DC bus voltage exceeded the trip point.
• For 200 V class drives: approximately 410 V
• For 400 V class drives: approximately 820 V (740 V when E1-01 is less than 400)
• For 600 V class drives: approximately 1040 V
