EF5
External fault (input terminal S5)
External fault at multi-function input terminal S5.
EF6
External fault (input terminal S6)
External fault at multi-function input terminal S6.
EF7
External fault (input terminal S7)
External fault at multi-function input terminal S7.
EF8
External fault (input terminal S8)

FbH
Excessive PID Feedback
The PID feedback input is higher than the level set to b5-36 for longer than the time set to b5-37, and b5-12
is set to 1 or 4.
FbL
PID Feedback Loss
The PID feedback input is lower than the level set to b5-13 for longer than the time set to b5-14.
Hbb
Safe Disable Signal Input <1>
Both Safe Disable Input channels are open.
<1> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN 61800-5-1, ISO/EN
13849 Cat. 3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
HbbF
Safe Disable Signal Input <1>
One Safe Disable channel is open while the other channel is closed.
<1> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN 61800-5-1, ISO/EN
13849 Cat. 3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
HCA
Current Alarm
Drive current exceeded overcurrent warning level (150% of the rated current).
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.
oH
Heatsink Overheat
The temperature of the heatsink exceeded the overheat pre-alarm level set to L8-02 (90-100 °C). Default
value for L8-02 is determined by drive capacity (o2-04).
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).
