49
I=0 Ever
Cause: Feedback current from motor’s sensor not constantly kept at 0
Solution: Control the connection with the motor
53
STBY I high
Cause: Fault detected in the inverter
Solution: Usually it is a temporary anomaly due to a particular working condition. In case
the anomaly persists replace the inverter.
60
Capacitor Charge
Cause: Problem in the inverter
Solution: Control the connections and the motor phases
61
High temperature
Cause: Temperature rise in the inverter.
Solution: Allow a better cooling to the inverter. If the anomaly persists contact JLG after
sales dept.
65
Motor temper at
Cause: High motor temperature
Solution: Stop the machine temporarily to enable motor cooling
67
Can Bus KO
Cause: The inverter does not receive any information from Can Bus line
Solution: Control the connections with the multi function tool
70
Encoder Error
Cause: Anomaly detected on encoder (= engine rpm sensor)
Solution: Control the rpm sensor connection. The anomaly may also be caused by a bear-
ing fault.
73
Therm is sensor KO
Cause: The signal from the temperature sensor is higher than 4,95 Volt or lower than 0,1
Volt
Solution: Usually it is a temporary anomaly due to a particular working condition. In case
the anomaly persists replace the inverter.
74
Driver shorted
Cause: Anomaly to the relay supply.
Solution: Control relay supply. Usually it is a temporary anomaly due to a particular work-
ing condition. In case the anomaly persists replace the inverter.
75
Driver shorted
Cause: Anomaly to the relay supply.
Solution: Control relay supply. Usually it is a temporary anomaly due to a particular work-
ing condition. In case the anomaly persists replace the inverter.
76
Coil shorted
Cause: Anomaly detected in the relay coil
Solution: Control the integrity of relay support.
