CODE MEANING
37
Contactor closed
Cause: Relay remains closed when power to coil is disconnected.
Solution: Check relay.
38
Contactor Open
Cause: Inverter supplies power to relay coil but contact doesn’t close.
Solution: Check relay and power supply to coil.
49
I=0 Ever
Cause: Feedback current from motor sensor not constantly at 0.
Solution: Check connection to motor.
53
STBY I high
Cause: Internal fault detected in the inverter.
Solution: This is generally a temporary problem due to certain working condi‑
tions. If problem persists, replace inverter.
60
Capacitor Charge
Cause: Internal fault in the inverter.
Solution: Check connections and motor phases.
61
High temperature
Cause: High temperature inside the inverter.
Solution: Improve cooling to inverter. If fault persists, contact Jlg after‑sales servi‑
ce.
65
Motor temperat
Cause: High motor temperature.
Solution: Temporarily stop machine to allow motor to cool down.
67
Can Bus KO
Cause: Inverter doesn’t receive any information from Can Bus line.
Solution: Check connections using multifunction tester.
70
Encoder Error
Cause: Problem detected with encoder (=motor speed sensor).
Solution: Check speed sensor connection. Anomaly may also have been caused
by fault with bearing.
73
Thermis sensor KO
Cause: Signal from temperature sensor greater than 4.95 Volts or less than 0.1
Volt.
Solution: This is generally a temporary problem due to certain working condi‑
tions. If problem persists, replace inverter.
