Fault Name Display Possible Cause Action
IGBT
overtemperature
E14.00 High ambient temperature Lower the ambient temperature.
Blocked air filter Clean the air filter.
Damaged fan Replace the damaged fan.
Damaged thermistor of the IGBT Contact the agent or Inovance for technical
support.
Damaged IGBT Contact the agent or Inovance for technical
support.
External fault E15.01 External fault signal input to the
multi‑function DI terminal
(normally open)
Rectify the external fault, and ensure that the
mechanical condition allows restart (F8‑18).
E15.02 External fault signal input to the
multi‑function DI terminal
(normally closed)
Rectify the external fault, and ensure that the
mechanical condition allows restart (F8‑18).
Communication
fault
E16.01 Modbus communication timeout Ensure proper wiring of the RS485
communication cable.
Ensure proper settings of FD‑04 and PLC
communication cycle.
E16.11 CANopen communication
timeout
Ensure proper connection of the CAN
communication cable.
Check the values of FD‑15 to FD‑17 and eliminate
interference.
E16.12 Inconsistency between the
configured CANopen‑based PDO
mapping and the actual mapping
Check the PDO mapping of parameters in group
AF.
E16.21 CANlink heartbeat timeout Ensure proper connection of the CAN
communication cable.
Check the values of FD‑15 to FD‑17 and eliminate
interference.
E16.22 CANlink station number conflict Change the value of FD‑13 to make CANlink
station numbers different from each other.
Contactor fault E17.00 Abnormal driver board and
power supply
Replace the driver board or power supply board.
Abnormal contactor Replace the contactor.
Abnormal lightning protection
board
Replace the lightning protection board.
Damaged current
sampling circuit
E18.00 Abnormal AC drive current
sampling
Power on the main circuit.
If the Hall sensor or sampling current circuit is
damaged, contact Inovance.
