Name Possible Causes Solution Level
Err14 Module overheat
The ambient temperature is
too high.
◆
Lower the ambient temperature.
5A
The fan is damaged.
◆
Replace the fan.
◆
◆
Check whether the installation clearance of
Err15
Output
abnormal
Subcode 1: The regen. resistor
is short circuited.
◆
Check wiring of the regen. resistor and brak-
ing unit is correct, without short-circuit.
◆
Check whether the main contactor works
properly and whether there is arch or stuck
problem.
5A
Subcode 2: The braking IGBT
is short circuited.
◆
Contact the agent or Inovance.
Err16
Current control
fault
Subcode 1: The excitation
current deviation is too large.
◆
Check whether the input voltage is low (often
in temporary power supply)
◆
Check whether cable connection between
the controller and the motor is secure.
◆
Check whether the RUN contactor works
properly.
5A
Subcode 2: The torque current
deviation is too large.
Subcode 3: The speed
deviation is too large.
◆
Check the circuit of the encoder.
◆
Check whether encoder pulses per revolu-
tion (PPR) is set correctly.
◆
Check whether the encoder signal is inter-
fered with.
◆
Check whether the encoder cable runs
through the duct independently, the cable
is too long, or the shield is grounded at one
end.
◆
Check whether the encoder is installed reli-
ably, the rotating shaft is connected to the
motor shaft reliably, or the encoder is stable
during normal-speed running.
◆
Check whether the motor parameters are
correct, and perform motor auto-tuning
again.
◆
Increase the torque upper limit in F2-08.
Err17

interference

auto-tuning
Subcode 1: Reserved.
◆
Reserved
5A
Subcode 2: The SIN/COS
encoder signal is abnormal.
◆
Serious interference exists in the C, D, and
Z signals of the SIN/COS encoder. Check
whether the encoder cable is laid separately
from the power cables, and whether system
grounding is reliable.
◆
Check whether the PG card is wired correct-
ly.
Subcode 3: The UVW encoder
signal is abnormal.
◆
Serious interference exists in the U, V, and W
signals of the UVW encoder. Check whether
the encoder cable is laid separately from the
power cables, and whether system ground-
ing is reliable.
◆
Check whether the PG card is wired correct-
ly.
